Where and what to read on the methodology of using IBDAC?

Question

Delphi

Good time of the day everyone!
At the moment I'm smoking a manual, but with 1100 pages inside, there are very few examples and recommendations.
A bare description of classes of methods and properties. You will still have to finish smoking, but I would like to figure out how best to use this wealth. Previously worked mainly with ADO and mssql. I would like to see the advantages and differences of these components in practice and in code.
Can source codes what where to look?
Thanks in advance.
