    The meaning of "persisted"?

    I have a question.

    You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create a multi-tier application. You use Microsoft ADO.NET Entity Data Model(EDM) to model entities. The model contains entities named SalesOrderHeader and SalesOrderDetail. For performance considerations in querying
    SalesOrderHeader, you detach SalesOrderDetail entities from ObjectContext. You need to ensure that changes made to existing SalesOrderDetail
    entities updated in other areas of your application are persisted to the database
    What does it mean "persisted" here? I think that it means "Same".

    This is badly written, and is a misuse of the intransitive verb "persist."

    Re: The meaning of "persisted"?

    For some reason, computer science uses 'persist' as a synonym for 'store' or 'save'. I've seen it used this way before, although I agree, it does seem wrong. I'd classify it more as jargon, as it seems to exist in this context only in the world of computers.

    Not sure why they can't just use the words 'saved' or 'stored' instead of persisted.

    Re: The meaning of "persisted"?

    Note that your question should have been "What does 'persisted' mean here?" (not "What does it​ mean 'persisted' here?")
    Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.

    I agree it sounds odd. However, it seems to mean that the data remain intact, in the RAM, without *necessarily* being stored on a medium such as a hard drive or flash memory.
