Course overview

Learn practical techniques for designing HP NonStop™ SQL/MP databases in this 2-day course. You will learn how to map a logical design into a physical design, accommodating such physical performance considerations as partitioning, VARCHAR, SLACK, and disk caching. You will gain valuable practical experience with SQL database design. The course is 60 percent lecture and 40 percent hands-on labs using HP servers.


Prerequisites

  • Concepts and Facilities for HP NonStop Systems (U4147S) and
  • HP NonStop SQL/MP Essentials (U4181S) and
  • Basic understanding of the relational approach to database design

Audience

  • Database designers
  • Database administrators
  • Application programmers
  • Analysts

Course objectives

At the conclusion of this course you should be able to:

  • Identify site requirements that impact physical design decisions
  • Identify the characteristics and selection criteria of various table types
  • Understand primary keys, considerations when slecting them, and performance implications
  • Identify advantages and disadvantages of implementing indexes and their performance implications
  • Understand the implications of using default parameters and how they impact design decisions
  • Understand the advantages and disadvantages for using partitioned tables and the different methods available to implement them
  • Understand the impact of disk cache and I/O performance
  • Describe the advantages and disadvatages for using the VARCHAR data type and SLACK parameter
  • Identify tools that can be used to assist in physical database design

Benefits to you

  • Optimize your database performance by knowing how to minimize disk input/output, processor time, and disk storage
  • Know the factors that influence physical database design decisions and apply them to your data center environment
  • Gain valuable hands-on experience with designing databases, implementing and modifying the design, and measuring whether a design change improves application performance
