High Performance Application Design on Db2 z/OS

Duration: 3.0 days

Method: Instructor led, Hands-on workshops

Price: $1800.00

Course Code: DB1051

Audience

Db2 Developers, Database Administrators, Db2 Project Leaders and Analysts, and Application Personnel who will be designing, coding, and implementing Db2 Databases and Application Systems.

Description

Implementing logical database and physical design on Db2 for z/OS requires an understanding of the inner workings of this platform and an understanding of the application processing the data. Learn and discuss some of the things to consider when making this transition in this action packed course. Application design is as critical a part of high performance design as the logical and physical aspects of a database application. Design considerations for high performance will involve logical design, physical design, and application considerations. This is a great course for developers and others to understand everything involved to get peak performance.
