Design Patterns for Real-Time SystemsExperienced developers find when they approach a new problem to solve, that the situation usually has something in common with a solution they have already either created or seen. The problems are not identical and the identical solution will rarely solve the new problems, but the problems are still similar, so a similar solution will probably work. The "similar solution" generalized and formalized, is called a design pattern. Creating design patterns is a problem of abstracting the similarities of the two problems and the solution so that the generic aspects of the original solution can be applied to the new problem at hand. Design patterns codify design expertise and have been used in an intuitive way as long as design has been a recognized activity. The intentional use of design patterns allows us to think about our designs using a vastly richer vocabulary and to this think critically about the tradeoffs we make during the design process – resulting in better optimized, more robust systems.
