Requirements Engineering for Transactional Systems

The book starts with failure statistics of transactional systems and the technological responses for failure mitigation. We discuss the evolution of development processes for transactional systems and highlight the emerging role of agile development. This mitigates failure through iterative and incremental development. The second response is to focus on system requirements. Here we first define the term requirements and consider the requirements engineering process. The approaches to requirements elicitation are reviewed. This lays the basis for the next chapter so as to discuss the differences between transactional and data warehouse requirement engineering respectively.
