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 .

In database theory, a relation, as originally defined by E. F. Codd, [1] is a set of tuples (d 1,d 2,...,d n), where each element d j is a member of D j, a data domain. Codd's original definition notwithstanding, and contrary to the usual definition in mathematics, there is no ordering to the elements of the tuples of a relation.
"Ramis is a compromise 4GL relational database management system. It lacks SQL, a full programming language, good tech support, and the brute-force capabilities and sophistication of its competition. But it's remarkably easy to learn and use, comes with decent documentation, and performs the database basics."
4D (4th Dimension, or Silver Surfer, as it was known during early development) is a relational database management system and integrated development environment developed by Laurent Ribardière. [ 3 ] 4D was created in 1984 [ 4 ] and had a slightly delayed public release for Macintosh in 1987 [ 5 ] [ 6 ] [ 7 ] with its own programming language .
The first is the problem of evaluating a conjunctive query on a relational database where both the query and the database are considered part of the input. The complexity of this problem is usually referred to as combined complexity , while the complexity of the problem of evaluating a query on a relational database, where the query is assumed ...
The relational model (RM) is an approach to managing data using a structure and language consistent with first-order predicate logic, first described in 1969 by English computer scientist Edgar F. Codd, [1] [2] where all data are represented in terms of tuples, grouped into relations.
