Controller layer
The Controller layer is the conductor of operations for a request. It controls the transaction scope and manages the session related information for the request. The controller first dispatches to a command and then calls the appropriate view processing logic to render the response.
Integrating with back-end systems and external applications
External systems integration is a key feature of the WebSphere Commerce solution. In WebSphere Commerce business logic is enabled for integration and built-in adapters and interfaces are provided for common integration points. Additionally, the WebSphere Commerce integration solution leverages integration standards by using various IBM connectivity solutions.
Back-end integration legacy messages
The WebSphere Commerce offers support for messages which use the legacy message format. Unless you are migrating from a previous version of WebSphere Commerce Suite, it is recommended that you use the XML messages instead, since they accomplish the same function, and are easier to read and maintain.
NCCommon.mod - source file
WebSphere Commerce defines all inbound XML messages based on DTD files. Each DTD file consists of several XML elements and the NCCommon.mod file.
