Discuss the main concepts of the ODMG Object Model. Give an example to illustrate each of the concepts.
What will be an ideal response?
The ODMG OM is a superset of the OMG OM and specifies the following basic modeling
primitives:
? The basic modeling primitives are the object and the literal. Only an object has a unique
identifier.
? Objects and literals can be categorized into types. All objects and literals of a given type
exhibit common behavior and state. A type is itself an object. An object is sometimes
referred to as an instance of its type.
? Behavior is defined by a set of operations that can be performed on or by the object.
Operations may have a list of typed input/output parameters and may return a typed
result.
? State is defined by the values an object carries for a set of properties. A property may be
either an attribute of the object or a relationship between the object and one or more
other objects. Typically, the values of an object’s properties can change over time.
? An ODMS stores objects, enabling them to be shared by multiple users and applications.
An ODMS is based on a schema that is defined in the Object Definition Language
(ODL), and contains instances of the types defined by its schema.
