ORACLE and Progress Objects and Terminology
ORACLE and Progress databases share the structural elements common to relational databases, but each system has its own elements. These structural elements are called schema objects in ORACLE and database objects in Progress. Schema objects or database objects are components of the database’s logical structure. The two database management systems have different terminology for referring to these objects, as shown in Table 2–1.
