    Hi all,

    apologies if the answer to this is somewhere obvious, sometimes I don't fully understand database terminology!

    Does ORM support data changes and propogate them to the client when the underlying data source value changes?  For example, we currently use ODP.NET database change notifications for this functionality.

    Hello Damon Luck,

     We do not support the ODP.NET change notification feature as of now. OpenAccess has a well defined concurrency control mechanism to detect and handle concurrenct changes on the database. You can find details of it, here.
    Note that OpenAccess maintains certain caches to improve application performance. You can find more information about it in these blogs - 1st level cache , 2nd Level Cache
    Objects maintained in this cache would need to be manually evicted (using API) in case the data might have been modified by externally.

    Do get back to us in case you need further clarifications.

    All the best,
    the Telerik team
