Sage-ST TMA GENERAL OVERVIEW |
Sage-ST TM refers to the actual set of packages and procedures containing the Ada code. Sage-ST TM contains libraries of reusable code for the Ada programmer to provide database and other capabilities for inclusion within an application system.
The Sage-ST TM system offers capabilities in many areas. An application may require the use of one or more of these. The application developer chooses only the capabilities required for a system and imports them from the packages in which they reside. These packages supplied with Sage-ST TM offer capabilities from the basic, such as string manipulation and terminal I/O, to the complex, such as database and window manipulations. Some of the capabilities available are presented in Table 1.
The application being developed within the Sage-ST TM environment will have unique requirements that are not satisfied by any of the packages of the Sage-ST TM system. The developer's solutions to these requirements, along with the programming code necessary to import and use the Sage-ST TM utilities, constitute the "programmed application." The final, completed system will, therefore, include the DFL file produced by the THOR editor, the required Sage-ST TM utilities, and the programmed application (see figure).
