Founding the Future
Like a lot of technologies in the computer industry, the foundations of relational databases can be tracked back to IBM in the 1960s and 70s, and their research into automating office functions. ...
In 1970 an IBM researcher named Ted Codd published the first article on relational databases. ... The language created by the System R group, SQL (Structured Query Language) has become the industry standard for relational databases and is now an ISO standard. ...
The first databases systems built upon the SQL standard started to appear at the beginning of the 1980s from Oracle with Oracle Version 2, and later SQL/DS from IBM, as well as a host of other systems from other companies. ...
Evolution
The software of relational databases was continually refined during the 1980s. ...
Since their arrival, databases have expanded in size from the 8MB of data that System R had been tested with, to terabytes of data for mailing lists, customer information for retail stores and so on. ...
Object Oriented

This led to research being started in object oriented databases where users could define their own methods of access to data and how it was represented and manipulated.
