Data supply for computer cores

The computer cores enable two different types of call. On the one hand, individual contract data such as deadlines or premiums can be queried, on the other, a contract can be recalculated and changed using the currently available data. For these calls, the computer cores need to be supplied with data from the inventory database. As the database and computer core have different formats, the data has to be converted functionally (e.g. translation of one number range to another) and enriched with data from other systems (e.g. with previous contract data from a web service). The data supplies and computer core calls take place both on the case handler computer and in host batch mode. Each method has its own data supply. The programs on the client and in the rest of the application are implemented in Java, while on the host they are implemented in C++. As different processes are supported on the client and on the host, there are only partial overlaps.
