About Talend Data Mapper
Talend Data Mapper lets you define and execute transformations (called maps) between data records or documents.
Integrated within Talend Studio, you create a mapping by dragging and dropping the data from an input document to an output document in Talend Data Mapper. For more complex mappings, Talend Data Mapper lets you create an expression that specifies the value of an element and is built from functions operating on input (or output) values.

Three main parts of Talend Data Mapper
-
Repository navigator - The Repository navigator is a tree view in the left pane consisting of structures, maps, and namespace containers. To view one of these workspace objects, select it in the browser and open it.
In the Talend Studio, the Repository navigator is located under the Hierarchical Mapper node, which can be found in the Data Mapper tab in the Mapping perspective; and in the Repository tab in the Integration and Mediation perspectives, under the Metadata node. When Talend Data Mapper is running in Eclipse without the Talend Studio, it is located in the Project Explorer.
-
Functions - The Functions tab in the left pane has all of the functions that can be used to create expressions.
-
Editor Area - The editor area contains an editor for each structure, map, or namespace container that is open. You can close an editor by clicking the X icon on the editor's tab.
More about Talend Data Mapper
At any time, you can view all or a portion of your mapping using a sample document. You can also view all or a portion of the sample document. In addition, a powerful search capability is included that allows you to look for any text in your transformation maps, expressions, or document definitions.
You can import document definitions, also called structures, from specification files (like XML Schema, Guideline XML, or examples), or you can enter them manually. Structures can refer to other structures, allowing any part of a document definition to be reused. Furthermore, to handle cases where a structure is derived from another structure (like a specific implementation guideline of an EDI or XML specification), a structure can inherit from another structure.
Structures can have example document instances associated with them, which you can edit directly. Example document instances are also used when testing maps associated with the structure.
You can use various runtime projects (provided separately) in the environment where you can execute maps independently of the Studio.
