Nosql Essay
Now days, open source technologies are becoming famous in the global market including corporate
and government sector. A number of domains in software industry are making use of open source
products for multiple applications. NoSQL Databases, Big Data Analytics and web services are on
the top and used in diverse applications.
NoSQL Databases are being used in the social media applications and big data processing based
portals in which huge, heterogeneous and unstructured data formats are handled. NoSQL Databases
are used for faster access of records from the big dataset at back–end. The AADHAAR Card
implementation in India was done using NoSQL Databases as huge amount of information is
associated including Text Data, Images, Thumb Impressions and Iris Detection. Any classical
database system cannot handle the dataset of different types (Image, Text, Video, Audio, Video,
Thumb Impressions for Pattern Recognition, Iris Sample) simultaneously.
Currently, a number of NoSQL Databases are used for different type of portals and these are
specialized in handling heterogeneous and unstructured data.
OPEN SOURCE NOSQL DATABASES
In classical web based implementations, the RDBMS packages are deployed for the database
applications including Apache Derby, MySQL, Oracle, IBM DB2, Microsoft SQL Server, IBM
Notes, PostgreSQL, SQLite, Sybase or any other. These are known as Traditional SQL Databases
which are ACID Properties Compliant. NewSQL is the new generation database engine that

( 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

Cloud Computing Papers
Introduction Cloud Computing has been a buzz world in the past few years. The use of this
technology increased considerably when we made huge progress in this domain, reducing the cost
for everyone. Today, Cloud Computing is widely used all across the world by a lot of companies
such as Microsoft, Facebook, Amazon, etc... But what is Cloud Computing, exactly? How does it
work? How is it used? For what purpose? What can be improved in such technology? I will try to
answer these questions during this report. I will firstly define briefly the concept of Cloud
Computing with 5 simple examples of use. Then, I will talk about 2 companies (Heroku and
Microsoft) that provide cloud services and explain how they benefit to a typical company. Finally, I
will describe 2 challenges, one in research and one in commercial adaptation. Part A: Cloud
Computing Cloud computing is basically the use of large groups of resources linked together
through networking to produce a lot of performances. One of the main purpose of this technology is
the scalability that it offers. Indeed, when you need more speed or performances, the only thing to
do is to add more servers to the cloud. It has a lot of advantages, but the most valuable one for a
company is that they pay for what they use, and don't have to buy some powerful servers "just in
case" they will need more resource. This technology is a huge money–saver. There are different
services models used in cloud computing: Infrastructure as a Service

Relational Database Management System ( Rdbms )
Background
This report provides analysis and evaluation of how Relational Database Management System
(RDBMS) can be applied to improve organization and business effectiveness. The method of
analysis includes basic information of Relational Database Management System and reference of
how database management can bring positive improvement on manage small or large amount of
information in the organization. Also, include a brief information of business those are successful in
their field's thanks of the application of database system in their organizations and recommendations
to apply Relational Database Management System to the company.
Analysis
Relational Database Management System (RDBMS) is an engine/system based on the relational
model created by Edgar F. Codd in 1970. The major distinguish of this system is the ability to use
tables for data storage while maintain and enforce certain data relationship. Another aspect of this
system is that allow users to insert, update, retrieve, and delete specific content or contents storage
in the database. Also, RDBMS provides relational operator codes that enable the relationship
between two or more entities in a database (Dangerfield & Morris,1990). These system's
characteristics can be applied on business operations improving company management of small and
large amount of information from a specific department or workplace. Relational Database
Management allows monitoring all information flow from that specific department

Database Analysis : Database Management System Essay
Databases are fundamentally containers for data. When data for any organization needs to be stored,
databases can be used. For example, let's say a public library stores books, we could say that the
library is a database of books. But specifically, databases are computer structures that save,
organize, safeguard and produce and/or deliver data. A database platform is essentially a database
management system (DBMS) which is a computer software application that interacts with the user,
other applications, and with the database itself to capture and analyze data. A general–purpose
DBMS is designed in a way to allow the definition, creation, querying, update, and administration of
databases1. Before we dive deeper into databases and the types, we need to know the difference
between what a database is and what a DBMS is so we don't confuse ourselves.
Database is a collection of related data stored in several different tables, and linked with each other
using foreign keys. A DBMS is a Database Management System, is a piece of software that manages
databases and lets you create, edit and delete databases, their tables and their data. Examples of a
DBMS include, MySQL, MY SQL Server, Oracle, PostgreSQL, and SQLite.
When Organizations involved in combining various data sources may well be looking to source a
Database Management system. There are various factors to consider during the process. Some of the
factors include:

4.5 Testing phase In this module, the class label for the testing data is predicted. The n –
dimensional feature vector for the testing data is converted from query tree of testing data in the
manner similar to the data pre – processing phase. The SQLIA classifier determines the new testing
feature vector is normal or malicious, by using optimized SVM classification model. 5. Results and
discussion From Table 1 we can depict the generation time of the multi – dimensional sequences,
feature transformation and n – dimensional vector for both normal and malicious queries. We
observed that the total sequence generation time for all the normal queries is 31.111 seconds. The
total feature transformation time is 7.867 seconds. And the time taken to generate the vector is 6.932
seconds. The sequence of all malicious queries is generated in 6.096 seconds. The time taken for
feature transformation of malicious queries is 3.799 seconds. And finally, the vector generation time
of malicious queries is 2.511 seconds. Table 2 illustrates that the second, third and fourth kernel
parameter gives the highest accuracy. The performance of the classifier can be evaluated by using

The main focus of this project is reducing the feature extraction time of the system. As a conclusion,
it shows that our framework extracts the features from the parse tree very fast. This paper can be
further enhanced by using the hybrid classification algorithm to get more accuracy in classification.
In this paper, the parse tree is obtained from the PostgreSQL databases and in future, it will get from
MySQL databases. To decrease the feature extraction time, fragmented files will be processed in

Object Storage Systems Are Complex Systems
Data Indexing
Object storage systems are complex systems that require high–speed data management system to
handle the vast amount of object attributes. In CADOS, we take advantage of PostgreSQL
(Stonebraker and Rowe, 1986) database to store the object and stripe information. Namespace
technique is widely used to prevent the name conflict of objects with the same name. Each object in
CADOS is accessed via well–defined namespace paths. The object path column is represented via
ltree structure (ltree, 2015) in order to support hierarchical tree–like structure in an efficient way.
This structure allows us to use regular–expression–like patterns in accessing the object attributes.

All the communication between the master web worker and slave web workers are made in a
message–passing fashion. At (2), master web worker distributes the URL list of the data segments
across the slave web workers which are created in the loading event of the web page. onmessage is
an event handler that is called when the message is posted to the corresponding web worker. In
onmessage handler of the slave web workers, unique IDs with URLs are posted to the slave web
worker, then each slave web worker starts retrieving data segments from the cloud object storage,
again, by means of AJAX communication technique (3). As the slave web worker finishes the
retrieval of the data segment, it posts the data pointer and corresponding index to the master web
worker (4). Index of the data segment is used to locate the data segment on the main cache created
by the master web worker. Because the data is passed to the master web worker using pointers, there
is no data copy overhead. Once all the slave workers finish data retrieval operations, the master web
worker writes out the cache to the hard disk (5). The downside of this technique the total amount of
retrieved data is limited by the RAM capacity of the user, although we anticipate this feature to be
introduced in the future as a part of HTML standard with the introduction of the File API:

Open Source Software For Database Server
In this task, I will be looking at some open source software for a database server, Web server, file
server, SMTP server, and an LDAP server. I will go over a few in each category and then make my
recommendations based on the stability and security of the software as it relates to the need of the
First World Bank. First, I will be looking at some open source software for the database server. I am
going to be at the two that I consider be our organization's best options. Those two are MySQL and
PostgreSQL. MySQL is considered the most popular of all the open source database systems. It
offers a variety of database features and is considered fairly quick and pretty secure. It would be a
good choice for the company's database servers. However, unfortunately "MySQL does not [try to]
implement the full SQL standard, this tool is not completely SQL compliant. If you might need
integration with such RDBMSs, switching from MySQL will not be easy" (Tezer 2014). This makes
it not entirely ideal for current situation. When we take a look at PostgreSQL, we see that
"PostgreSQL is the advanced, open–source [object]–relational database management system which
has the main goal of being standards–compliant and extensible" (Tezer 2014). For the type of work
our company is looking to achieve, it is very important that our database system be both highly
secure and standards–compliant. The downside of PostgreSQL is it is considered slower than
MySQL and it is not as popular.

Enforcing Consistency With Explicit Blocking Locks
When using this technique, it will avoid creating an unnecessary burden for application
programmers if the application software goes through a framework which automatically retries
transactions which are rolled back with a serialization failure. It may be a good idea to set
default_transaction_isolation to serializable. It would also be wise to take some action to ensure that
no other transaction isolation level is used, either inadvertently or to subvert integrity checks,
through checks of the transaction isolation level in triggers. 13.4.2. Enforcing Consistency With
Explicit Blocking Locks When non–serializable writes are possible, to ensure the current validity of
a row and protect it against concurrent updates one must use SELECT ... Show more content on

Doing the two sums in a single repeatable read transaction will give an accurate picture of only the
effects of transactions that committed before the repeatable read transaction started – but one might
legitimately wonder whether the answer is still relevant by the time it is delivered. If the repeatable
read transaction itself applied some changes before trying to make the consistency check, the
usefulness of the check becomes even more debatable, since now it includes some but not all post–
transaction–start changes. In such cases a careful person might wish to lock all tables needed for the
check, in order to get an indisputable picture of current reality. A SHARE mode (or higher) lock
guarantees that there are no uncommitted changes in the locked table, other than those of the current
transaction. Note also that if one is relying on explicit locking to prevent concurrent changes, one
should either use Read Committed mode, or in Repeatable Read mode be careful to obtain locks
before performing queries. A lock obtained by a repeatable read transaction guarantees that no other
transactions modifying the table are still running, but if the snapshot seen by the transaction predates
obtaining the lock, it might predate some now–committed changes in the table. A repeatable read
transaction's snapshot is actually frozen at the start of its first query or data–modification command
(SELECT, INSERT, UPDATE, or DELETE), so

Relational Database Management Systems ( Rdbms )
Introduction
Nowadays, data is being generated by multiple sources around us at an alarming rate, be it sensors,
in the form of social media communications or mobile devices. It has become an important part of
an organization, Such data is called big data and the insights from big data can help examine trends,
understand customer preferences and help the organizations take better decisions which results in
better customer service and effective marketing.
Relational Database Management Systems (RDBMS) provides an efficient way for storage and
processing of data but have limitations when it comes to handling Big Data.
Apache Hadoop is an open source framework and its helps in the distributed processing of
Big Data. Hadoop works on a distributed model, has a built in fault tolerance and handles scalability
very efficiently. It is able to process data of size petabytes with help of its Map
Reduce Programming model and Hadoop distributed File System.
RDMBS even with parallelizing capabilities and sharding the databases do not scale well for large
data sets and are also not cost effective. It is challenging for RDBMS to handle the data size which
has increased to petabytes and exabytes. The content from social media, text, video, audio, etc is in
semi–structured or unstructured format which cannot be handled by RDBMS. Also, big data grows
at a very rapid rate, as an example online retailers maintain records of all the customer interactions
in the form of what

In 15 October, 2014 this attack was identified by Google security team under the vulnerability
CVE–2014–3566 in SSLv3 protocol. In this POODLE attack the bug has been found that exploited
the intercept data that is supposed to be encrypted between system and the server. According to the
researchers who found the bud, an attacker/Hacker interferes between the computer and the server
with the handshake process. This handshake process is used to verify which cryptography protocol
the server can accept using a "protocol downgrade dance". By doing this the computers are forced to
use the older SSL 3.0 protocol to protect data that is being sent. Hackers can then easily exploit the
bug by carrying out a man–in–the–middle (MITM) attack to decrypt secure HTTP cookies, which
could let them steal information or take control of the victim's online accounts. The information to
test websites weather they are affected with POODLE was given by the

Internet Servers (also commonly known as Web Servers), primarily function to deliver web pages on
request to clients. When a user types a domain name into their browser, or clicks on a link, the
request is first sent to a Domain Name Server (DNS). DNSs are servers that hold databases full of
domain names and IP addresses. When a DNS receives a request, it matches the domain name (ie,
www.CriketX.com) to the IP address of the server that holds all of the files that make up that
particular website and sends that information back to the user's browser. The browser can then send
a request for those files to the IP address of the web server (205.134.224.227 for

VB development tools as well as Access and MS SQL cannot be run on Linux servers, which is why
Windows servers are a big hit with Microsoft technology fans. When it comes to system security,
Windows web servers are more prone to attacks by hackers, but this also has more to do with
administration than with the fact that it's running Windows (webdevelopersnotes.com). Also, Linux
servers perform better under heavy traffic so, in the case of shared IP hosting where multiple sites
are running on the same IP address, Linux is the better choice over Windows. Linux also offers more
ways to connect. Windows offers FTP access and it's possible to configure telnet (if your hosting
provider allows it) but Linux offers FTP, telnet, and ssh access. Linux servers are also more likely to
offer CGI and Perl access, although some Windows servers do make it available. Both types of web
servers offer server side scripting tools. When it comes down to choosing what operating system to
use on a web server, or perhaps which hosting company to sign up with, these are all things that you
need to take into consideration. In many cases, it's best to use Linux unless you have a specific
reason not to. Many content management systems such as WordPress or Joomla use PHP and SQL
which traditionally runs faster, and more reliably, on Linux systems, but can be run on Windows
web servers as well. Of course, if your site has been built using Windows–specific languages and

Database Management System For A Company
A research database management system (RDBMS) is the most used database management system
for a company. Its roots date back to 1970, created by E.F. Codd at IBM. The database approach
involves the storage of data involving tables. Attributes of the tables involve rows, used as a record
of an entity. Columns, also attributes of the table, determine what will be recorded for that field.
Within a table one primary key will be found, this represents a unique column of the table. A table
may also have a foreign key, there can be more than one, and it identifies a primary key of another
table. Foreign keys allow for relationships between tables to be created.
The RDBMS is so widely used because of its simplicity to understand relationships between data.
The data can also be analyzed in many ways using queries, reports, etc. A database management
system covers all functions of the business and is essential for businesses to be run efficiently. Since
the introduction of this time of database management system in 1970 it has triumphed many former
types of widely used databases and fended off new types of databases to remain the most common
type. Times have changed in the information technology world since 1970 when IBM was running
the show and leading the world with improving and introducing new technology. I believe the top
five most used RDBMS used in the market today are Oracle, Microsoft SQL server, IBM DB2,
MySQL and PostgreSQL. Oracle database had its first

Abstract
This paper is based on the database systems. And will result in providing the whole new information
about that. Basically, database systems are the computer applications which interacts with the user
and help in maintaining the work by making them in synchronization and in a relative format
sometimes. Database systems are also help in keeping the records of utilities and securing them for
ages. This paper will tell you whole new achievements which can be done with the help of using the
database with its correct efficiencies.
Introduction
A database is an synchronized collection of the data. It is the collection of schemes, tables, queries,
reports, views and other objects. The data is typically organized to model aspects of reality in a way
that supports processes requiring information, such as modeling the availability of rooms in hotels in
a way that supports finding a hotel with vacancies.
A database management system (DBMS) is a computer software application that interacts with the
user, other applications, and the database itself to capture and analyze data. A general–purpose
DBMS is designed to allow the definition, creation, querying, update, and administration of
databases. Well–known DBMSs

Each of the vendors offers to provide training to our staff as part of the purchase. They also offer to
continue to train our staff as long as we have an account with them. Customer support is also a
crucial part of our decision. We need excellent customer support from the vendor. We also need
quick response to our request for customer support. Red Hat specifically states that it has 24/7
customer support. What that means is that twenty–four hours and day seven days a week, Red Hat
customer support is ready to provide their services. Ubuntu states that it offers profession support to
its customers. Novell also supports the use of Macs and their operation system (OS). Some of the
advantages of selecting each vendor's product are similar and still somewhat distinct. Red Hat in
(For sap business,) states, "that is a responsive customer support, higher performance standards,
collaborative engineering for better products, and designed–in security." Customer support is a very
important advantage. Higher performance standards are also an important advantage. Higher
performance means we will get what we paid for or more in our return. According to (Stevens,
2011) there are several pros and cons to using Red Hat. Some of the advantages are its scalability in
the processors and memory, ability for hot–swapping of processors, and an integrated KVM
virtualization with Kernel Samepage Merging and SELinux sandbox options. Some of the cons of

Using A Cloud Based System
The power of Internet grows drastically when people, data and things are interconnected through the
Internet. Internet of Things aka IoT, is a network of things or objects implanted with sensors and
other smart electronic devices which enables them to communicate with each other and other targets
in the network through exchange of data.
These sensors generate a lot of data that needs to be stored, managed and analyzed. There are
options to connect memory cards or computers to these sensors or we can integrate the sensors in to
devices with further networking capabilities. Most of the applications of IoT use a cloud–based
system to store and analyze data. The applications of IoT is so vast that we can expect these things
to generate massive amounts of data which has to be gathered, stored and processed quickly and
efficiently. The advantages of using a cloud–based system is that it is scalable and the data is easily
accessible through appropriate web applications. By the end of this project, the goal is to design and
set up a unix cloud–based server to store and visualize sensor data that was collected, through a web
interface.

About cloud computing:
Cloud computing is a term coined for a recent trend towards service oriented cluster
computing/processing based on certain SLA and other benefits. It provides simplified and automated
process for configuring, deployment, maintenance and easy process to manage the resources. The
offering of different clouds (Azure, google, AWS etc.) may differ, but what's common among them
is Virtualization and performance isolation for per user/application.
Cloud computing can broadly be classified into 3 broad categories:
Software as a service – SaaS describes a system in which high level functionality software as an on–
demand is hosted by a cloud and shared to end client using thin client application via internet. The
main feature of SaaS systems is that the API offered to the cloud client is for a complete software
service. The SaaS Cloud provider may charge end user based on number of users or number of
requests hit on hosted API. Example Sales Force.
Platform as a service – PaaS refers to the availability of scalable services through an interface from
which restricted network–accessible, applications written in high–level languages (Java,.net, python
etc.) can be created. Two examples of PaaS systems are Google App Engine (GAE) and Microsoft
Azure.

Database Management Systems ( Dbms )
Data is at the centre of most today's businesses and businesses must pay close attention to how they
access, store and use data. One of the systems at the heart of current data management is different
database management system.
But as with most technology product out there, people have a wide range of database technologies
and systems to choose from. Picking out the most convenient for your business can be difficult.
This guide will hope to explain what database management systems are and what are the benefits for
using one. We'll also explain some of the most common distinctions between these technologies and
provide you a few tips on how to select the best system for your business.
Introduction to database management systems
What are database management systems (DBMS)? First, it's good to understand the different
components of DBMS. At the core of DBMS is database, which is essentially an organised
collection of data. The data in database is modelled in reality in a manner, which helps supports
processes that seek information.
Creating a database is simple, but you also need to be able to use the database for different
functions. This is where database management systems come to the rescue.
A DBMS is a computer software application, which helps to interact with the user of the database,
different applications, as well the database itself in order to gather and analyse data. A DBMS allows
interaction with the data, whether it is to create, analyse, delete or change

There are numerous great open source software solutions for database servers, like, H2, HyperSQL,
MySQL, mysql, Oracle, and PostgreSQL, just to name a few. They all offer topnotch functionality,
performance, scalability, and security. As far as which one is the best, I recommend PostgreSQL.
PostgreSQL is an object–relational Database software solution that offers some of the most feature
rich options as compared to the bigger commercial manufacturers like Oracle, IBM, Sybase and
Informix, and the best part of it, it 's free. It 's also one of the first database software that was
released, and it has a proven track record with over 23 years of active development. It was created
back in 1989. The only other DB software that came out before it is Oracle, which was created back
in 1979. Now PostgreSQL might not be the fastest, but It more than makes up for it with its
functionality. It allows the use of two different types of interfaces, a GUI (for those who like the
point–click style) and a SQL. It works on most OSs like windows, Linux, Mac, Unix, etc. It has a
vast array of services and tools that is included to streamline the administration of the Database.

technology which is Sql Azure. In SQL Azure you have to use SQL Server authentication instead of
Integrated Security. When you work with SQL Azure you don 't need to spend any time on security
patches, disk space, moving databases between different servers to handle increased load, etc.
Real time database system: Real–time database is a database which provides the real time
information because the real–time database uses real–time processing to handle workloads whose
state is constantly changing. In real–time database system data objects stored in the database and
transactions accessing this data have to be scheduled in accordance with real–time performance
objectives.

means development of a quality data model. Database design is the process of transforming a logical
data model into an actual physical database. Database design is always connected with application

among entities.
Physical design: physical design is the last phase of database design. Physical design include tables,

short, a DBMS is a database program. Technically speaking, it is a software system that uses a
standard method of cataloging, retrieving, and running queries on data. The DBMS manages

Its distinguishing feature is that the schema, viewed as a graph in which object types are nodes and
relationship types are arcs, is not restricted to being a hierarchy or lattice. 3. Relational model The
relational model for database management is a database model based on first–order predicate logic,
first formulated and proposed in 1969 by Edgar F. Codd.[1][2] In the relational model of a database,
all data is represented in terms of tuples, grouped into relations. A database organized in terms of the
relational model is a relational database. Diagram of an example database according to the
Relational model.[3] In the relational model, related records are linked together with a "key". The
purpose of the relational model is to provide a declarative method for specifying data and queries:
users directly state what information the database contains and what information they want from it,
and let the database management system software take care of describing data structures for storing
the data and retrieval procedures for answering queries. Most relational databases use the SQL data
definition and query language; these systems implement what can be regarded as an engineering
approximation to the relational model. A table in an SQL database schema corresponds to a
predicate variable; the contents of a table to a relation; key constraints, other constraints, and SQL
queries correspond to predicates. However, SQL databases, including DB2,

Comments on performance As the hardware basis for such capabilities, an interactive graphics
computer station––SaberStation for short––equips the application programmer with more than
enough processing power for the job. Based on a National Semiconductor 32–bit chip set and
running at 10 MHz under the BSD Unix operating system, the unit puts the performance of a VAX–
like minicomputer on an engineer's desk. Its architecture, which employs a floating–point
coprocessor and ultrafast, 32–bit–wide DMA channels, executes 1.2 million instructions a second.
Comments on programmability Programs in this system can often, even typically, be written in a
single line of code. Inexperienced users can be taught to write simple programs in a matter of
minutes. Beginners often produce simple programs without effort within their first day using it.
The elements of the Unix environment have been called software tools. A software tool is very much
like a component, but a bit different. Throughout this piece, we'll refer to components as "tools," but
remember that you can almost always substitute "component" for "tool." In Unix, the standard shell
utilities are all tools. So is the shell. A tool takes a standard data format –– lines of textual input ––
and produces output in the same format. No special code is needed to handle data types; everyone
agrees on a simple format and does a small amount of translation.
