Datasnap originated in Midas (more than 10 blog posts)

As Midas starting from Delphi3,delphi4 is MIDASIII in Midas Ii,delphi5, and then using tcp/ip,http based on COM remote data modules, (D) COM builds strong communication capabilities.
Changed from Delphi6 to Datasnap, until D2007 this framework has been in use.
D2009 has re-architected datasnap-to remove COM dependencies, using TCP/IP to generate remote service objects and client connectivity in a more lightweight manner. It also provides the ability to communicate with the. NET program developed by Delphi Prism2009.
DELPHI2010 is built on the D2009 architecture and further expands on this architecture, including the use of two wizards to create new deployment targets (VCL form, window service, console and web-oriented isapi,cgi or Web App Debugger). HTTP (S) transport protocol, HTTP authentication, client callback functions, rest and JSON support, and use of filters to support compression and decompression.
