On the Mathematics of Modelling, Metamodelling, Ontologies and Modelling Languages

Computing as a discipline is maturing rapidly. However, with maturity often comes a plethora of subdisciplines, which, as time progresses, can become isolationist. The subdisciplines of modelling, metamodelling, ontologies and modelling languages within software engineering e.g. have, to some degree, evolved separately and without any underpinning formalisms. Introducing set theory as a consistent underlying formalism, Brian Henderson-Sellers shows how a coherent framework can be developed that clearly links these four, previously separate, areas of software engineering. In particular, he shows how the incorporation of a foundational ontology can be beneficial in resolving a number of controversial issues in conceptual modelling, especially with regard to the perceived differences between linguistic metamodelling and ontological metamodelling. An explicit consideration of domain-specific modelling languages is also included in his mathematical analysis of models, metamodels, ontologies and modelling languages. This encompassing and detailed presentation of the state-of-the-art in modelling approaches mainly aims at researchers in academia and industry. They will find the principled discussion of the various subdisciplines extremely useful, and they may exploit the unifying approach as a starting point for future research.

In much of software engineering and conceptual modelling, such a
representation is through the application of a graphically based modelling
language (ML)—a language appropriate for each of the three domains shown in
Fig. 1.10 (see Fig. 6.1). Such an artificial language has many of the attributes of a
natural language in terms of possessing both syntax and semantics. Together
these form the specification or definition of the modelling language. The
modelling language can then ...

How to Specify Your Software Requirements

If you are a non-technical person with a stake in the success of a software project, this book is for you. Business managers often find it impossible to communicate business objectives and specify their software requirements to technical members of staff. This beginner's guide teaches readers to communicate with software developers in a more focused, effective way. It describes the basic diagrams of the UML modeling notation and shows how they are used to specify requirements in a unambiguous way. When used on project, the risk of failure through unclear requirements is removed.
