An object-oriented operating system [1] is an operating system that is designed, structured, and operated using object-oriented programming principles. An object-oriented operating system is in contrast to an object-oriented user interface or programming framework, which can be run on a non-object-oriented operating system like DOS or Unix .
Both object-oriented programming and relational database management systems (RDBMSs) are extremely common in software today. Since relational databases do not store objects directly (though some RDBMSs have object-oriented features to approximate this), there is a general need to bridge the two worlds.
In object-oriented programming (OOP), an object is an abstract data type with the addition of polymorphism and inheritance. An object-oriented system integrates code and data as objects that each have state (data) and behavior (code). Any language that supports a construct with state and behavior is classified as object-based.
