Data Types

Official Content

The GeneXus Data Types can be divided into:

Basics: the very well-known data types (Numeric, Character, etc.).
Business Components: to use the Business Logic of Transactions in other objects, use Business Components.
Extended Types: those used to handle things like Files, XMLs, Directories, Web sessions, Mail sessions, Excel and Word documents, etc.
Structured Data Types: it is the GeneXus object which allows defining complex data structures.

Where are Data Types used?

In an Attribute definition: only Basics are allowed
In a Domain definition: all except Business Components are allowed
In a Variable definition: all kinds of data types are allowed
In the members of a Structured Data Type definition: all kinds of data types are allowed
