ForSyDe is a transformational system design methodology, where an initial abstract system model is refined by the application of semantic-preserving and non-semantic preserving design transformations into a detailed model that can be mapped to an implementation.
In particular, we show that the spaces P2=span{1,t,cost,sint,cos2t,sin2t}, Q=span{1,t,t2,cost,sint} and I=span{1,t,cost,sint,tcost,tsint} are also suitable for shape preserving design, and we find their normalized B-basis.
The principle of structure preserving design means that, in an ideal world, these models should be reused during the implementation of the eventual system.
Most importantly, the experience accumulated during this study has highlighted the importance of structure preserving design in the construction of systems that make use of computer interpretable guidelines.
If we aim at a structure preserving design then notational convenience, i.e. the ease with which a knowledge representation language can be read, written, and understood, acquires a greater importance than the word "convenience" might suggest.
The experience accumulated during this study highlighted the importance of structure preserving design, that is to say that the models used in the design and implementation of a knowledge-based system should be structurally similar to those created during knowledge acquisition and analysis.
