Unit-Zusammenfassung

This Unit showed how and why relations should be normalised. It prevents problems and saves money. A careful planning in the conceptual phase helps implementing and normalising a table properly. Although there is a fourth and a fifth normal form (that were not discussed here), usually it is enough to normalise up to the third normal form.
