A Research Study On Relational Database Technology

A Research Study On Relational Database Technology
Abstract. In this report I will introduce the Memcached technology and provide more details about
it. In addition, I will explain how it works and how it differs than relational database technology.
Furthermore, I will use the finding of the paper "Performance Evaluation of a Clustered
Memcached" to present how Memcached can improve the performance of the web applications. The
paper that I did study is about a simulation project of using three different architectures of
Memcached. The simulation results will monitor the CPU and RAM usability of all the nodes in
these three architectures. I will explain the results and will discuss the findings of their results.
The relational database technology dominated the web applications for more than 30 years. This
technology is able to handle limited load to the database. However, the internet technologies and the
advents of the smart phones make the web applications to be accessible by many users and from any
location that is covered by the internet connectivity. In addition, currently, the web data in the
internet is dominated by the social networking and social media applications which include:
Facebook, Twitter, YouTube, Instagram and others. This kind of web applications will likely be
prone to the high load of the database layer. As a result, it was not possible for the relational
database technology to handle the database load for such applications. Even scaling out the
application servers will not solve the database load

Database Protection System For The Security Of The...
Abstract:
In the last 5 years the usage of internet has increased vastly. Internet attacks has been increasing. As
attacks are increasing there is no security for the network related data bases. We need urgently a
database protection system against the attacks in order keep the data securely.
This paper reviews about the SQL attacks, database protection system which is used between the
database and web application. There are different protective measures for the different users to
provide effective security of the database.
Introduction:
Since the rapid increase of use of Internet, computer network technology has rapid growth. Now a
day's internet is used in almost every fields like governments, business and health care and schools
etc. made the rapid development of the computer network technology.
Networks play key role in these computer era. It brings convenience, along with it also brings the
malicious attackers. Network attackers are targeting the network database, to get the secured data.
The most common attack are SQL attacks. SQL statements are the tools of SQL attacks.
SQL Attacks:
The Principles of SQL attacks:
The most common attacks on the web are SQL attacks. SQL means Structured Query Language.
SQL is used by the relational databases to perform the database operations. Generally web servers
use databases to store the information. Every site on the web mostly uses the databases. SQL is also

Analysis on Key–Value Stores
Introduction
We have come into the era of Big Data. As (Atikoglu, Xu, Frachtenberg, Jiang, & Paleczny, 2012)
stated, the need for efficiently storing large–scale data in scale–out companies at lower cost is
dramatically increasing. Therefore Key–Value Store has occurred in popularity. (Fitzpatrick, 2004)
has clarified that KV stores plays an essential role in lots of huge websites such as Facebook,
Twitter, GitHub and Amazon. This paper reviewed 6 popular key–value stores and distinguished
primary features, performance and availability of each. The six systems are Hyperdex, Dynamo,
SILT, Project–Voldemort used by LinkedIn, Berkeley DB and LevelDB used by Google.
A key–value store database has a set of keys and values, and each value is associated with a key.
The implementation of key–value store database is actually a distributed hash table (Stonebraker,
04/2010). Key–Value Stores(KV), which are normally known as a model of NoSQL databases, are
widely deployed for data operation and management in purpose of enhancing Internet services due
to better scalability, higher efficiency and more availability than existing relational databases
systems (Wang, et al., 2014). Because KV stores sacrifice relation model in exchange for fast
writing, and they are often featured with simple methods like "put()","delete()" and "get()".
LevelDB
LevelDB is a very lightweight, simple key–value store with limited operational abilities. LevelDB
will store data in

It was definitely one of the more rewarding experiences to see my work go to use. It was also a huge
help with my own personal understanding of database modeling and database structures. I feel that
through this knowledge, I could definitely have a higher comfort level in a role that relied on a good
amount of database knowledge. Another one of the tasks that I got to take on had to deal with our
lease agreements. At Duquesne Light, we use various cell tower sites to attach our own equipment
that picks up readings from meters, and then bounces those readings back to a data center. In order
to attach our equipment, we pay leases to various companies that own the spaces that we use. The
majority of our leases are paid on a yearly basis, but some of them are paid on a monthly basis. Up
until now, we had only had our files semi–decently organized files put away into the filing cabinets
and scattered throughout a network drive with very little organization. Because of this lack of
organization, we were paying many of our lease agreements past their due dates and forcing us to
incur late fees on top of our payments. I took on the task of organizing these files and setting up a
payment schedule inside of our company SharePoint, which was being far underused. I had to go
through and check the payment dates and find out when they were supposed to be paid, organize
them in an offline backup, and take them online to SharePoint. By doing this, we have been able to

The Importance Of In Health Service Organizations
The Importance of Dashboards in Health Service Organizations Introduction The core of any
successful health service organization's mission is to improve the quality of patient care and
satisfaction all the while maximizing profitability. Health service's executives are responsible for
initiating fiscal strategies, planning for favorable outcomes, and executing their vision and
measuring operational key performance indicators (KPI's). KPI's indicate how well their
organization is achieving value through financial and clinical metrics that help drive vision and
mission. To do this well, health service leadership require a 360–degree perspective of their
organization's business performance to view and quickly understand where their organization
compares universally. The Business Intelligence dashboard is a streamlined, easily accessible, and a
more accurate and significant reporting process. It presents the ability to gauge performances,
understand the impact of perpetually changing conditions; it assists in making quick and well–
informed decisions for performance scenario planning, as well as what–if–analysis, at all various
levels of comprehensive and real–time information. In short, the dashboards provide a succinct and
yet visually appealing snapshot of an organization's performance, as a result, leadership create
accountability and are better able to focus on more value added activities for proactive guidance for
employees to work consistently together as a whole.

Database
It is the collection of schemas, tables, queries, reports, views, and other objects. The data are
typically organized to model aspects of reality in a way that supports processes requiring
information, such as modelling the availability of rooms in hotels in a way that supports finding a
hotel with vacancies. It is a structured set of data held in a computer, especially one that is
accessible in various ways.
A database is a collection of information that is organized so that it can easily be accessed, managed,
and updated. In one view, databases can be classified according to types of content: bibliographic,
full–text, numeric, and images. In computing, databases are sometimes classified according to their
organizational approach. The most prevalent approach is the relational database, a tabular database
in which data is defined so that it can be reorganized and accessed in a number of different ways. A
distributed database is one that can be dispersed or replicated among different points in a network.
An object–oriented programming database is one that is congruent with the data defined in object
classes and subclasses.
Computer databases typically contain aggregations of data records or files, such as sales
transactions, product catalogues and inventories, and customer profiles. Typically, a database
manager provides users the capabilities of controlling read/write access, specifying report
generation, and analysing usage. Databases and

1.1 SAP HANA Database Engine Architecture
SAP HANA is an in–memory technology platform that is deployable as an appliance or in the cloud.
Its core is the SAP HANA database, which is built for high performance applications. It makes full
use of the main memory and processing power provided by modern hardware. As relevant data is
kept in main memory, read operations can run in main memory. SAP HANA is also designed to
make full use of multi–core CPUs by parallelization of execution. Research ... Show more content

Application–specific services provided by the XS server are either created declaratively or by
writing server side application code. The XS server also hosts several system services, for example
for data replication, and for analytical queries and search queries over HTTP. Several web–based
tools included with SAP HANA are also running on XS, for example for development, system
administration, and life cycle management.
The name server owns the information about the topology of a SAP HANA system. In a distributed
system, the name server knows where the components are running and which data is located on
which server.
The SAP HANA studio is both development environment and administration tool. Administrators
can use the SAP HANA studio for example to start and stop servers, to monitor the system, to
configure system settings and to manage users and authorizations. As shown in figure 4, the SAP
HANA connects to the SAP HANA servers via SQL. Developers can use the SAP HANA studio to
create content such as data models, modeled views or procedures. These development artifacts are
stored in the SAP HANA repository. The SAP HANA studio is based on the Eclipse platform.
In addition to SAP HANA studio, there are also web–based tools for administration and
development. The server side parts of these tools are system applications that run in the XS server.
Web–based development tools can be used to perform most development tasks in a browser. Web–

Application development and use has been changing for several years. The growth of software–as–

unable to meet. Relying on vulnerability scanners that used public databases of vulnerabilities can
have disastrous consequences, but it was often necessary to do so. However, scanners cannot defend
against a vulnerability that they cannot identify – and therein lies the problem.
The problem becomes especially acute for cloud–based applications. Vulnerabilities in shrink–

Either the engineers are inherently better at developing cloud–based software that is remarkably free
of vulnerabilities – or the vulnerabilities are not included in public databases of vulnerabilities. The
latter choice is the more logical conclusion.
Whether apps are developed by an ISV or by a third–party provider, the chances are excellent that
the apps will contain third–party libraries, recycled code snippets and/or open–source code or
libraries. Often, all of these elements exist within the API used to develop the application. Building
on what already exists can make application development faster and more economical, but it also
carries the risk of an unknown vulnerability being repeatedly incorporated into numerous – and
frequently diverse – applications. Although these vulnerabilities may be new, it is also possible that
they have gone undetected for months or even years. However, since the SaaS vendor's
infrastructure is in AWS and the application is deployed on AWS, neither the network nor the
application is available for the rest of the world to scan.
Clearly, the way that SaaS vendors approach security is due for a change. Every application is
different, and relying on public databases to identify vulnerabilities in SaaS applications is asking
for trouble. Although the practice of identifying vulnerabilities existing within

RDBMS stores the data in the form of tables and can be retrieved from the tables with the help of
SQL Language. SQL was invented only after the invention of RDBMS. SQL – Sequential Query
Language. Most common RDBMS's are My SQL, DB2, Oracle, and Microsoft SQL. The reason for
using RDBMS rather than a DBMS is that DBMS stores data in the form of Files whereas RDBMS
stores data in the form of Tables containing rows and columns and there exists a primary key
relationship such that the data stored in multiple tables can be retrieved using SQL. As RDBMS is a
relational database model, the data is stored in the tables in the form of relations. RDBMS supports
Distributed database and is designed to handle large amounts of data.
Database research and associated standardization activities have successfully guided the
development of database technology over the last four decades and SQL relational databases remain
the dominant database technology today. This effort to innovate relational databases to address the

Database Modeling, System Design, And Improve Performance
MODELING
As databases and technology have evolved, Elmasri and Navathe point out that increasingly
complex data structures for modeling to meet the needs of the more advanced and larger databases
that were also beginning to include newer data types (2016). As stated before, with more complex
databases, there are more vulnerabilities in security that need to be planned for and mitigated
wherever possible. A DBMS is responsible for designing the methods in which data recovery and
security is handled, while tools are used within database modeling that facilitate modeling, system
design, and improve performance (Elmasri & Navathe, 2016). When applying these tools to
database creation, security should always be considered in each step of modeling and creating the
database. The DBMS provides a security and authorization subsystem to the DBA so that they can
use it to create accounts and specify account restrictions (Elmasri & Navathe, 2016).
AGGREGATION AND INFERENCE
Aggregation occurs when a user combines individual pieces of data that they have access to in order
to infer more of the bigger picture which they do not have access to, which can happen when a user
only has access to some records but draws enough information from the ones they do have access to
in order to figure out information that has been deemed off limits to them (Harris, 2002). This is, of
course, a potential security risk which should be corrected. On the other hand, knowledge

A Cloud Provider
ABSTRACT
Setting basic information in the hands of a cloud supplier ought to accompany the assurance of
security and accessibility for information very still, in movement, and being used. A few choices
exist for capacity administrations, while information secrecy answers for the database as an
administration standard are still youthful. We propose a novel construction modeling that
coordinates cloud database administrations with information secrecy and the likelihood of executing
simultaneous operations on scrambled information. This is th first arrangement supporting
geologically disseminated customers to join straightforwardly to a scrambled cloud database, and to
execute simultaneous and autonomous operations including those adjusting the database structure.
The proposed building design has the further favorable position of wiping out middle of the road
intermediaries that cutoff the versatility, accessibility, and adaptability properties that are inborn in
cloud–based arrangements. The viability of the proposed construction modeling is assessed through
hypothetical examinations and broad test results in view of a model usage subject to the TPC–C
standard benchmark for diverse quantities of customers and system latencies.

Creating A Distributed Operating Systems That Support...
Abstract IT industry being one of the major development areas, many people choose their career in
it. To support all range of industries i.e., from small scale to large scale, cloud computing emerged
which reduces the efforts both physically and with regard to capital investment. Depending on the
length of work that one would like to choose with, cloud computing offers four types of delivery
models namely, "public cloud", "private cloud", "community cloud" and "hybrid cloud". User is also
free to choose the amount of control one would like to have on their data that is stored in the cloud.
The cloud providers offer three types of services which give users different types of permissions.
More permissions the user hold, the more control and privacy obtained on the data. The data being
shared among the open space is less secured. Cloud computing involving different technologies like
networks, databases, operating systems and many other, has enormous security issues. In
perspective to the designing of a distributed operating systems that support cloud computing,
resource scheduling, transaction management, load balancing, concurrency control, memory
management are some of the major issues that are to be considered. Scalability, loss of data,
performance also stand as the other major concerns due to the heavy growth of organizations which
are using the cloud. This paper discusses about the several mechanisms that are to be undertaken to
improve the functionality of the operating

Is Harrah 's Entertainment, Inc. Essay
The company that I will be discussing about is Harrah's Entertainment, Inc. This company was
founded by Bill Harrah on October 29, 1937 and has its headquarters in Nevada, USA. They own
more than 50 casinos and hotels and have approximately 33,000 employees presently working. The
company has an annual revenue of $8.6 billion and is currently one of the top casino gaming
companies of the world. The reason for their success is good customer service and efficient usage of
software development. Customer service is given a top priority and many incentives are provided to
them. This makes the customers feel really happy about the services and facilities provided to them.
So the possibility of the customers returning back is very high. This is a major reason for the
success of the company.
Summary
Harrah's had initially used enterprise data warehouse from Teradata. They have now expanded their
database system since their customer base has increased. They make use of Teradata Priority
Scheduler and Teradata Dynamic Query Manager. In order to protect their system from external
attackers and to ensure total safety, Harrah's makes use of Teradata Dual Active Solutions. This
system is useful to identify customers that come for the first time and it provides services and offers
tailor made for them. The system can also alert the staff of a customer who has returned after a very
long time and make a customized greeting for such return customers. This will make the customers

Security threats
The top 3 security risks as of 2015 were as follows: –
Excessive and unused privileges
When an employee is granted database privileges that surpass the requirements of their position,
these excessive privileges could be abused. In example, a bank employee whose job requires the
ability to change only basic account holder contact info could take advantage of excessive database
privileges and add funds to their account balances or of a colleague's savings account. Further, when
someone changes position within a business or leaves it, usually his or her access rights to sensitive
data do not change. In the latter case, if these employees depart on bad terms, they can use their old

access privileges to commandeer high value data or inflict damage in a revenge attack. This tends to
happen because privilege control mechanisms for job roles were not well defined or maintained.
Therefore, employees may be granted generic or default access privileges that surpass their actual
job requirements, or even when they just accumulate such privileges over time changing positions
within the business.

Abstract:
Security of database systems has become very important Now–a–days. As many of the operations
now–a–days depend on the database systems, security became a problem because of increase in the
number of web applications. If the data is affected in an application, it not only affects that single
application but it affects the entire applications present in that system. Data may be damaged not
only from the outside damages but may be also from inside damages. Hence, we are using some of
the data security techniques like encryption of the data and decryption of the data for keeping the
data safe.

So, information control is required for the correct flow of data. For the encryption of the data, we
use the cryptographic control.
There are different types of components which provide the data protection in the DBMS. Some such
components are access control and semantic correctness. Secrecy of data is maintained by the access
control. If a person wants to make changes to the data, then it checks for whether the person trying
to change the data is the appropriate user or not by using some of the security points. By these
security points we can say that whether the person can use the data or not.
Secrecy of data can also be maintained by the use of some techniques like encryption which is
applied to the data when transmitted or when stored. Now the problem is how to change or access
the encrypted data. There is a technique called semantic correctness which verifies the semantics of
data. If the semantics are correct data can be accessed. The data is stored in the form of symbols. At
the end we can recover the data and can make sure whether the data is correct and it is available by
using of the recovery system and concurrency control.
Now the research areas are also included in the database security. There are some special techniques
involved in the research part which are order preserving and privacy preserving. The applications
mainly based on the privacy and the correctness of order.

( Query Optimization in Database Systems) To sum it up query optimization is important so that
these costs can be reduced as much as possible even as the amount of data increases. Using the
schema: users id integer, name text, rep, integer, about text) posts( id integer, title text, owner_id
text, post_id, created text) com(comment_id integer, post_id integer, comment_text text, user_id
integer), I ran a query "SELECT COUNT(post_id), created FROM posts GROUP BY created" to
get a count of how many posts were made and on what days. This took anywhere from five to ten
seconds to run which is a pretty good amount of time. The problem with the query is that it is too
simple. Every time it is run it is searching the entire database and printing everything out. For one
thing this is not ideal since it is not very readable and the information is not very specific. To make
this query better I added on "WHERE" clauses to give it a specific target. If looking for a how many
posts where created on '2010–03–27 14:53:20.727' then run query "SELECT count(post_id) FROM
posts WHERE created = '2010–03–27 14:53:20.727'. While that seems simplistic for the topic, it is
worth noting since a big part of optimizing queries is knowing what you want and specifically

processing power required to run the applica–tions is supplied by the cloud provider. No initial setup
costs: applications are ready to use once the user subscribes. Pay for what you use: if a piece of
software is only needed for a limited period then it is only paid for over that period and
subscriptions can usually be halted at any time. Usage is scalable: if a user decides they need more
storage or additional services, for example, then they can access these on demand without needing
to install new software or hardware. Updates are automated: whenever there is an update it is
available online to ex–isting customers, often free of charge. No new software will be required as it
often is with other types of applications and the updates will usually be deployed automatically by
the cloud provider. Cross device compatibility: SaaS applications can be accessed via any internet
enabled device, which makes it ideal for those who use a number of different devices, such as
internet enabled phones and tablets, and those who don't always use the same computer. Accessible
from any location: rather than being restricted to installations on indi–vidual computers, an
application can be accessed from anywhere with an internet enabled device [15]. To get the
maximum out of SaaS, another emerging characteristic called multi–tenancy is needed to be

Detecting And Protecting Against Inside Threats
Felipe Affonso Kaustubh M. Phaltankar April 18, 2016 Detecting and protecting against inside
threats Introduction Each day our world and our lives depend more on information systems, systems
that can guarantee that our informations are secure and available just for our own purpose. Lots of
companies work just if critical information which is stored on their databases. It is the responsibility
of these companies to guarantee with their costumers that this data is secure. Lots of those
companies are concerned about their databases and try to improve their security however. According
to last year 's Internet Security Report from Symantec, almost no company, whether large or small,
is immune to cyber attacks. Five of every six large companies (2500+ employees) were targeted
with spear–phishing attacks in 2014, a 40 percent increase over the previous year[1]. Normally,
companies are aware of theses attacks and are trying to invest more and more in security. It's
important to point out that attacks are not just from the outside; breaches and even data leakage can
be accomplished by inside employees. So, it's really important to protect against inside and outside
attacks. High–tech businesses rely primarily on two opposing information values: the dissemination
of information for innovation success and the protection of information to retain competitive
advantage[2]. These companies know that just physical security isn't enough anymore, it's necessary
to implement different

Improving the Records Management
Improving the Records Management
Implementation of Electronic Records Management Records management can be improved in many
ways. In my opinion, one of the ways is to implement the electronic records management. The
government should consider formulating policies, standards and practices, technical specifications
and training plans to enable its agencies including Mahkamah Negeri Sembilan to manage records
in electronic form. According to Arkib Negara Malaysia, The management of electronic records is
not a problem that needs to be solved. Its effective implementation in support of program/ service
delivery, decision–making, etc., should be viewed from the perspective of the extent to which it can
lead to cost savings, cost avoidance, risk reduction and opportunity gain. This means that electronic
records could give a lot of benefits to the government agencies. As stated by Arkib Negara
Malaysia, electronic records management could help the government agencies to reduce its costs.
The traditional records management practiced by Mahkamah Negeri Sembilan for example requires
the government to actually spend more money. This is because, if we're looking this issue from a
strategic view then it is undeniable that the implementation of electronic records management could
save costs. The existing system practiced by the government requires them to maintain all the
equipments and also hire personnel to supervise the files room. Furthermore, it contributes to the
increased usage

Introduction: Lotus note has been one of the first complete Groupware products to hit the market
way back in 1989, and ever since it has continued to dominate groupware market. Developers of
Notes realized the importance of Security quite early, and therefore we see many industry Standard
Security Features built in Notes over and above Security Features unique to the Notes. Together,
they effectively cover many aspects of Security that are of significant importance today. Notes has
layered Security model that provides Security features at two broad levels: Application Level –
Features available to Notes Application Developers. Administration Level – Features available to
Notes System Administrators. This paper aims to discuss the importance of Administration level
security features of Notes with a focus on explaining the security they provide, their usage and their
Limitations/vulnerabilities. Application level security features are not discussed here because it

In the end the performance of software Defined Optical Networks is evaluated.
Keywords– Software Defined Networks, Optical Networks.
1. Introduction
The major goal of Software Defined networks is separate the control plane and the data plane and
passing the control to a SDN controller for the programmability of the network resources. The SDN

architecture consist of basically 3 layers– (i) the infrastructure layer (ii) the control layer and (iii) the
application layer (from top to bottom). The connecting interface between the control and application
layer is termed as the NorthBound Interface while between the control layer and the infrastructure
layer is termed as SouthBound Interface. The SouthBound Interface uses the Open Flow Protocol to
communicate with the lower level switches. The Controller is the main intelligent device present in
the architecture that offers a centralized view of the whole network [1].

Optical Networks provide a way of transmitting the user signal in an optical medium by converting
them into light signals. Recent advances in the optical networking technologies enables the transport
networks to be more intelligent and allows more flexibility in multiplexing and switching functions

1 Executive Summary
Lately with the development of distributed computing, issues services that utilizes web and require
enormous amount of data come to forefront. For Organizations like Facebook and Google the web
has developed has a vast, distributed data repository for which handling by conventional DBMS is
not sufficient. Rather than extending on the hardware capabilities, a more realistic approach has
been accepted. Technically, it is an instance of scaling through dynamic adding servers from the
reasons increasing either information volume in the repository or the number of users of this
repository. In this scenario, the big data problem is frequently examined and in addition explained
on a technological level of web databases.
Dealing with this issue was more and more difficult using relational database technology.
Pioneering work from large companies generated tremendous interest and open source NoSQL
database projects formed to leverage the work of the pioneers. Today, the use of Key/Value database
based on NoSQL technology is increasingly viewed as a practical alternative to relational databases,
particularly as more organizations recognize that working at scale is all the more effectively
accomplished running on clusters of standard and a schema less data model

Social Media And Its Effects On Society
Algorithm has become a term that is constantly intertwined with social media. Online platforms
have become a place where archives and algorithms are used to provide us with content as well as a
platform for users to participate and share information (Louw & Carah, 2015). Algorithms are used
to connect people to the content that interest them without the need to search for it on their own
(Hallinan & Striphas, 2014). Charlie Brook's Black Mirror episode, Be Right Back (2013), has
triggered us to think about how the information that we share on social media is archived and used
to create customised forms of content and continuously engage us on media platforms. In this essay
I will be discussing key ideas drawn from the episode. Firstly, databases are created from archives
which grow as participation of users increase over time. Secondly, the information is made useful by
sorting and analysing them with algorithms to create customised content for users. Thirdly,
personalisation of content has benefits, however, it raises some consequences on the society. I will
further illustrate the ideas from real world examples such as Netflix and Facebook. Databases are
created from accumulation of archives as users participate. Data is any type of content that is
collected from activities that happens on the platform converted to a digital form (Carah, 2016).
Platforms watch and learn user's actions to predict future behaviours (Louw & Carah, 2015). In the
film, the media platform was

Mongodb : The Most Prominent Nosql Database Framework
INTRODUCTION
MongoDB is one of numerous cross–stage archive situated databases. Named a NoSQL database,
MongoDB shuns the customary table–based social database structure for JSON–like archives with
element constructions (MongoDB calls the organization BSON), making the combination of
information in specific sorts of utilizations less demanding and quicker. Discharged under a mix of
the GNU Affero General Public License and the Apache License, MongoDB is free and open–
source programming.
Initially grew by the product organization 10gen in October 2007 as a part of an arranged stage as
an administration item, the organization moved to an open source improvement show in 2009, with
10gen offering business backing and different administrations. From that point forward, MongoDB
has been received as backend programming by various real sites and administrations, including
Craigslist, eBay, Foursquare, Source Forge, Viacom, and the New York Times among others.
MongoDB is the most prominent NoSQL database framework.
DESCRIPTION:
MongoDB was first developed by the software company 10gen now called as MongoDB Inc. in
October 2007 as a component of a planned platform as a service product, the company shifted to an
open source development model in 2009, with 10gen offering commercial support and other
services. Since then, MongoDB has been adopted as backend software by a number of major
websites and services, including Craigslist, eBay, Foursquare, Source Forge, and The New York

Web Analytics Essay
Before understanding what is web analytics we should understand what is analysis?
Analysis is the process in which we perform detailed examination of anything such as data, any
element or any structure and we used certain techniques to perform this analysis.
Now, what is web analytics? Web Analytics is the process which is used to analyze any website's
large data with the aim of understanding and optimizing web usage.
Web Analytics involve several steps to perform: –
1. Firstly, we need a data to analyze and every website contain some log files which contain
website's raw data which we need to analyze.
2. Secondly, we analyze that raw data with the help of web analytics software (such as tableau) and

This will save the time for page load. Page load time has a significant impact on any user experience
it might convert a visitor into a buyer. Thus, Page caching is also one of the important factor to
determine any website's ranking.
Challenges of Page Caching: –
1. It requires frequent updating of website content.
2. Storage is also quite limited for caching. Therefore, there is always a limit to how much data
should be stored in caching tools
Search Robots
Search Robots are the tools which are used by many web search engines such as Google, Yahoo, to
build their databases. Search Robots can also be termed as bots, crawlers and spiders.
How Search Robots work?
Search Robots stores list of URL's that it can index and then it downloads the respective documents
regularly and while doing this process if search robot finds new link then it also adds that link to the

list. Whenever Search Engine Robots arrives at a website it starts looking for a robots.txt file. The
robots.txt file is used to block some areas of the site from search engine robots. After retrieving all
the data and building the search engine index, the search engine engineers build some rules and
algorithm which are used to evaluate the information which the search engine robots retrieved. And
when the user enters a query into the search engine, the search engine performs some tasks and

Essay about Getting to know a few Differential Private...
1.2. Differential Privacy to the rescue.
Privacy is a major problem these days. Cheaper memory has led to immense amount of data
continuously being accumulated in various databases across the world, from universities, companies
to patient records, content and link graphs of social net–works, mobility traces in cellular networks,
book and movie ratings, etc.–and there are many socially valuable uses to which it can potentially
be put. But, as Netflix and others have discovered, even when data collectors try to protect the
privacy of their customers by releasing anonymized or aggregated data, this data often reveals much
more than intended, especially when it is combined with other data sources. This calls for the need
to immediately ... Show more content on Helpwriting.net ...
Such a method is highly applicative for a wide variety of applications, be it Netflix or Twitter data to
be analyzed by a Data Scientist. An adversarial querier could not, for instance, obtain an accurate
answer to the query "Has John followed Mark?" because the cost of such a query would exceed any
reasonable privacy budget.
Even though everything seems fine till now, the adversary can still attack the user's data. This is
because we have assumed that all that the adversary can notice is the output of the query. However,
the adversary can also notice the time taken for the system to reply to the query. Such observations
can be exploited to mount a covert–channel attack. To continue with our earlier example, the
adversary might run a query that always re–turns zero as its result but that takes one hour to
complete if John Doe follows Mark and less than a second otherwise. Both Airavat and PINQ would
consider such a system to be secure since the output is differentially private. However, the adversary
can still learn with perfect certainty whether John follows Mark–a blatant violation of differential
privacy.
Fortunately, the user's access to the database only via queries leads to channels like power
consumption [9] and electromagnetic radiation [5, 8] being ruled out, henceforth, leaving the
adversary with just two channels: the privacy budget and the query completion time. These

Software restriction policies are designed to identify software and control its execution. In addition,
administrators can control who will be affected by the policies. 5. What about Configuring Software
Restriction Rules? The functionality of software restriction policies depends on the rules that
identify software, followed by the rules that govern its usage. When a new software restriction
policy is created, the Additional Rules subfolder is displayed. This folder allows you to create rules
that specify the conditions under which programs can be executed or denied. The rules that are
applied can override the Default Security Level setting when necessary. 6. What does Network zone
rules do? It can control from a specified zone, such as a local computer, a local intranet, trusted
sites, restricted sites, or the Internet. This type of rule can be applied to allow only Windows
Installer packages to be installed if they come from a trusted area of the network. For example, an
Internet zone rule could restrict Windows Installer packages from being downloaded and installed
from the Internet or other network locations. 7. What about application install, how to set this? The
package is set to Assigned, the Install This Application At Logon option is available. This option
allows the application to be installed immediately, rather than advertised on the Start menu. If users

met. Bumbles are noted down and corrected in a split second. Unit testing is the vital and critical
part of the wander, so errors are changed successfully particularly module and program clarity is

Tablet Server At Any Point Of Time
Tablet Assignment A tablet is assigned to one tablet server at any point of time. The master is
responsible to keep track of the set of live tablet servers, and the current assignment of tablets to
tablet servers, including which tablets are unassigned. If a tablet is unassigned, and place is
available in a tablet server; the master assigns the tablet by sending a tablet load request to the tablet
server. Chubby keep track of tablet servers. When a tablet server starts, it creates, and acquires an
exclusive lock on, a uniquely named file in a specific Chubby directory. The master monitors this
directory (the server's directory) to discover tablet servers. Whenever a master is started by the
Bigtable cluster management system, it executes the following steps to discover the current tablet
assignments (1) The master grabs a unique master lock in Chubby, which prevents con–current
master instantiations. (2) The master scans the server's directory in Chubby to find the live servers.
(3) The master communicates with every live tablet server to discover what tablets are already
assigned to each server. (4) The master scans the METADATA table to learn the set of tablets. (5)
Builds a set of unassigned tablet, which are become eligible for assignment. Tablet splits are treated
specially since a tablet server initiates them. The tablet server commits the split by recording
information for the new tablet in the METADATA table. When the split has committed, it notifies
the master.

Nice Pak Pdi Is A Family Owned Business
Nice–Pak PDI is a family owned business which is one of the largest wet wipes producer in North
America. They are doing manufacturing for contract, private label and branded products. To
determine their strongest and weakest territories, products and customers they are gathering sales
tracings data from their distributors. At current, sales team collecting their own tracings data and
analysis them to see who is their best and worst customers, products and territories. It is really
difficult for the sales team to do this analysis as they are doing manually. They spend almost 15%–
20% of their time to create their reports and submit to their superior. Here is the main difficulties
which sales team are facing currently.
 There is no reporting modal for sales team. They create their own reports and submit.
 They are not be able to analyze their territory unless they download these data and generate the
report for that customer or product or territory.
 Some time they missed the opportunities for the new sales as data is not rapidly available.
 It is hard for the regional directors to submit their report to the management as they have to rely
on their territory sales manager to create and submit their reports.
 Sales team has to wait almost 40 to 50 days to get their tracings data as there is no direct feed to

Application Of Management Information Systems
Management Information Systems
Businesses have used computers since the 1950s to assist in the operation of daily activities.
Accounting tasks were the first to be solved with computers, which started the process of
developing information systems. The early computers were large and bulky and took up the space of
an entire room. Typically these computers can only handle one task at a time and were only allowed
to be used by one user at a time. Today technology is all around us and used on a day–to–day basis.
This information is so vast that it requires a management process to keep it organized and in order.
With the implementation of a personal computer, also known as a PC, along with networking,
multi–user systems and applications, allows users to enter their own data, and has relieved most of
the original computer problems of data input and processing. According to Wikipedia management
information systems, also abbreviated as MIS, is the study of people, technology, organizations and
the relationships among them. Our book elaborates stating that management information systems is
a specific form of information technology that managers utilize to generate the specific, detailed
information they need to perform their roles effectively. Since the subject is so broad with this paper
we are going to take a look at what materials are covered within Management Information Systems
and why these are important. The materials discussed with be managing data resources, business
