Abstract

An object-oriented database manages its data (i.e., the so-called objects) according to an object-oriented data model. An object encapsulates both state and behavior and has a unique object identity. Objects are instantiated from classes that may be organized in hierarchies with inheritance. Related to inheritance are the concepts of dynamic binding, polymorphism, overriding, and overloading.
