ODBC Server Reference Manual

Architecture Overview
HP NonStop ODBC Server Reference Manual—429151-002
2-2
Following subsections cover background information, the client-side view, and the
server-side view. The client-side view describes what the application deals with
(connecting, sessions, databases, SQL dialect, configuration of options) and the
server-side view describes the HP server aspects (process structure, message flow,
translation schemes, configuration, and management).
The NonStop ODBC Server has many types of users; it is useful to identify them, as
each type sees the architecture differently.

;
Client user The person who writes or uses the client DBLIB or ODBC
application. This user is aware of connecting to the database
and using the SQL database objects.
Client administrator The person who configures and manages the client
applications. This user is aware of network communication
and configuring the HP NonStop ODBC/MP driver, but does
not necessarily know much about the HP side.
HP system
administrator
The person who configures and manages the NonStop
ODBC Server components on the HP side. For this
discussion, this category also includes administrative jobs for
