OBS is based on Client/Server-architecture:

• The user workstation can be any version of Windows-95/Windows-98/Windows-NT/Windows2000/Windows-XP/Vista
• The server can be one of multiple systems, e.g. UNIX-(SunSolaris, HPTrue64, Linux) or Open-VMS as well as IBM AS400

As opposed to many other Core Banking Systems, OBS was specifically developed to be hardware independant, thus giving the client more flexibility and choice. The flexible archtitecture that characterises OBS allows for a rapid adaption to other or new hardware platforms without having to make any changes to the core system.

A modern relation database design coupled with the leading database company Oracle guarantees high performance, security and availability. With the use of market standard query tools (e.g. Business Objects) additional reports can be created quickly and easily.

All server programmes are standardised and written in structured Cobol, whereas the client modules are in Delphi. Adherence to stringent internal guidelines ensures high quality and low maintenance effort.
