Relational database management system

A relational database management system (RDBMS) is a database management system (DBMS) that is based on the relational database model.

Description

Many popular databases currently in use are based on the relational database model.

Popular database model

RDBMSs are a common choice for the storage of information in new databases used for financial records, manufacturing and logistical information, personnel data, and other applications since the 1980s.

Relational databases may be easier to understand and use than other database models, such as hierarchical databases and network databases.

Non-relational databases

Non-relational databases include:

• Object databases, which were introduced in an attempt to address the object-relational impedance mismatch in relational databases
• XML databases
