Description
There are two projects there. The first one is DataSnap "Hello World" system implemented with C++Builder XE3 and it demonstrates a few essential DataSnap techniques:
- Building a DataSnap server application in C++ that listens on multiple TCP/IP ports
- Creating a DataSnap C++Builder XE3 FireMonkey HD application, manually generating
- C++ client proxy code and how to use in the client GUI
- Changing the functionality of the server and how to update client code
- Using "DataSnap Client Module" wizard
- Testing server functionality in Data Explorer
- Adding role based security to server methods
The second demo ("accelerator") demonstrates using DataSnap "SQL Accelerator" feature that makes it possible to use TSQLConnection component on a client application and access the corresponding TSQLConnection component on the server. That’s a very powerful technique and something that has been simplified in XE3 through enhanced "Modify Connection" Data Explorer tab for DataSnap connections.
