Free database management system (DBMS). MySQL server is characterized by high speed, stability and ease of use, is the solution for small and medium-sized applications. In addition to Oracle Database is one of the fastest DBMS today. Distribution of MySQL database management system based on the GPL and high speed processing of requests has resulted in the database has become the de facto standard in network hosting services. Typically, MySQL is used as a server, which treated local or remote clients, but the distribution is a library internal server to include MySQL in the autonomous program, and perform sql queries. Flexibility DBMS MySQL supports a large number of types of tables: Users can choose vert fast table type MyISAM, supporting the full-text search, and a slow but very steady table InnoDB, supporting the transaction at the level of individual records. Moreover, the DBMS MySQL comes with a special type of table EXAMPLE, demonstrating the principles of creating new types of tables. Through an open architecture and the GPL-licensed, new types of tables are constantly created in the MySQL database management system.

MySQL Enterprise Server 5.1 delivers enterprise features, including:

• Partitioning to improve MySQL performance and management of very large database environments
• Row-based/Hybrid Replication for improved replication security
• Event Scheduler to create and schedule jobs that perform various database tasks
• XPath Support
• Dynamic General/Slow MySQL Query Log
• Performance/Load Testing Utility (mysqlslap)
• Full Text Search
• Archive engine (better compression, more features)
• User session and problem SQL identification
• MySQL embedded library (libmysqld)
• INFORMATION_SCHEMA objects
• Faster data import operations (parallel file load)
• ACID Transactions to build reliable and secure business critical applications
• Stored Procedures to improve developer productivity
• Triggers to enforce complex business rules at the MySQL database level
• Views to ensure sensitive information is not compromised
• Information Schema to provide easy access to MySQL metadata
• Pluggable Storage Engine Architecture for maximum MySQL flexibility
• Archive Storage Engine for historical and audit data

During installation on your computer will be installed three applications :

1) MySql Administrator – the software to administer a mysql database server.

2) MySql Query Browser – the software for the construction, execution and optimization of SQL queries.

3) MySql Migration Toolkit – software for the migration of your database in the MySql database server, creating a “snapshot” basis.

Microsoft MSSQL Server 2005 – relational DBMS (database management system) from Microsoft.
Microsoft SQL Server – is a complete sentence in the area of databases and data analysis for the rapid creation of scalable solutions e-commerce, business applications and data warehousing. MS SQL significantly reduces the time out of these solutions on the market, while ensuring scalability that meets the highest requirements. In SQL Server is to use XML language and protocol HTTP, a means of improving performance and availability to distribute the load and ensure smooth operation, features to improve the management and configuration, reduce total cost of ownership. In addition, SQL Server take full advantage of all opportunities operating system Windows, including support for up to 32 processors and 64 GB of RAM.
Microsoft SQL Server also supports Open Database Connectivity (ODBC) – the interface between application with the DBMS. The latest version (MS SQL Server 2005) enables users to connect through web services using the protocol SOAP. This allows the client program is not designed for Windows, cross platform to connect to MS SQL Server. Microsoft also released a certified driver JDBC, which allows applications that are developed on Java (such as BEA and IBM WebSphere) to connect to MS SQL Server 2000 and 2005.
In MS SQL Server 2005 has built support .NET Framework. Thus, the database stored procedures can be written in any language platform .NET, using the full set of libraries available to .NET Framework, including the Common Type System (system of data types in Microsoft .NET Framework). However, unlike other processes, .NET Framework, as a basic system for MS SQL Server 2005, provides more memory and build management tools MS SQL Server instead of using built-in Windows. This increases productivity compared with the general algorithms Windows, because the resource allocation algorithms specially configured for use in the structures of MS SQL Server.

Firebird (Firebird SQL) – a powerful, compact, cross platform, a free database management system (DBMS), provides the most complete support standard ANSI SQL, running on Linux, Windows and various Unix platforms.

Firebird is a database server. Powerful, but at the same time, with minimum requirements for setup and administration, Firebird easily scalable from single applications to large corporate systems. One Firebird server can handle several independent databases, each with multiple user connections. And, not least, Firebird is a true open source, completely free from royalties, even for commercial use.

Features:

• Firebird has full support of Stored Procedures and Triggers
• Firebird has full ACID compliant transactions
• Referential Integrity
• Multi Generational Architecture (sometimes called MVCC)
• Firebird has very small footprint
• Firebird has fully featured internal language for Stored Procedures and Triggers (PSQL)
• Support for External Functions (UDFs)
• Little or no need for specialized DBAs
• Almost no configuration needed – just install and start using
• Big community and lots of places where you can get free and good support
• Optional single file embedded version – great to create CDROM catalogs, single user or evaluation versions of applications
• Firebird includes dozens of third party tools, including GUI administrative tools, replication tools, etc.
• Careful writes – fast recovery, no need for transaction logs
• Firebird has many ways to access your database: native/API, dbExpress drivers, ODBC, OLEDB, .Net provider, JDBC native type 4 driver, Python module, PHP, Perl, etc.
• Native support for all major operating systems, including Windows, Linux, Solaris, Mac OS.
• Incremental Backups
• 64-bit builds available
• Firebird has full cursor implementation in PSQL
