Tuple, Table, and Database Predicatestabase predicates to describe the data integrity constraints of a database design. The goal of this chapter is to establish these three different classes of predicates—which jointly we’ll refer to as .—and to give ample examples of predicates within each class.

Entscheidungsverfahren für komplexe ProblemeFrom this chapter onward we’ll assume that you’re thoroughly familiar with all terminology introduced in Part 1 of this book. Only if we deem it necessary will we make explicit references back to where specific terminology was first introduced and defined.

Entscheidungsverhalten als rekursiver Proze?In this chapter, we’ll give a demonstration of how you can formally specify a database design. Formalizing a database design specification has the advantage of avoiding any ambiguity in the documentation of not only the database structure but, even more importantly, of all involved data integrity constraints.

To do so, we won’t require the formal introduction of any new concepts; we’ve already presented all ingredients for specifying queries.

Of course, you want to do more than just specify a database design; you usually would like to . it using some DBMS. In this chapter we turn our attention towards implementing a database design.
