Hi,

Data type defines the structure of your xml message.Message type is the wrapper of data type.You will be using your message type while mapping and not the data type.Its the abstraction concept used in oops

A data type in a programming language is a set of data with values having predefined characteristics. Examples of data types are: integer, floating point unit number, character, string, and pointer.

The characteristic of columns and variables that defines what types of data values they can store. Examples include character, floating point and integer

Check out the details:

A message type comprises a data type that describes the structure of a message. At the following points in SAP Exchange Infrastructure you can refer to the message to be exchanged at runtime by using the message type:

2) Regarding the difference between XI 3.0 and PI 7.0, this threads will clear your doubts:

data types just define the abstract XSD structure . but since In XI we are using XML langauge. so We need a Root element in our message. that root element is added by Messagr type.

means data type is just an abstarct structure and message type add root element to data type.

and one message type corresponds to one data type only............
