Datatypens is a term used to describe the categories that define the nature, constraints, and representation of values in computing. A datatypen determines the set of valid values, the operations that can be performed on them, and how they are stored in memory or on disk. Although the term is not standardized in all languages, it is widely used as a generic concept in programming, data modeling, and database design.
Datatypens are usually divided into primitive and composite types. Primitive types include integers, floating-point numbers, booleans,
Type systems govern how datatypens are used. They can be static or dynamic, supporting compile-time or run-time
In databases and data interchange formats, datatypens map to storage and schema definitions. SQL databases define
Datatypens continue to evolve with new requirements, such as large integers, high-precision decimals, temporal types, and
