A virtual data service provider is a way to change and speak for data from an external system in Dynamics CRM. A virtual data provider consists official source of a set of plugins which put into action backed CRUD operations. The data that is certainly represented with a virtual business is read-only. Logic through plugins may be implemented around the Retrieve, RetrieveMultiple and Erase messages delivered to the electronic data provider.
The standard OData Data Provider and the Ciel DB Info Provider are built using this approach. Developers can also build their own tailor made data providers. A custom data provider flexibly translates FetchXML query expression into the linked LINQ call to an exterior data source and returns the resulting records. This approach much more complicated to build up but can be more flexible. In case the schema of the external databases changes, only a tiny part of the electronic entity has to be remapped.
1 disadvantage of using virtual info providers is that some features that depend on the row-level Prevalent Data Program for Programs security principles are not provided by virtual agencies. These include lines, knowledge management, SLAs, replicate detection and mobile off-line capability. Furthermore, field metadata properties that validate on update would not apply to electronic agencies. For example , an area can’t contain a minimum benefit property on a virtual organization because the prices are being retrieved from an external resource and therefore may not be guaranteed to certainly not change upon update. Therefore, you should consider cautiously which organization processes to use virtual people for.
