A derived data type is a complex classification that identifies one or various data types and is made up of simpler data types called primitive data types. Derived data types have advanced properties and uses far beyond those of the basic primitive data types that operate as their essential building blocks.
Derived data types can be made up of simple integers or characters, as well as other simple data types like Boolean true or false conditions, basic character strings, or anything else that is primitive based on its inability to be broken down into simpler components. Primitive, or basic, data types are those that have innate support on a programming platform.
Programmers can build all sorts of unique data types or classes using eXtensible Markup Language (XML). With XML, developers essentially code an advanced, user-defined data type by putting its unique attributes and elements into an XML code module. In pioneering the use of XML, some developers illustrated its uses by creating a range of virtual objects. For example, a virtual chair in XML may be composed of a range of data attributes detailing this virtual object’s physical dimensions, color, material makeup, or other invented properties.
