Abstract

The goal of the first chapter is to quickly get you started writing LogiQL programs. Such a program tries to model aspects of a realworld domain inside a computer. The program is written in the LogiQL programming language, a member of the Datalog family of languages, and relevant data are stored in a LogiQL database. By the end of this chapter, you will have built a working LogiQL program. Your program will include constraints, derivation rules, and fact assertions, and this chapter introduces you to all of these aspects. The program is used to record and derive information of interest about the British monarchy. In writing this program, you should obtain a feel for the structure of LogiQL programs, the basic syntax of the language, and how your program is processed. Later chapters will go into further detail on these topics and introduce you to many other interesting and powerful features of LogiQL
