This paper documents the transfer of 4GL applications from INGRES to ORACLE. As a result of a fast and conceptual change in computer languages, 4GLs were developed and evolved. These are programming support tools whose goal is, basically, to make the programs more efficient by reducing the number of instructions. Both ORACLE and INGRES database systems use 4GLs to develop applications. Their 4GL environments and their facilities for application development are investigated and explained in depth in this effort. The TWX application, which was originally implemented in INGRES by using its 4GL, is designed and reimplemented in ORACLE. This is accomplished in ORACLE SQL Forms. Totally eight forms are built to accommodate the new application. The data, itself, was easily transferred to ORACLE apriori. The TWX applications now runs on a Sun386i stand-alone computer interactively.
