In this chapter, you will see details on the use of object types. This chapter covers topics including security administration for object types and the indexing of object type attributes. The creation of methods for object types is also shown, along with the use of object views and INSTEAD OF triggers.
To use the information provided in this chapter, you should be familiar with datatypes (see Chapter 5), views (see Chapter 17), the grant command (see Chapter 20), indexes (see Chapter 17), and PL/SQL procedures and triggers (see Chapters 32, 34, and 35). Elements of each of these topics play a part in the implementation of an object-relational database.
