The customer uses Endur energy trading software as well as a planning database created in-house based on MS Access. Data must be transferred from Endur to this database in order to support planning. For this purpose, PTA must first develop a new concept by means of which technical utilities can store the data in Endur and then transfer it, making the data susceptible to maintenance. Following that, and according to the concept, a prototype is developed which provides the best basis for specific implementation of the measure. Storage of data in Endur is carried out using UDWs (user data worksheets), while the data is transferred via SQL and corresponding views are created.
