ADO Database Delphi

Question:
What is the definition of 'IDAPI'? What is 'SQL Links'?
Answer:
IDAPI is the Integrated Database Application Program Interface.
BDE is a way to access multiple data sources with a consistent
API. The distinction is in the terminology: IDAPI is the API
for the BDE. It includes all the functions necessary to access,
manipulate, etc. the data; BCB, dBASE for Windows, Quattro Pro,
and Paradox for Windows use these functions to access data:
You can use them yourself in your programs. If you look at the
BCB source you will see these functions used. They are prefaced
with "Dbi" (e.g. DbiCreateTable).
SQL Links is a collection of native drivers that enable you to
connect to remote database servers.
