PLMX206 - NonStop SQL/MX Programming
DESCRIPTION
This course is based on SQL/MX release 2.0 (G06.23) and addresses both SQL/MP tables and SQL/MX tables. It describes the facilities available in OSS, in Guardian, and on a client PC to produce SQL/MX programs. The course includes sections on data mining and publish-subscribe. It deals with the various interfaces between Java and SQL/MX, including JDBC Type 2 and Type 4 drivers.

This course also addresses the performance aspects of SQL/MX programming.

This two-day course includes 25 scripts. These are run from the OSS (UNIX-like) environment, where SQL/MX is based. The scripts permit the user to display object names, object versions, and security settings without writing metadata queries.

Extensive hands-on labs will anchor the student's classroom learning.

Course Duration: 2 days (on-site only)

WHO SHOULD ATTEND
NonStop SQL programmers who are new to SQL/MX, as well as programmers in other SQL environments who are new to NonStop systems and any others who need a solid overview of SQL/MX programming topics.
