One solution that you might want to consider is SAMeDL (SQL Ada
Module Description Language).
SAMeDL is a database programming language, currently undergoing ISO
standardization, that supports the development of Ada application interfaces
to SQL-based RDBMSs. It differs from other Ada/SQL binding techniques such
as ANSI Ada/SQL Module Language or Ada/ESQL by providing features that
better fit Ada software engineering principles.
It supports:
o A standard modular interface
o isolation of DBMS differences and COTS DBMS dependencies (handled
by the SAMeDL compiler and is thus transparent to the user), and
therefore will allow your applications to be as vendor independent
as possible
o tighter integration with Ada applications by promoting facilities for
the use of strong and abstract typing, record oriented interfaces, and
exception handling.
Intermetrics has implemented SAMeDL compilers that support a variety of
databases from vendors such as Sybase, Informix, Oracle, Progress, and CA/XDB.
