505			_aThe explosion in complex multimedia content makes it crucial for database systems to support such data efficiently. This paper argues that the "blackbox" ADTs used in current object-relational systems inhibit their performance, thereby limiting their use in emerging applications. Instead, the next generation of object-relational database systems should be based on enhanced abstract data type (E-ADT) technology. An (E-ADT) can expose the semantics of its methods to the database system, thereby permitting advanced query optimizations.
