My name is Christoph Draxler, and I am currently working in the field of logic and databases here at the computer science department at the univer- sity of Zurich. In my doctoral thesis I propose a new approach to coupling Prolog-like logic languages with relational (or other) database systems. This approach uses database set predicates, which are an extension of the traditional set predicates as they are known in Prolog et al. For the implementation I plan to use Quintus Prolog and Oracle because we have both systems installed. I know that there exists a database interface for Quintus Prolog to Oracle, but I don't want to use it because it is too restricted for my purposes... Both Oracle and Quintus Prolog offer a tcp/ip interface. In fact, the oracle tools such as ProSQL etc. use the tcp/ip connection to the main Oracle system. In the tcp/ip manual for Oracle it is said that tcp/ip may be used by application programs wishing to access the database - but it does not say HOW to do this, WHAT format any access request must have, etc. So, here's the question: Is there anybody out there who has set up a system consisting of an application program that accesses the Oracle database system via tcp/ip? What is the general architecture of that system? What is the format of database access in Oracle? What were your experiences? What documentation did you use? Did Oracle Corp. help you in any way? ANY information on the above subject is welcome.

The Oracle libraries handle the network connection, so all you do is link your application to them, and pass them the two_task data at runtime. Oracle creates a shadow process on the server that listens to your application and passes data to/from the database. - Woody -- I want a GOOD reason with some moral backbone why Americans are dying in the Mid East.
