CMM Subjects are built to provide logical building blocks for creating CMM Messages. CMM Subjects are reusable assets that can be used in different CMM Messages (e.g. Address Subject, Customer Subject). These subjects are collections of CDEs that represent a business entity. The rationale behind CMM Subjects is to promote reusability within the system and simplify maintenance for the creation of CMM Messages. Building CMM Subjects involves the selection of the CDEs to be encapsulated in each logical entity into the metadata repository. The key aspects involved in creating CMM Subjects are as follows:
CMM Subjects should be refined and reviewed by the Information Development team before being made accessible for message creation.
Listed below are example CMM Subjects:
Example 1 - Creation of CMM Subjects and Messages – Work Instruction Overview
This solution will outline the process for the administration and creation of CMM subjects and CMM Messages. The solution will provide an easy to use user interface for creation and maintenance of CMM Components and CMM Messages.
The proposed CMM Message creation process is as follows:
Step 1 – Create CMM Subjects
- Design and build reusable CMM Subjects that can be used in different CMM Messages, for instance: Address Subject, Customer Subject and so on. These subjects are collections of CDEs to represent a business entity. Reason behind this is to promote reusability within our system and to provide easy maintenance for CMM Messages.
Step 2 – Create CMM Message
- Understand business requirement
Review business request and determine data requirement as this drives the creation of the CMM Message.
- Access existing components and build new Subjects
Based on the data requirements existing Subjects can be used to define the message data. If need be, a new Subject can be created as outlined in Step 1.
- Build CMM Message
Once the Subjects have been identified, a CMM Message is created which encapsulates the required Subjects and additional CDEs that may not be part of a Subject.
Step 3 - Exporting CMM Message to Runtime Environment
- Publish CMM Message
Involves transferring the created CMM Messages from XML Canon Repository to the Tibco Repository for run-time.
Note: The CMMs are independent of the application that uses them. In our example, we are using Tibco IM to send the messages.
Example 2 - for sample CMM Subjects created in Metadata Repository
CMM Subjects are logical encapsulation of Common Data Elements (CDE). They are created for usability and manageability
Customer Reference Subject
Description: References an Individual OR Organization that is represented either by an Enterprise ID or Individual ID or
Organization ID attributes. Enterprise ID, Individual ID and Organisation ID are all optional values.
Account Reference Subject
Description: Account Reference pertains to a unique identifier of an account in TDWI.
