"A relational database matches data using common characteristics found within the data set. The resulting groups of data are organized and are much easier for people to understand. In such a database the data and relations between them are organised in tables. A table is a collection of records and each record in a table contains the same fields. Certain fields may be designated as keys, which means that searches for specific values of that field will use indexing to speed them up.

"The term relational database was originally defined by Edgar Codd, a British computer scientist, whilst working at IBM Almaden Research Center. He recognised that the concept of a relational database could be derived from the principles of relational algebra and relational calculus.

"A Relational Database Management System (RDBMS) is a Database Management System (DBMS) that is based on the relational model. Most database systems today are based on this type of system.
