The new Borland C++ 5.0 comes with Visual Database Tools, 
but I don't know if this will allow you to create full 
database applications like you can using Visual dBase or 
Delphi. This new version should be out anytime now. The 
upgrade price is $199.95

Hope this helps

The dBase data format is well published and it is relatively easy to 
write a routine that reads it. I can upload a Pascal routine for your 
perusal if you need it.
The Paradox Engine is available from Borland with functions to include in 
C and Pascal programs to read Paradox (DOS) tables. Unfortunately it is 
not public domain.

According to various [Borland] Sources, I have learned:

- the Borland Database Engine, roughly analogous to Microsoft's
  JET Database Engine, is included in the package, with all its
  header files.  The "old" BDE had a C-language style API, that
  looked a lot like ODBC.  The 5.0 BDE interface (apparently)
  includes classes for things like tables, data sets, etc., which
  I speculate are roughly analogous to the CRecordSet type classes
  in the MFCs.  The BDE is capable of reading & writing all the
  usual suspects: Paradox, DBase, FoxPro, and Access files, as well
  as using ODBC to read/write just about anything else.

- a "Visual Database Designer" is included, which (I speculate)
  seems to include a Delphi-like drag-and-drop forms designer, and
  some kind of .ocx (custom control) support that is database-aware.
  C++ classes encapsulating the included controls are also included.
  I know very little about this part; it sounds rather like the
  DAOs with some better support for data-aware controls.

Cheers,

Larry
