Common data model
A common data model (CDM) can refer to any standardised data model which allows for data and information exchange between different applications and data sources. Common data models aim to standardise logical infrastructure so that related applications can "operate on and share the same data",[1] and can be seen as a way to "organize data from many sources that are in different formats into a standard structure".[2]
A common data model has been described as one of the components of a "strong information system".[3]
Examples of common data models
Microsoft Common Data Model
The Microsoft Common Data Model is a collection of many standardised extensible data schemas with entities, attributes, semantic metadata, and relationships, which represent commonly used concepts and activities in various businesses areas such as "automotive, banking, commerce, educational, healthcare, marketing, sales, legal and non-profit institutions".[4] It is maintained by Microsoft and its partners, and is published on GitHub.[5] Microsoft's Common Data Model is used amongst others in Microsoft Dataverse[6] and with various Microsoft Power Platform[7] and Microsoft Dynamics 365[8] services.
Other examples
RailSystemModel is a common data model for the railway sector.[9]
The Climate Data Store Common Data Model is a common data model set up by the Copernicus Climate Change Service for harmonising essential climate variables from different sources and data providers.
Once-only principle#X-trans.eu was a cross-border pilot project between the Free State of Bavaria (Germany) and Upper Austria with the aim of developing a faster procedure for the application and approval of cross-border large-capacity transports. The portal was based on a common data model that contained all the information required for approval.
SX000i is a specification developed jointly by the Aerospace and Defence Industries Association of Europe (ASD) and the American Aerospace Industries Association (AIA) to provide information, guidance and instructions to ensure compatibility and the commonality. The associated SX002D specification contains a common data model.
There are many more examples of various common data models for different uses published by different sources.[10][11][12][13][14]
