This unit looks at two central principles of all engineering disciplines:
structure and reuse.
First we look at software architecture, which is concerned with software
elements, their externally visible properties (in other words their interfaces in
the widest sense) and their relationships (which include their interactions).
We then examine how architecture interacts with requirements and we shall
see that architecture and requirements evolve together and are closely
intertwined. A particular subset of requirements, which we describe as
architecturally significant requirements (ASRs), has a major influence on the
architecture of a system. We look at how different views can be used to
represent the system – focusing on the logical, process and deployment views
– and how models and conventions are used to describe these views.
An important goal of software engineering is reuse. We look at architectural
styles, which represent basic forms of architecture we can reuse in the design
of new systems. Frameworks and product lines provide complete architectures
designed for reuse.
Architecture is only one part of the design of a software system. The other
part of the design is the internal structure of the software elements
themselves. Software patterns represent reusable solutions to common design
problems at this level. We discuss a number of important patterns and give
examples of their use.
