What is MS SQL?

It is a relational web hosting database that is used to store web site information likeblog posts or user information. MS SQL is the most popular type of database on

Windows servers. It is not free but it has many advanced features that make it

suitable for businesses.

What is MS SQL capable of?

In basic terms, an MS SQL database is capable of storing any type of that youwant. It will let you quickly store and retrieve information and multiple web sitevisitors can use it at one time. You will use SQL statements to accomplish all of

this. In more technical terms, most versions of MS SQL have the followingfeatures:

Buffer management

Logging and Transaction

Concurrency and locking

Replication services

Analysis services

Notification services

Integration services

Full text search service

Stored procedures

Triggers

Views

Sub-SELECTs (i.e. nested SELECTs)

What is MS SQL used for?

MS SQL is the database of choice for web applications on a Windows platform

(using .NET or ASP). These languages make is extremely easy to connect to a MS

SQL database. It is also used for many popular content management systems andother scripts.

Learn more about what is MS SQL on its official website. They havecomprehensive learning material. You should also check out the SQL tutorial on

W3Schools and some articles on the SQL Community Server blog.

2. PostgreSQL

What is PostgreSQL?

PostgreSQL is a web hosting database that is used to store web site information

like blog posts or user information. PostgreSQL is a very popular relationaldatabase used on the web. This is partly because it completely free but it also has

some features that that other databases, like, MySQL, don't have.

What is PostgreSQL capable of?

In basic terms, PostgreSQL is capable of storing any type of that you want. You

can easily store and retrieve information using SQL statements. It also,importantly, allows multiple web site visitors to use it at once. In more technicalterms, PostgreSQL has the following features:

Functions

Indices

Triggers

MVCC

Rules

Wide variety of data types including unlimited length text, IPv4 and IPv6addresses, arrays, and XML

User-defined object

Inheritance

Sub-selects

Transactions

Full, inner, and outer joins

Views

Referential integrity

Tablespaces

Regular expressions

What is a PostgreSQL database used for?

PostgreSQL is used by several different web programming languages includingPHP, and Python. These programming languages make is extremely easy toconnect to a PostgreSQL database. It is also used for many content management

scripts.

What is phpPgAdmin?

Databases can be difficult to manage using just individual SQL statements. It ismuch easier to manage a database using a graphical user interface (GUI). One of

the best and most popular GUIs formanaging a PostgreSQL database is called

phpPgAdmin. It is a web-based application that makes it easy to manage yourPostgreSQL database. phpPgAdmin will let you add, remove and managedatabases, tables, and entries; backup the database, run specific SQL queries,

search and import record, and much more. Learn more about what is phpPgAdmin

from its official website.

3. Oracle Database

The Oracle Database (commonly referred to as Oracle RDBMS or simply

as Oracle) is an object-relational database management

system (ORDBMS) produced and marketed by Oracle Corporation.

Larry Ellison and his friends, former co-workers Bob Miner and Ed Oates, started

the consultancy Software Development Laboratories (SDL) in 1977. SDL

developed the original version of the Oracle software. The name Oracle comes

from the code-name of a CIA-funded project Ellison had worked on while

previously employed by Ampex.

Database "features":-

Apart from the clearly defined database options, Oracle databases may includemany semi-autonomous software sub-systems, which Oracle Corporation

sometimes refers to as "features" in a sense subtly different from the normal usageof the word. For example, Oracle Data Guard counts officially as a "feature", butthe command-stack within SQL*Plus, though a usability feature, does not appear

in the list of "features" in Oracle's list. Such "features" may include (for example):

Active Session History (ASH), the collection of data for immediate monitoringof very recent database activity.

Automatic Workload Repository (AWR), providing monitoring services toOracle database installations from Oracle version 10. Prior to the release ofOracle version 10, the Statspack facility[70]provided similar functionality.

Clusterware Data Aggregation and Consolidation Data Guard for high availability Generic Connectivity for connecting to non-Oracle systems. Data Pump utilities, which aid in importing and exporting data and metadata

between databases

Database Resource Manager (DRM), which controls the use of computingresources.

Fast-start parallel rollback Fine-grained auditing (FGA) (in Oracle Enterprise Edition) supplements

standard security-auditing features

Flashback for selective data recovery and reconstruction iSQL*Plus, a web-browser-based graphical user interface (GUI) for Oracle

database data-manipulation (compare SQL*Plus) Oracle Data Access Components (ODAC), tools which consist of:

5/11

Oracle Data Provider for .NET (ODP.NET) Oracle Developer Tools (ODT) for Visual Studio Oracle Providers for ASP.NET Oracle Database Extensions for .NET Oracle Provider for OLE DB Oracle Objects for OLE Oracle Services for Microsoft Transaction Server

Oracle-managed files (OMF) -- a feature allowing automated naming, creationand deletion of datafiles at the operating-system level.

Recovery Manager (rman) for database backup, restoration and recovery SQL*Plus, a program that allows users to interact with Oracle database(s)

via SQL and PL/SQL commands on a command-line. Compare iSQL*Plus.

Universal Connection Pool (UCP), a connection pool based on Java andsupporting JDBC, LDAP, and JCA

Virtual Private Database (VPD), an implementation of fine-grained accesscontrol.

4.Microsoft Access

Microsoft Office Access, previously known as Microsoft Access, is a databasemanagement system from Microsoft that combines the relational Microsoft Jet

Database Engine with a graphical user interface and software-development tools. It

is a member of the Microsoft Office suite of applications, included in the

Professional and higher editions or sold separately. On May 12, 2010, the current

version of Microsoft Access 2010 was released by Microsoft in Office 2010;

Microsoft Office Access 2007 was the prior version.

MS Access stores data in its own format based on the Access Jet Database Engine.

It can also import or link directly to data stored in other applications and databases.

Software developers and data architects can use Microsoft Access to

develop application software, and "power users" can use it to build software

applications. Like other Office applications, Access is supported by Visual Basic

for Applications, an object-oriented programming language that can reference a

variety of objects including DAO (Data Access Objects), ActiveX Data Objects,

and many other ActiveX components. Visual objects used in forms and reports

expose their methods and properties in the VBA programming environment, and

VBA code modules may declare and call Windows operating-system functions.


6/11

Features

Users can create tables, queries, forms and reports, and connect them together

with macros. Advanced users can use VBA to write rich solutions withadvanced data manipulation and user control. Access also has report creation

features that can work with any data source that Access can "access".

The original concept of Access was for end users to be able to "access" data from

any source. Other features include: the import and export of data to many formats

including Excel, Outlook , ASCII, dBase, Paradox, FoxPro, SQL

Server, Oracle, ODBC, etc. It also has the ability to link to data in its existinglocation and use it for viewing, querying, editing, and reporting. This allows the

existing data to change while ensuring that Access uses the latest data. It can

perform heterogeneous joins between data sets stored across different platforms.Access is often used by people downloading data from enterprise leveldatabases for manipulation, analysis, and reporting locally.

There is also the Jet Database format (MDB or ACCDB in Access 2007) whichcan contain the application and data in one file. This makes it very convenient to

distribute the entire application to another user, who can run it in disconnected

environments.

One of the benefits of Access from a programmer's perspective is its relative

compatibility with SQL (structured query language)queries can be

viewed graphically or edited as SQL statements, and SQL statements can be useddirectly in Macros and VBA Modules to manipulate Access tables. Users can mix

and use both VBA and "Macros" for programming forms and logic andoffers object-oriented possibilities. VBA can also be included in queries.

Microsoft Access offers parameterized queries. These queries and Access tables

can be referenced from other programs like VB6 and .NET through DAO or ADO.From Microsoft Access, VBA can reference parameterized stored procedures viaADO.

The desktop editions of Microsoft SQL Server can be used with Access as an

alternative to the Jet Database Engine. This support started with MSDE (MicrosoftSQL Server Desktop Engine), a scaled down version of Microsoft SQL Server

2000, and continues with the SQL Server Express versions of SQL Server 2005and 2008.

Microsoft Access is a file server-based database. Unlike clientserver relationaldatabase management systems (RDBMS), Microsoft Access does notimplement database triggers ,stored procedures, or transaction logging. Access

2010 includes table-level triggers and stored procedures built into the ACE dataengine. Thus a Client-server database system is not a requirement for using stored

procedures or table triggers with Access 2010. Tables, queries, Forms, reports and

Macros can now be developed specifically for web base application in Access2010. Integration with Microsoft SharePoint 2010 is also highly improved.

5. IBM DB2

IBM DB2 is a relational model database server developed by IBM. There are three

DB2 products that are very similar, but not identical: DB2 for LUW (Linux, Unix,

and Windows), DB2 for z/OS (mainframe), and DB2 for iSeries

(formerly OS/400). The DB2 LUW product runs on multiple Linux and UNIX

distributions, such as Red Hat Linux, SUSE Linux, AIX, HP/UX, and Solaris, andmost Windows systems. DB2 also powers the IBM InfoSphere Warehouse edition,

which is basically DB2 LUW with DPF (Database Partitioning Feature), a massive

parallel share-nothing data warehousing architecture. Alongside DB2 is

another RDBMS: Informix, which was acquired by IBM in 2001.

Features that benefits to any business include:-

When compared to running on DB2 9, depending on the workload, customersmay experience reduced CPU utilization

When compared to running DB2 9, up to five to ten times more concurrentusers on a single subsystem by avoiding memory constraints

Greater concurrency for data management, data definition, and data access,including DDL, BIND, REBIND, PREPARE, utilities, and SQL

Additional online changes for data definitions, utilities, and subsystems Improved security with better granularity for administrative privileges, data

masking, and audit capabilities

Temporal or versioned data to understand system and business times at thedatabase level (Bi-temporal feature is not available on Oracle or any other

competing RDBMS products)

pureXML and SQL enhancements to simplify portability from other databasesolutions

Productivity improved for database administrators, application programmers,and systems administrators

QMF Classic Edition, an optional for-charge feature, providing greaterinteroperability with other programs plus improved queries, forms, diagnostics,

performance, and resource control

6. Mysql

MySQL is the world's most popular open source database software, with over 100

million copies of its software downloaded or distributed throughout it's history.

With its superior speed, reliability, and ease of use, MySQL has become the

preferred choice for Web, Web 2.0, SaaS, ISV, Telecom companies and forward-

thinking corporate IT Managers because it eliminates the major problems

associated with downtime, maintenance and administration for modern, online

applications.

Many of the world's largest and fastest-growing organizations use MySQL to save

time and money powering their high-volume Web sites, critical business systems,

and packaged softwareincluding industry leaders such as Yahoo!, Alcatel-

Lucent, Google, Nokia, YouTube, Wikipedia, and Booking.com.

The flagship MySQL offering is MySQL Enterprise, a comprehensive set of

production-tested software, proactive monitoring tools, and premium support

services available in an affordable annual subscription.

MySQL is a key part of LAMP (Linux, Apache, MySQL, PHP / Perl / Python), the

fast-growing open source enterprise software stack. More and more companies are

using LAMP as an alternative to expensive proprietary software stacks because of

its lower cost and freedom from platform lock-in.

MySQL was originally founded and developed in Sweden by two Swedes and a

Finn: David Axmark, Allan Larsson and Michael "Monty" Widenius, who had

worked together since the 1980's

Features

As of April 2009, MySQL offered MySQL 5.1 in two different variants: the opensource MySQL Community Server and the commercial Enterprise Server. MySQL5.5 is offered under the same licences.They have a common code base and include

the following features:

A broad subset of ANSI SQL 99, as well as extensions
