The intended user of f90SQL is an experienced Fortran programmer or developer interested in obtaining database access from their Fortran code. f90SQL can also be a useful tool for programmers porting legacy code to Windows based platforms. The use of the f90SQL spans three areas: SQL statements, ODBC function calls, and Fortran 90 programming. This manual assumes that you have a good working knowledge on the Fortran 90 programming language and at least some general knowledge of DBMS. Familiarity with SQL is also useful, but Chapter 3 will give you the basics in this area . There are many good books in the market that address each of these topics individually (check below for some book recommendations).
