Database Management Library (DBL) is a relational database management system (RDBMS) contained in a C++ programming library. The DBL source code is available under the terms of the GNU General Public License. DBL was fully developed within two weeks, as a holiday programming project. It aims to be easy and simple to use for C++ programming.
A relational database (RDB [1]) is a database based on the relational model of data, as proposed by E. F. Codd in 1970. [2]A Relational Database Management System (RDBMS) is a type of database management system that stores data in a structured format using rows and columns.

Supports data durability via snapshots and journal logging, and high availability via a hot-standby.
Paradox for Windows applications are programmed in a different programming language called ObjectPAL. [3] Although key features of the DOS product, the QBE and the database engine, were ports keeping the DOS code, there was a major break in compatibility from PAL to ObjectPAL and in the shift to a GUI design metaphor for Forms and Reports. The ...
dBase is an application development language and integrated navigational database management system which Ashton-Tate labeled as "relational" but it did not meet the criteria defined by Dr. Edgar F. Codd's relational model. "dBASE used a runtime interpreter architecture, which allowed the user to execute commands by typing them in a command ...
[2] [3] [4] The MICRO Relational Database Management System which was implemented in 1970 was based on Childs' Set-Theoretic Data Structure (STDS) work. [citation needed] In 1970 Codd in his key paper on relational databases, A Relational Model of Data for Large Shared Data Banks, cited one of Childs' 1968 papers as part of the basis for the ...
LibreOffice Base is a free and open-source database development and administration tool for relational database management systems that is part of the LibreOffice office suite. LibreOffice Base was built off of a fork of OpenOffice.org and was first released as version 3.4.0.1 on October 4, 2011.
