DATA TYPES

The term “data type” in software programming describes the kind of value a variable possesses and the kinds of mathematical, relational, or logical operations that can be performed on it without leading to an error. Numerous programming languages, for instance, utilize the data types string, integer, and floating point to represent text, whole numbers, and values with decimal points, respectively. An interpreter or compiler can determine how a programmer plans to use a given set of data by looking up its data type.

Primitives are predefined data types that are independent of all other kinds and include basic values of particular attributes, like text or numeric values. They are the most fundamental type and are used as the foundation for more complex data types. Most computer languages probably employ some variation of these simple data types.

Composite data types are made up of various primitive kinds that are typically supplied by the user. They are also referred to as user-defined or non-primitive data types. Composite types fall into four main categories: semi-structured (stores data as a set of relationships); multimedia (stores data as images, music, or videos); homogeneous (needs all values to be of the same data type); and tabular (stores data in tabular form).

A user-defined data type (UDT) is a data type that derived from an existing data type. You can use other built-in types already available and create your own customized data types.
