Object Database Management Systems

Object DBMS take a real-world approach to the definition and storage of data. These systems emulate the environments in which stored objects exist. For example, objects that could be part of an object DBMS for accident investigations include accidents, incidents, airplanes, and crews. Within the system, it is very easy to create and maintain connections between related objects, and most object DBMS can accommodate complex data types, such as video images, pictures, and documents.

Although object DBMS are very good for storing complex objects, they are more difficult to use than relational DBMS because they usually cannot be accessed through a simple query language. In addition, these systems are not well suited to environments that have to support large numbers of users and large numbers of queries.
