Configuring Database Concepts

You can configure database concept metadata properties, set in the concept editor. Also, you can configure options in the Cluster Deployment Descriptor (CDD) file, for example, to enable or disable database concepts in a processing unit.

• Configuring Database Concepts Metadata Properties
  Database concepts and their properties have metadata properties. You may need to change the metadata properties in some cases.
• Metadata Properties Reference
  Metadata Properties enable you to configure metadata information for the database concepts and their properties.
• Configuring the Database Connection
  You can configure and tune the database connection or connections required for use of database concepts using various settings.
• Database Connection Configuration Reference
  Configure the database connection for database concepts using the CDD file.
• Setting the Object Management Mode of a Database Concept
  The term mode refers to cache object management behavior. If a cache is enabled for the project, you can set objects (either globally or individually) to use one of three modes: Cache Only, Cache + Memory, or Memory Only.
• Enabling or Disabling Database Concepts in a Processing Unit
  Configure the CDD file to enable or disable database concepts for individual processing units.
