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

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. Adatabase 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

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

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.

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. Here are just
some examples; Full ACID (Atomicity, Consistency, Isolation, & Durability) compliancy, commercial & noncommercial support, triggers support, user

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. Adatabase 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:

DATABASE AND DATABASE MANAGEMENT SYSTEM
Database From Wikipedia, the free encyclopedia A database is an organized collection of data. The data are typically organized to model relevant
aspects of reality in a way that supports processes requiring this information. For example, modeling the availability of rooms in hotels in a way that
supports finding a hotel with vacancies. DBMS stands for "Database Management System." In 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 incoming
data, organizes it, and provides ways for the data to be modified or extracted by users or other programs. Database management systems (DBMSs) are

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 performanceAs 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 programmabilityPrograms 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.

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

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

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

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

( 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

The driving log was broken up into 11 tables. The database is in the third normal form or Boyce Codd Normal Form (BCNF) (Pratt & Adamski, 2005,
p. 153). This level of normalization ensures no repeating groups, no key column is dependent on only a portion of the primary key, and the only
determinants that are contained are candidate keys. The company has four locations in the United States and services 925 drivers. Normalization to the
third normal form is sufficient due to the relatively small database, the number of daily updates and the nature of the information. The database is

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.

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

Heartbleed is a name that security researchers have given to a serious bug found in a very common piece of software used by many websites. The
software name was OpenSSL which is used to encrypt the information that we send to and from websites. Heartbleed vulnerability in OpenSSL
allowed attackers to get sensitive data i.e. user's authentication credentials (login name, password) and secret keys through incorrect memory
handling in TLS (Transport layer security) heartbeat extension. ORIGIN OF HEARTBLEED The name heartbleed is derived from Heartbeat
extension. Heartbeat extension is an extension for TLS and Datagram TLS. This standard was proposed on February 2012 by RFC 6520. Heartbeat
provides a way to test and keep alive a secure communication link which is already created. Robin Segglemann implemented the Heartbeat extension
for OPenSSL and was introduced in December, 2011. But opensSSL was not able to find the bug and flooded the flawed code into... Show more content
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

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

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

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

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
