Evolving Information Systems: Beyond Temporal Information Systems
Nowadays, in order for an organisation to be competitive, it must be able to adapt quickly to its dynamic environment. In this paper, we discuss the need for information systems which are capable to evolve to the same extent as organisations do. Requirements of evolving organisations on their information systems are identified, followed by alternative approaches to adequate information systems development life cycles. We adopt an evolutionary approach resulting in so-called evolving information systems.
On the basis of requirements and an architecture for these evolving information systems, the distinction from traditional information systems is explained. Traditional information systems, including temporal information systems, appear to be degenerations of our evolving information systems. A conceptual framework for update in evolving information systems is derived from the requirements. An event level, a recording level and a correction level are distinguished in this framework for update.
