*RELATIONAL DATABASE MANAGEMENT SYSTEM*
.
.
‘connolly’ + ‘begg’ define ‘Database Management System’ (DBMS) as…
*”software system that enables users to define, create, maintain and control access to the ‘database’*
(who are ‘connolly’ + ‘begg’?)
.
RDBMS is an extension of that acronym that is sometimes used when the underlying database is ‘relational’
.
An alternative definition for a relational database management system is a database management system (DBMS) based on the relational model.
Most databases in widespread use today are based on this model
RDBMSs have been a common option for the storage of information in databases used for financial records, manufacturing and logistical information, personnel data, and other applications since the 1980s.
Relational databases have often replaced legacy hierarchical databases and network databases, because RDBMS were easier to implement and administer.
Nonetheless, relational databases received continued, unsuccessful challenges by object database management systems in the 1980s and 1990s,
(which were introduced in an attempt to address the so-called object–relational impedance mismatch between relational databases and object-oriented application programs),
as well as by XML database management systems in the 1990s
.
However, due to the expanse of technologies – such as horizontal scaling of computer clusters, NoSQL databases have recently become popular as an alternative to ‘RDBMS databases’*
