Re: Oracle Forms
Oracle Forms (part of the Oracle Developer Suite - formerly Developer 2000 or D2K) is a Rapid Application Development (RAD) environment for developing database applications. The language used inside is PL/SQL.
Oracle Forms is able to access the Oracle database and generate a default form that presents the data. The form is compiled into an executable (fmx), that is run by the forms runtime module. The form is used to view and edit data in business applications. Various GUI elements, such as buttons, menus, scrollbars, and graphics can be placed on the form. The environment notably supplies built-in record creation, query, and update modes, each with its own default data manipulations. This eliminates the need to program common and tedious operations, such as creating dynamic SQL, sensing changed fields, and locking rows. As is normal with event driven interfaces, the software implements a complex algorithm, consisting of special functions called triggers, which occur at critical steps in the processing of records, the receipt of keyboard strokes, and the receipt of mouse movements. Different triggers are called before, during, and after each critical step. Each function is initially a stub, containing a default action or nothing. Programming Oracle Forms therefore generally consists of modifying the contents of these triggers in order to alter the default behavior. Some triggers, if provided by the programmer, replace the default action, others augment it. As a result of this strategy, it is possible to create a number of default form layouts which possess complete database functionality yet contain no programmer-written code at all.
