is there any solution like clentdataset-DataSetProvider-query on delphi

Hi, Now  I use RealThinClientSDK which now is open source for 3-tier application.

Actually，the key point is how to store all changed records on client-side in one package just like clientdataset.delta, and then send these data to server-side, and then server-side how to handle these changed-records ?

I have skipped a lot of this thread but what I've read, particularly the quote above suggests to me that cached updates might be usable ?

How can I install it? I can't fine ...lpk. Just search path?

may be you get a different RTC version. the open source version on github don't support lazarus.
