Legacy information systems are an ever-present factor in
modern-day business. This paper produces a summary of some
of the approaches available that would be most beneficial to
Rolls-Royce. It is noted that the approaches are not necessarily
mutually exclusive, and elements can sometimes be combined to
produce the best approach in a given situation.
It is concluded that only a few of the approaches outlined have
elements that are valid and should be considered in the case of
PIMS and related databases in Rolls-Royce. As a result of the
conclusions reached during the analysis of options, Rolls-Royce
is considering combining elements from several of the various
approaches. This solution is designed to satisfy as many
requirements of the user population as possible, whilst
streamlining the costs required to maintain the database.
Rolls-Royce now intends to cost out the implementation of the
