Chapter 8. Package Construction
Packages are the fundamental building blocks of any well-designed application built in the Oracle PL/SQL language (at least until Oracle improves the robustness of its object implementation!). A package consists of up to two elements: the specification and the body. The specification tells a user what she can do with the package: what programs can be called, what data structures and user-defined types can be referenced, and so on. The package body implements any programs in the package specification; it can also contain private (i.e., not shown in the specification) data structures and program units.
