Our starting point will be to document and model the structure and processes of the organisation’s business. Starting from some description of the problem, the initial problem statement, you will learn how to identify elements of the real-world problem and their properties, and build corresponding structural and dynamic models. The emphasis at this stage is on understanding the current domain situation.
The behaviour model provides descriptions of business processes and behavioural aspects of the domain. You will meet modelling techniques such as activity diagrams. Business rules are used to express constraints on the dynamic model. For example, given a behaviour model describing aspects of a library, there might be a business rule determining the limit on the number of books an individual member can borrow. A structural domain model, also called the conceptual model, describes the significant concepts in the domain and how they are related.
A glossary of relevant terms and definitions is also produced. This textual document grows throughout the duration of the project.
Some artefacts involved in domain modelling (as well as some used in other phases) are shown in Figure 11.
