Abstract: A compilable application program generator (100) comprises a graphical user interface (150) with a document creator (155) and a process flow charter (160). Each document used in a business operation is recreated electronically with the document creator (155), and the process flow of each of the recreated documents in the business operation is modeled with the process flow charter (160). Recreating the documents includes providing user specifications (105) and document process flow specifications (120). The document creator (155) and the process flow charter (160) use the provided user specifications (105) and produce definitions that stored in the memory (170). Predetermined data processing definitions are subsequently used by a data processing program generator (175) to produce a compilable data processing program module (130). Similarly, a report program generator (185) produces a compilable report program module (135) using predetermined report definitions.
