Illogically or inconsistently stored data can cause a number of problems.
-
A poorly designed database may provide erroneous information, may be difficult to use, or may even fail to work properly.
-
Anomalies are any occurrence that weakens the integrity of your data due to irregular or inconsistent storage (delete, insert and update irregularity, that generates the inconsistent data).
-
The process of designing a relational database includes making sure that a table contains only data directly related to the primary key, that each data field contains only one item of data, and that redundant (duplicated and unnecessary) data is eliminated.
-
The task of a database designer is to structure the data in a way that eliminates unnecessary duplication(s) and provides a rapid search path to all necessary information.
