Evolution Towards Strategic Applications of Databases through Composite Information Systems

Evolution towards Strategic Applications of Databases through Composite Information Systems

Many important strategic applications involve inter-corporate linkage or intra-corporate integration of information. This requires multiple databases to work together. We refer to this category of information systems as Composite Information Systems (CIS). Migrating from separate systems to a more fully integrated CIS environment is usually a difficult, expensive, and timeconsuming process both...

Towards Computational Neural Systems through Developmental Evolution

Beyond strategic information systems: towards an IS capability

The evolution of information technology (IT) in organizations is often portrayed as following three eras—Data Processing, Management Information Systems, and Strategic Information Systems (SIS)—each displaying distinct characteristics regarding the application of IT and having different objectives. While investments in IT continue to made for both efficiency and effectiveness purposes, the SIS ...

Implementing Strategic Information Systems

This paper presents a framework for the implementation of strategic information systems. The framework draws on past research on implementation and takes into account the unique circumstances of strategic applications. The framework is illustrated with a case study of a money-center bank's cash management system based on a microcomputer. The microcomputer provides a powerful front end to the ba...

How Strategic are Strategic Information Systems?

There are many examples of information systems which are claimed to have created and sustained competitive advantage, allowed beneficial collaboration or simply ensured the continued survival of the organisations which used them These systems are often referred to as being 'strategic'. This paper argues that many of the examples of strategic information systems as reported in the literature are...
