Prognosis and the Course of Schizophrenia

We are programmers, in the sense that it is our concern to improve the process of program construction. Therefore we want to answer questions like: What is programming, why is it so difficult and error-prone, and how can we learn what is needed to make the process more manageable? In the following we shall address these issues in a relational framework. Section 10.1 gives an introductory overview explaining the background to our approach. Section 10.2 shows how we deal with (recursive and non-recursive) datatypes in the relational framework. Section 10.3 discusses programs in this context, concentrating on a class of programs characterized by relational equations of a specific but quite general shape. Program termination is the subject of Section 10.4. Finally, Section 10.5 briefly touches on the design and execution of (terminating) programs. For a more extensive treatment see [Doornbos 1996].
