Historical Development of Database Technology


Historical Development of Database Technology

Early Database Applications

The Hierarchical and Network Models were introduced in mid 1960’s and dominated during the seventies. A bulk of the worldwide database processing still occurs using these models.

Relational Model based Systems

The model that was originally introduced in 1970 was heavily researched and experimented with in IBM and the universities. Relational DBMS Products emerged in the 1980’s.

Object-oriented applications

OODBMSs were introduced in late 1980’s and early 1990’s to cater to the need of complex data processing in CAD and other applications. Their use has not taken off much.

Data on the Web and E-commerce Applications

Web contains data in HTML (Hypertext markup language) with links among pages. This has given rise to a  new set of applications and E-commerce is using new standards like XML (eXtended Markup Language).
