The Excel

Wednesday, 3. July 2019

Space-enabled computers, so MPM systems were the target platform. Against this background, it was decided to develop its own database. The two young computer scientists appealed to the challenge in a real and challenging work to demonstrate their computer skills, that was dear to them, “as the program any functions in accounting”, Sartori recalls. They went with vigor the work. Started in January 1982.

Half a year later, in July 1982, the database programmed in basic was done. This pre-release was transferred in 1983 in the “C” programming language and thus made available for UNIX systems. This could be worked the next ten years, small fixes and improvements included. At that time spoke no relational or object-oriented databases. At the beginning of the eighties the relational databases on the market began to enforce.

What the two have developed, possessed many basic elements, currently assigned to the object-oriented database be. A foundation that turns out today, many years later, as beneficial and that still remains a stable basis for the implementation of modern requirements. The protected data bank – guarantor of the upgradeability of the traditional ERP systems usual separation between application and database layer has been replaced by a consistent integration of these two levels. This means: read and write access to the data are done about the for the respective objects (sales, customer, article, etc.) defined object methods. This decision was made very early and consistently solid. The record together with the methods that he knows make the abas object. The abas object method ensures a consistent database. This advantage becomes even clearer when one considers these two layers, so the application and database layer, the opposite concept of separation, how it is implemented in relational databases. Simplified one can imagine this interaction with the help of Excel. The Excel file is the database. Here there are many of the tables in which the data are, for example, two with the customers and orders.
