 1. MySQL  is the world's second most  widely used open-source relational database management system (RDBMS).  It is named after co-founder Michael HYPERLINK ""Widenius's daughter, My. The SQL phrase stands for Structured Query Language. The default port of Mysql is 3306. The MySQL development project has made its source code available under the terms of the GNU General Public License, as well as under a variety of proprietary agreements. MySQL was owned and sponsored by a single forHYPERLINK "" HYPERLINK ""profitfirm, the Swedish company MySQL AB, now owned by Oracle Corporation.

2. PostgreSQL
PostgreSQL, often simply Postgres, is an open source object-relational database management system (ORDBMS) with an emphasis on extensibility and standards compliance. It is released under the PostgreSQL License, a free/open source software license, similar to the MIT License. PostgreSQL is developed by the PostgreSQL Global Development Group, consisting of a handful of volunteers employed and supervised by companies such as Red Hat and EnterpriseDB. It implements the majority of theSQL:2011 standard, is ACID-compliant, is fully transactional (including all DDL statements), has extensible updateable views, data types, operators, index methods, functions, aggregates, procedural languages, and has a large number of extensions written by third parties. PostgreSQL is available for many platforms including Linux, FreeBSD, Solaris, Microsoft Windows and Mac OS X. The vast majority of Linux distributions have PostgreSQL available in supplied packages. OS X, starting withLion, has PostgreSQL server as its standard default database in the server edition, and PostgreSQL client tools in the desktop edition.

3. SQLite is a relational database management system contained in a small (~350 KB) Cprogramming library. In contrast to other database management systems, SQLite is not a separate process that is accessed from the client application, but an integral part of it. SQLite is ACID-compliant and implements most of the SQLstandard, using a dynamically and weakly typed SQL syntax that does not guarantee the domain integrity. SQLite is a popular choice as embedded database for local / client storage in application software such as web browsers. It is arguably the most widely deployed database engine, as it is used today by several widespread browsers, operating systems, and embedded systems, among others. SQLite has many bindings to programming languages. The source code for SQLite is in the public domain

4. Oracle Database
The Oracle Database commonly referred to as Oracle RDBMS or simply as Oracle is an object-relational database management system  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.

5. dBASE database software was one of the first and in its day the most successful database management systems for microcomputers. The dBASE system includes the core database engine, a query system, a forms engine, and a programming language that ties all of these components together. dBASE's underlying file format, the .dbf file, is widely used in applications needing a simple format to store structured data. dBASE was originally published by Ashton-Tate for microcomputer operating system CP/M in 1980, and later ported to Apple II and IBM PC computers runningDOS. On the PC platform, in

6. FoxPro  was a text-based procedurally oriented programming language and DBMS, originally published by Fox Software and later by Microsoft, for MS-HYPERLINK...
