Sometimes, a database design that looks OK at first sight may have some hidden problems. One such kind of problem is Non-Atomic values. This means that the value stored in a single column in the database is actually a combination of multiple values which makes the database harder to work...
Provided are techniques for identifying normalization violations. Selection of one of a data model, a portion of the data model, and an object in the data model is received. Selection of one or more normalization rules is received. One or more normalization violations are identified in the one...

Normalization usually involves dividing a database into two or more tables and defining relationships between the tables. The objective is to isolate data so that additions, deletions, and modifications of a ...
