Message definition (Kexi/Handbook/Introduction to Databases/Database Design)

Database design needs careful planning. Note that '''''Persons''''' table redesign proposed in section [[Special:MyLanguage/Kexi/Handbook/Introduction_to_Databases/Database_and_Spreadsheet#Data_integrity_and_validity|Data integrity and validity]] can generate problems when the table is filled with data. For example, renaming a field is a simple task, but splitting the '''''Address''''' field into separate fields requires careful and tedious work.

Design af databaser kræver omhyggelig planlægning. Bemærk, at den ændring af deignet af tabellen Personer, som blev foreslået i afsnittet Dataintegritet og gyldighed kan give problemer, hvis tabellen er fyldt med data. For eksempel er det en simpel opgave at omdøbe et felt, men at opdele feltet Adresse i adskilte felter kræver omhyggeligt og trælsomt arbejde.
