Vom ERM zur relationalen Datenbank,Presumably readers of this chapter will have had some basic acquaintance with linear algebra in elementary courses. We go beyond such courses by pointing out that a lot of results hold for free modules over a commutative ring. This is useful when one wants to deal with families of linear maps, and reduction modulo an ideal.

Transcendental ExtensionsBoth for their own sake and for applications to the case of finite extensions of the rational numbers, one is led to deal with ground fields which are function fields, i.e. finitely generated over some field ., possibly by elements which are not algebraic. This chapter gives some basic properties of such fields.
