SQL Gateways
The NonStop ODBC Server is a HP product that provides connectivity between certain
SQL client applications (actually between certain SQL APIs) and NonStop SQL/MP.
The NonStop ODBC Server supports both DBLIB and ODBC clients. There are other
products on the HP server to support DAL (Data Access Language) and Oracle clients.
The goal of all these products is to promote applications that can use NonStop
SQL/MP on the NonStop server. The current suite of products covers the most popular
client SQL APIs.
SQL Gateways
The NonStop ODBC Server can be thought of as an “SQL gateway” in that it connects
the client’s SQL environment (DBLIB or ODBC) with the HP SQL environment
(NonStop SQL/MP).
