Designing a
Method Network (Hierarchy)
You now have the ability to nest methods one
inside the other. Just as data can have sub-elements and at the same
time be a part of a larger data element, behaviors can be composed
of sub-behaviors, while at the same time being a sub-behavior in a
larger method. It is advisable to develop a series of steps to
accomplish this effort of mapping data to methods. The following
steps provide a good starting point for doing so.
1.
Create and refine the following essential analysis and design
documents:
·
A complete set of fully decomposed data flow diagrams.
This becomes the starting point for all the methods that will be
generated. The data flow diagrams assist in determining method
names, input and output values, and a preliminary plan for nested
methods.
·
A detailed object-relational element diagram (an
entity relationship diagram in the relational paradigm) used for
identifying the base classes in the application system.
·
A diagram showing the aggregate objects that will be
used to associate the higher-level processes with the appropriate
methods.
