Database management systems are used to store and to access information.
In the Relational Database Management System (RDBMS), all the data is in the form of simple columns and rows in a table. Structured Query Language (SQL) is is the standard query language for RDBMS. Some of the disadvantages of RDBMS are: not enough storage area to handle data such as images, digital and audio/video, do not provide good support for nested structures,not much efficient and effective integrated support.
The term object oriented database management systems (OODBMS) refers to a wide variety of different database technologies that were developed in order to overcome some of the limitations of relational databases.
