I would like some experts to comment on and give me some reference links on the following questions.

I know what In memory computing can do to transaction processing and querying in databases and I am looking forward to testing some applications on SQL Server 2014 - that has in memory computing ability.

Q 1   - Generally speaking - if a application that normally runs on SQL 2012 - would it need significant changes to run on SQL 2014 ( or any at all ).
Q2 - reated to Q1,  I mean I am expecting regardless of in memory or not ,  applications could query/update SQL server 2014 data as it used to do on SQL 2012 ?
Q3 - I read somewhere that you can ( the DBA ) nominate some tables to run in memory - does this mean to get the benefit of in memory computing of SQL 2014 - does the DBA have to do the "tweaks" ?

Thanks and reference URLs would b great.

Q1 - If an application runs in SQL 2012, it should run in SQL 2014 with few if any changes. However, that is not necessarily true of "in memory", whcih is not switched on by default.
Q2 - See Q1.

Please note that in memory computing has some limitations - see this article and scroll down to "Limitations".

Note particularly that certain types of data types are not supported, and that FOREIGN KEY, CHECK, UNIQUE and IDENTITY are not supported, among others.

Q3 - Yes. It's more than "tweaks" - see thithis article for more details.

Hi Phillip,

Thanks for the information it really helps.
Meanwhile I have been reading some articles as well.

With the "Limitations" does that apply ONLY to the In Memory enables editions ? what is your understanding ?  ( I believe SQL standard does not contain In Memory capability ).

No, the "Limitations" apply to tables which are In Memory enabled. It is not enabled by default.

Out of the box, those Limitations do not exist with tables which are not In Memory. They didn't make SQL Server 2014 to make it non-compatible with SQL Server 2012. It's just that there is extra functionality IF YOU WANT IT. If you don't, those limitations do not exist.
