Those notes are in keeping with a one-quarter direction given on the division of Biophysics and Theoretical Biology of the college of Chicago in 1916. The path used to be directed to graduate scholars within the department of organic Sciences with pursuits in inhabitants biology and neurobiology. just a mild acquaintance with likelihood and differential equations is needed of the reader.

Sample text

They are a precise, compact means of representing factual information and as a means of communication they are ideal. A picture represents a 'common language' between user, analyst and designer which can be understood and is far more efficient than text. Furthermore, as the analysis progresses, constant feedback is possible, using the picture as a basis. Diagrams are also easily maintained, meaning they are more likely to be up to date. Any changes, whether they be made during analysis or after the project has gone live, can be easily incorporated because it can be seen where the changes need to take place.

A n activity is any grouping of actions, whether it be a broad, general grouping (for example, household management), to something more specific (cooking), even more specific (make cakes) or very detailed (put egg into basin). Any organisation, business or 'area' can be classified by a broad activity name which describes its purpose. For example: • Banking (for a bank) • Helping the aged (charitable organisations) • Government (the government of the country). 20: Data flow diagram showing entity types or groups 37 This broad grouping, which describes what the business is set up to do (its purpose), can be decomposed into a network of successively more detailed classifications of the organisation's activities.

The point is that it does not really matter which is used—the content of the diagrams is the main concern. As illustrated, all the diagrams can be used to express the same content—the choice is simply one of aesthetics, simplicity of drawing and ease of presentation. I like lists because they are easy to compile, neat to look at and easy to understand. 1 Networks of activities One fundamentally important point has not been mentioned yet. Until now the implication may have been that activity decomposition produces a true 'hierarchy' or tree structure.
