MOTIVATION
• Old needs:
Initially, the goal of information systems were to gather information
about a specific domain to support decision making.
nowadays, computerised organisations with transactional software applications
have specialised information systems towards a different goal :
to support the basic processes in an organisation (sales, production, personnel,…).
Information Systems nowadays are specialised for transactional work.
* So are database models, database design methodologies,
database management systems, etc.
These systems are not adequate for analysing the information
or to convey strategic knowledge.
• Inappropriate organisation/architecture
• Lack of information-to-knowledge tools.
