SPARCL Tutorial
This is a tutorial introduction to SPARCL, the language which is built using the principles of the hypothesis: it is semantically a logic programming language which is built around partitioned sets; it is representationally a two- and three-dimensional visual programming language; and it is implemented as an integrated development environment (IDE). The relationship of the various elements of SPARCL to the design principles is discussed in the next chapter. The tutorial material in this chapter is extracted from the interactive tutorial that is part of the SPARCL IDE, and which was the basis of the usability testing discussed in a later chapter.
The SPARCL tutorial is presented in three sections:
2. SPARCL representation and meaning.
3. Presentation of an application of SPARCL
4. Create 'Column Sum Query'/1 predicate.
