Clipper compiler for windows11/7/2022 Written procedures for DBIII required in order to be executed that DBIII was installed on the target computer, and if I remember correctly DBIII costed one million and a half italian lire (compared to today, at least three or four thousand euro), the procedures were also simple text files and any scoundrel could have copied and reused them hidden from the rightful author. At the time there were just a few programmers and software, so the DBIII, which was infinitely more powerful, effective and easy than traditional programming languages, quickly gained a big market share. Soon enterprising programmers began to offer these procedures ready-made or customized to one’s needs, to a market in rapid expansion and practically virgin. In this way a company could buy the DBIII and then hire a programmer to design a whole management, perhaps by writing ad hoc procedures. It was also possible to present menus of choice and then fed to inexperienced users a comprehensive management program, such as an order management and billing, inventory, warehouse management, etc. It was therefore possible to use DBIII “directly” by giving one instruction at a time, or for repetitive tasks write to a file such instructions and then instruct DBIII to read the file and execute them sequentially. DBIII had its own programming language with dozens of specific instructions aimed at the database management. With DBIII, which is essentially a programmable database, it is possible to create in an easy and intuitive way databases, and also write procedures in a simple high-level language to manage them. In the mid 80s in the computer scenario the firm Ashton-Tate is one of main players among developers of business applications, experts and simple hobbyists.
