The steps in developing
any application can be represented as a linear sequence where each step in the
sequence is a function, which passes its output to its successor function.
Adherence of a ‘waterfall development model’ ensures quality software, which is
‘complete’, ‘efficient’, ‘usable’, ‘consistent’, ‘correct’ and ‘flexible’.
These traits are also some of the core underpinnings of a well-built database.
The waterfall model can be applied to database design theory as effectively as
it is applied to other software engineering theory. The steps can
be summarised as follows:
