This part shows you how to use the database you built in the previous exercises, introducing several important ObjectScript features. In the next exercises, you'll develop lookup/edit/delete methods.

You'll learn about core database features of ObjectScript.

• Functions: $Order, $Translate, $Replace, $Get, $Test.

• Commands: Lock, TStart, TCommit, TRollback.

• A little bit about objects, properties, and instance methods, including the standard object methods %New(), %OpenId(), and %Save().
