In this video we begin our journey to produce data-aware applications.  Before we can do this we need to understand how datasets work.  Probably the most common dataset is TClientDataSet which is used extensively in all sorts of data-aware applications, making knowledge of it essential in building modern Delphi applications.  In Part 1 we take a close look at many of its properties and methods and using its abilities to load and save data to either a xml file or binary packet.  Examples are done using the VCL and you should be able to follow along even with very old versions of Delphi.

I am still watching the first video. Really helpful. There were things I did know, and things I did not know. After I've watched all of it, I am planning to buy the next video.
