Sample text

For all practical purposes, it is an object. The operations performed on that structured type instance by various procedures, functions, and methods (discussed in more detail in Chapter 4, "Routines and Routine Invocation") behave in the manner that an object system affects the objects in that system. 15, I explain SQL's object model and compare it to another well-known object model, Java's. The two principle characteristics of structured types in SQL:1999 are these: they normally have stored data associated with them; and the operations that can be performed on them are implemented by code provided by the type definer.

The answer (obvious to some, but not all, observers) was deceptively simple: build into SQL engines the capability to allow application builders to define their own specialized data types, especially including code to provide the semantics of those types. Some vendors used a pure SQL approach to providing this capability, while others used a hybrid approach that allowed SQL to invoke code written in another programming language, sometimes even supporting data types of that other language directly in the SQL engine.

Abstract data types (the ability to define classes of data comprising data structures and operations on them whose details are hidden from the users of the types), 2. Inheritance (the ability to share structure and behavior among related types), and 3. Object identity (the real-world characteristic that every entity is uniquely identifiable). The purposes of object orientation, they tell us, include improved modeling of the application's worldview and increased ability to reuse application code in other applications.
