Methodologies, techniques and tools covers the multitude of accessories needed in any system developers toolbox. Whether studying or implementing an entire business system or just redesigning this is an essential read. It's strong point is the approach to methodologies. By taking a close analytical view of each (such as SSADM, UML, ETHICS, SSM, RAD, JSD and more)it is possible to identify the correct one for a given situation.Techniques gives much of the same view of things - a level unbiased opinion of documentation through entity modelling, normalisation, DFD's, Entity life cycle etc.And lastly, the tools section covers project and database management, system repositories, drawing tools and CASE tools. All-in-all well worth the cover price, and a useful addition to any IT bookcase. Ideal for consulting at a later date as a reference manual, though it has to be said that it is weak in the particular area of System Development Lifecycle(SDLC)and should be used in conjuction with perhaps Ian Sommervilles or Shari Lawrence Pfleeger's "Software Engineering" books.
