OS/2 Database Manager Application Agent

      A method is described which provides for a mechanism which will
field and dispatch OS/2* Database Manager Structured Query Language
(SQL) requests from a database client on an OS/2 Database Manager
server.

      The distributed OS/2 Database Manager is intended to be a
seamless system which is transparent to the user.  The location of
where the SQL requests are issued should have no effect on the
how a programmer manipulates the data in the database.  To the user
the data is handled the same regardless of whether the SQL
requests are issued from a client workstation or on the database
server itself.

      There must be a mechanism in place which allows the OS/2
Database Manager to field and route SQL requests to the database
engine at a remote database server.

      The  OS/2  Database Manager will provide a Transaction
Program (TP) program known as the Application Agent.  This TP is
invoked on the Database Server by the OS/2 Communications Manager.
The Application Agent serves as the requester's representative on
the server node.  Its purpose is to receive requests from the remote
application, to map the request to the appropriate Database Manager
internal format, and to call the database engine to perform the
requested function.  The Application Agent maps the reply to the
appropriate Advanced SQL Protocol (ASP) data formats and sends it
back to the requester.
