ADO Database Delphi

Question:
Can I use the MSACCESS driver to create multi-threaded
applications?
Answer:
Yes and No. DAO 3.0 is not thread safe so all applications using
DAO (including Borland's MSACCESS driver) must access the
database through the main process' thread. The application can
still use threads as long as the threads do not do any database
operations with the MSACCESS driver.
