A set of messages to which the object responds each message may have zero, or more parameters. Most of the object databases also offer some kind of query language, permitting objects to be found through a declarative programming approach.
Mandatory features: the Golden Rules
In some lodbms, we have to deal with complex data types. By registering the user defined aggregation function, query processing becomes easier. This feature guarantees harmonious coexistence among users. By allowing multiple transactions to run concurrently will improve the performance of the system in terms of increased throughout or improved response time.

This means that the user cannot see the inside of the object but can use the object by calling the program part of the object. By similar, we mean that they respond to the same message, use the same methods, and have variables of the same name and type.
