  Data mapping in services and connectors — Concepts and terms

 

Pega 7 Platform uses the term data mapping for the task of converting data received from, or sent to, an outside source or system into the formats, values, and objects needed within an application.

Most system interfaces, known as connectors and services, require data mapping in both directions, for the request and the response.

Typically the source (of outgoing data) and the destination (of incoming data) is a property on a clipboard page. For a developer, establishing the relationships among the external formats and structures and internal formats and structures can be laborious, exacting, and tedious. When dealing with legacy external systems, differences in character sets, the endian orientation of binary values, the representation of numbers and dates or times, and so on add to the complexity of data mapping.

Note: For more information about data mapping of SOAP messages, see Data Mapping XML, a document available from in the Integration area of the PDN.

Pega 7 Platform offers several features that can simplify and speed this development task, including:
