Company information environment (which means data and applications working with these data) has to fully support company business processes. Outputs of these processes are the products (production sphere) or services (public administration institutions). Nevertheless the company development and external influences (e.g. customers behaviour, changes in data requirements, the impact of competition, the influence of suppliers, customers influence, legislation changes, etc.) lead into the processes changes, which are further reflected in demands on used information environment. The institutions (and their customers) need data from 'Classical' transactional systems and from geographic information systems (for spatial decision making). Requirements for changes of spatially oriented data are more frequent than requirements for changes in classical information systems.
