I’m getting more and more fun working on "Delphi Labs" episodes! Today I have published the second part where I demo using Delphi XE for building a multitier database application system consisting of InterBase XE database, Delphi DataSnap server and client. This architecture is very close to the original Delphi MIDAS approach with dataset providers on the server and client datasets on the client communicating with providers via "remote server" connection components.
The demo is intentionally very simple and is supposed to serve as a "Hello World" quick reference for database development with Delphi and DataSnap XE.
In the video episode I’m using Delphi XE for building a DataSnap XE multitier database application for read and write access to "Employee" information in the InterBase XE sample database. The server and client applications are built from scratch in less than 10 minutes with Delphi components and just 2 lines of Delphi code.
In the video you can see that I have just installed a trial version of "Documentation Insight" from http://www.devjet.net/ and I’m really impressed with its functionality. It reads and writes xml doc inside the currently open editor window and integrates with Delphi help. Very useful!
