Part 2: PART II Advanced PL/SQL Features > Objects in the Database
Chapter 15. Objects in the Database
In Chapter 14 we discussed object-oriented programming and introduced object types and object instances. The focus of the chapter was on transient objects, or objects that exist only in the context of program execution. In this chapter we extend the objects discussion to persistent objects, or objects that exist after program execution, such as object tables and object views. You will also learn how to use DML and built-in functions with objects, and explore type evolution with persistent objects.
NOTE
If you are unfamiliar with object type creation, inheritance, type evolution, and differences between transience and persistence, it is highly recommended that you read Chapter 14 before reading this chapter.
