Canonical data model - Ashutosh

  1. 1. Canonical Data Model Turing Works and Mule
  2. 2. Canonical Data Model Often, people from various bu siness units have different terms or abbreviations for the same concept, which may lead to an error while interpretation. For example, the purchase or der number can be denoted in several ways with dif ferent parameters and is also based on departments in the organization. Probably, they would be usin g codes like PO No, PO ID, PO Code, etc. This lea ds to multiple custom versions of enterprise-wide data models such as Product, Customer, Supplier etc. All models have redundant custom versions of
  3. 3. Sometimes, these service contracts may express sim ilar capabilities in different ways, leading to in consistency and might result in misinterpretation. An ideal solution for this problem is to have ser vice contracts that are standardized with naming c onventions. Naming conventions are applied to serv ice contracts as part of formal analysis and desig n processes. The use of global naming conventions introduces enterprise-wide standards that need to be consistently used and enforced. The Canonical E xpression pattern, using Canonical Data Model (CDM ) solves all the related problems.
  4. 4. Canonical Data Modeldefines common architecture f or messages exchanged between applications or comp onents. The CDM defines business entities, attribu tes, associations and semantics relevant to specif ic domain. Canonical Data Model is application i ndependent. Examples of some CDMs are: OAGIS, ACC ORD, HL7, HR-XML. The CDM shift simplifies the des ign as shown in the diagram below.
  5. 5. Benefits of the CDM shift are: Improve Business Co mmunication through standardization Increase re-us e of Software Components No. of possible connectio ns is (n * 2) against n (n-1).
  6. 6. Reduce transformations Reduce Integration Time and Cost Few downsides while using CDM are CDMs are too generic (BIG in size) (Light versions might re lease in order to solve this problem)
