Different data storage built on ERP objects

Abstract

The ERP systems use tables for storing configuration and application data. The application data consist of master- and transactional data. When an HR expert would like to read employee data, the programs should read many corresponding master data tables and in some cases transactional tables as well. Afterwards the application builds up the employee object and the corresponding objects, like absences, qualifications, etc. Another example could be an invoice object, which contains the item objects and the invoice can be approved, rejected, parked, etc. The running systems are using object oriented thinking, but they convert the data from tables into object or vice versa.
