Data Types

Previous Next

USoft Definer has knowledge of the principal data types used by databases and database drivers.

A data type specifies what kind of data a column must be equipped to store:

Text (of various types);

Numbers, for example, integers, or amounts of money;

Calendar dates, or times of day, or a combination of these;

Relatively large and unstructured data such as images, videos or documents.

In a USoft application, you express that data in a given column is of a specific data type. You do this by having a Domain use the Data Type, and then making sure the Column is based on that Domain.
