For the spirit of the IT solution, it is important how the author looks at the world of today and assesses the needs of how and how much to be informed. The solution lies in how we apprehend the ability of the IT-world to adapt to the factual as well as to technological changes, which are still going on around us. Our "swing to accept" the variability of the world we operate in, guarantees our set-up for these changes. It is the basis for finding solutions which among others emphasise the architecture, the interface and technologies based on open standards.
The IT solutions we supply our customers are built on available top-technologies provided, it guarantees the required level of stability and security. The choice of the technology is more and more influenced by its compatibility with the increasing number of technical standards. This requirement enables future flexibility for our solutions. The customer appreciates it even at the moment of the changes or when the communication with other IT systems is required.
Except for the usage of available technologies, we also develop our own ones; Mainly for cases when the technology market does not offer a suitable solution. Currently this concerns mainly technologies using the latest XML standards.

Architecture
The architecture of our systems are based on the co-existence of our own components in a heterogeneous environment; which were developed by our customers in previous history as a result of internal as well as external influences. Therefore we emphasise the architecture based on SOA-services. This enables connection of the most variable components of the heterogeneous IT environment: those already existing but those future ones as well.
