The database applications software environment commenced with programmers who attempted to encode the processes and rules of the operational organisation into some form of program development code, dependent upon the hardware platform. At the end of their programming project, a functional application would be available for the IT Management of the organisation to deploy. Invariably the database application software solution for any one organisation was not immediately responsive to change, due to its size and because its functionality had to be closely coordinated with the compatible functionality of the available hardware, its (proprietary) operating system, and its (proprietary) DBMS.
Once a database application had been first developed by a software vendor it could then be resold or relicensed to another organisation, perhaps with only minor modification if the organisations were similar. In this way, terrain by terrain, the organisational environment itself began to be mapped out by one or more specific database applications software packages. There emerged competition between application software code developers for the market of supply to organisations in every type of marketing sector imaginable: scientific, government and administrative, and all forms of business markets.
