Informix 11.7 Database Administration - SPVC


DURACIÓN: 32 Hours

Precio: €950,00


This course will teach the student the basic concepts of data management within IDS. It discusses how to determine correct data types; how to create, manage and maintain tables and indexes; how the IDS optimizer works; how to manage data; and how to utilize the SET EXPLAIN feature to determine query effectiveness.

The course is updated for version 11.50 of Informix, but is suitable for those still running previous versions of IDS. This course is the Self Paced Virtual version of classroom-delivered course Informix Dynamic Server 11 Performance Tuning (IX221) and Instructor Led OnLine course Informix Database Administration: Managing and Optimizing Data - SPVC (3X221).

If you are enrolling in a Self Paced Virtual Classroom or Web Based Training course, before you enroll, please review the Self-Paced Virtual Classes and Web-Based Training Classes on our Terms and Conditions page, as well as the system requirements, to ensure that your system meets the minimum requirements for this course.


  • Select the IBM IDS data types appropriate for storing your data
  • Create and maintain databases, tables, and indexes
  • Estimate size and extent requirements for tables and indexes
  • Create index strategies to improve performance
  • Create and maintain table and index partitioning (fragmentation)
  • Implement referential and entity integrity
  • Manage database and table modes
  • Manage violations logging
  • Describe how the optimizer builds an optimal query plan
  • Use the SET EXPLAIN feature to capture optimizer query plans
  • Use directives and environment variables to influence the optimizer
  • Optimize the query plan through the use of UPDATE STATISTICS
  • Manage end-user concurrency
  • Use permissions and roles to manage data security
  • Create and use views
  • Manage smart large objects
