In addition, since the modeling reflects real business use,
application performance may improve as objects are built that do not require excessive
manipulation to conform to the real-world behavior of the business processes
they represent.
Oracle chose to take an evolutionary approach to object technology by allowing data
abstraction, or the creation of user-defined datatypes as objects and collections as
extensions to the Oracle relational database. The Objects and Extensibility features,
included with the database since Oracle8i, position Oracle as an object-relational
database.
Support of the Java language complements this approach. The JVM (formerly
JServer) feature is a Java Virtual Machine integrated with the database. It supports
the building and running of Java components, as well as Java stored procedures and
triggers, in the server.
Object-Relational Features
This section describes the major object-relational features available in Oracle.
Objects in Oracle
Objects created in Oracle are reusable components representing real-world business
processes.
