There are lot of Database Management systems that run on Linux, but MySQL and PostgreSQL seem to be the mostly used Database Management systems.
DB2 is a family of relational database management system (RDBMS) products from IBM that serve a number of different operating system platforms. According to IBM, DB2 leads in terms of database market share and performance. Although DB2 products are offered for UNIX-based systems and personal computer operating systems, DB2 trails Oracle's database products in UNIX-based systems and Microsoft's Access in Windows systems.
Oracle database is the first database management system based on the System-R model of IBM and the first relational database that uses SQL. Though it supports various operating systems.
differences between document management and database technology
There are currently 3 general categories of data base management systems in use today:relational database systemsmultidimensional database systems (often referred as 'cubes')object oriented database systemsPrior to the success of relational database systems (early 80's) there were also hierachical database systems and network (aka CODASYL) database systems.
database management systems
Database management systems are typically used for organizing data within a database. The data is organized so that it can be retrieved and stored in the most efficient manner possible.
A collection of programs that allow a user to extensively modify, store, and extract information from a database is called a database management system. Also knows as "DBMSs," these systems vary in size and function. They range from those operating on personal computers to mainframe-based systems utilized solely by large companies. Examples include Oracle, RDBMS, dBase Clipper and FoxPro.
There are four basic and main database management systems that are used today. Those four include hierarchical, network, relational and object-oriented.
A large number of database management systems (DBMS) exist. For example: Oracle, MySQL, DB2.

DBMS stands for "Database Management Systems" it includes all Databases. RDBMS are a special Type of DMBS. "Relational Database Management Systems". On RDBMS you have Tables. Some Tables have are in relation to other Tables. This is needed to organize complex Data. Systems like MySQL, MS Access or MS SQLServer are RDBMS. Other Types are: ODBMS - Object Database Management System ORDBMS - Object Relational Database Management System HDBMS - Hirarchical Database Management System NDBMS - Network Database Management System
Usually, "database management systems" are referred to Relational Database Management System. Types include: Microsoft SQL Server Oracle MySQL (along w/ a myriad of open source products) These differ from flat file databases such as FoxPro, MS Access, etc.
