Object Oriented Database Management Unit Iii Pdf In object based databases, each entity is treated as an object and represented in a table. similar objects are classified into classes and subclasses and the relationship between two objects is maintained using the concept of inverse reference. A distributed database is a database in which not all storage devices are attached to a common processor. it may be stored in multiple computers, located in the same physical location; or may be dispersed over a network of interconnected computers. There are two basic strategies for obtaining legitimate oids: register the objects with an authority.this strategy can be convenient, for example, if you need a small number of oids. obtain an arc (an arc is an individual subtree of the oid tree) from an authority and assign your own oids as needed. Object oriented database systems. the approach is heavily influenced by oo programming languages and can be understood as an attempt to add dbms functionality to a programming language environment.
