Summary
In this chapter, you learned about different ways in which objects are useful in Oracle. In particular, you learned about three different ways in which objects are useful:
-
Purely as a programming construct
-
As a mechanism to store data in object tables
-
In the form of object views that work on top of relational tables
You discovered that it is best to use objects as a programming construct to enhance the power of your PL/SQL code. Storing data in object tables that contain varrays or nested table columns can lead to complex code that does not perform well, as you learned from the performance study done at the end of the chapter. In particular, you discovered that DMLs on relational tables perform much better in general when compared to DMLs carried out on object views and tables containing nested tables. In the next chapter, we will look at how to access objects from JDBC.
