Specifying Systems: The TLA+ Language and Tools for Hardware and Software Engineering
This ebook is the distillation of over 25 years of labor through one of many world's most famed machine scientists. A specification is a written description of what a approach is meant to do, plus a fashion of checking to ensure that it really works. Specifying a approach is helping us know it. it is a sturdy concept to appreciate a process ahead of development it, so it is a sturdy notion to jot down a specification of a process ahead of imposing it.

Design Abstractions and Occurrences If we examine computer system specifications for record layouts, or look at listings and forms, we are looking at the "Design Abstractions". A Design Abstraction is simply the means by which the information needed manifests itself in the system design. Look for record layouts forms (input, output or master file) listing layouts screen layouts The abstractions are simply the "templates": the record layouts and forms themselves. If time is limited, for Data Analysis purposes concentrate on master record layouts and forms.

We try to provide as varied a diet as possible by using details about each food type, such as calorific value, contents, vitamin content, carbohydrate content etc. Notice that we don't have individual diets for each animal. Notice also that we don't reserve animal areas for one animal type. This means that in practice we mix animals in an animal area (although obviously we use our common sense here). Finally, it helps us to know which types of animal the keepers are capable of looking after. Each keeper may be looking after only a subset of this range of types at any one time.
