Attribute Varying Length

For text attributes, the varying length option allows you to specify that the length of the text attribute can vary when stored in the database. The database only stores the actual length of the text string.

For example, assume that varying length is specified for the Name attribute of the CUSTOMER entity type and the length of the attribute is 30 characters. In the implemented system, if the value of CUSTOMER Name is only 20 characters, the database only stores 20 characters.
