c & c++

1. Developing an ODBC Driver some thing similar to the existing
ODBC drivers for oracle, access etc.

2. In our case the database is nothing but a binary file & not
a specific database.

3. We need to provide an interface between a window application
say excel and our ODBC driver.

4. The ODBC driver must be capable of getting the data from the
browser using XML tecniques.

In short we need to develop a ODBC driver for a specific file
structure which has two way interface i.e, one with the file structure itself & the second with excel or access or any other application.

Can any body help me??? Any sugestions are welcome....

thank you
