Further development of a computer core for a private health insurance

The previously used system for inventory management is being replaced by a new system, so the computer core of the new system has to support all tariffs and processes of the old system. For this purpose, it is necessary to expand the computer core of the new system to include very many functions, because in future it will have to be able to deal with all tariff types, all of the inventory contracts and all technical processes. The new system is distributed between different platforms. The case handler uses a Windows-based client for creating new contracts and changing contracts; contracts sent by external staff are processed by a Linux-based application server, and batch processes such as contribution adaptations and contribution refunds run on the host. The computer core is written in C++ because of the different platforms.
