Software engineering perspectives

In the previous chapter we looked at idioms and patterns that resulted from object-oriented software development. In this chapter we will focus on the software engineering of object-oriented systems and issues of design in particular, including the identification of objects and the specification of contractual obligations.

Software engineering perspectives

methods of development
the identification of objects
contracts -- refinement
validation -- a formal approach

Additional keywords and phrases: requirements, analysis, implementation, design as transition, CRC cards, responsibilities, heuristics, contractual obligations, validation

slide: Software engineering perspectives

First we will explore what methods are available to guide us in the development of object-oriented systems. Then we will look more closely at the heuristics of actual design. After establishing what is involved in specifying contractual obligations, we will discuss what is needed for a more formal approach to object-oriented development.
