Migration from Relational Database into Object Oriented Database

Abstract

Object-Oriented Technology is an important discipline in the field of software engineering in general and it is, therefore, natural to ask whether it is relevant to the field of database management in particular and what that relevance is. There is, however, no consensus on answer to these questions. Some authorities believe that object oriented database systems will take over the world replacing relational system whereas others believe that they are suited only to certain very specific problems and will never capture more than a small fraction of the overall market. Object-Oriented technology represents real world very well, focusing on data rather than procedure and gives more security to data. Also, it is safe from unauthorized use of data because it provides three access specifiers viz. private, public and protected and strictly provides security to data in database. This technology also provides function as well as data together so that the data can be manipulated by the given function. In this paper, we show that how the data is more secure in object-oriented database than in relational database and also why do we migrate from RDBMS into OODBMS.
