It is very important for database management system (DBMS) users to make sure there is illustration of the logical view of data using a precise data model; it includes hierarchical, network and relational models. The commercially available DBMS are based on the models but the relational product seems to have overshadowed other models. There is an effort been made to break the monopoly of the relational model which resulted in new data models like Object-oriented data model, Entity-Relationship data model, Functional data model, and Semantic data model. Also, an advance in the area of networking has given rise to database servers and its descendant, distributed databases. With this development, geographically distributed organization has its communication bills reduced significantly. For future research, database development tools may depend on the involvement of programming language researchers in databases, the impact of the object technology on the dominating relational model and whether the attempts to integrate knowledge and data bases ultimately yield commercially affordable products.
