Exposing properties and populating database columns

You can expose a property as a database column, and populate the new column by extracting values from the Storage Stream (BLOB or pzPVStream ) column using the Property Optimization tool in a development system. You can also use this tool to "expose" values of an embedded property by automatically creating an appropriate Index- class and Declare Index rule.

You can view the classes for which a property has been optimized on the Advanced tab of the Property form.

  1. Using the Application Explorer, expand the Data Model node and the Property list.
  2. Right-click a property name and click Optimize for reporting.
  3. Select the tables in which you want to create a dedicated database column for this property. You must select at least one table.
  4. If the property is embedded, specify the RuleSet and Version that is to contain the new Index- class, the properties in that class, and the Declare Index rule.
  5. Select whether to optimize the property now or later. If you select later, click the calendar icon to select a date within seven days of the current date to optimize the property.
  6. Click Next.
  7. Review the tables to which the property column will be added and the classes that will be mapped to each table.
  8. Click Next.
  9. Click Finish.
Note: Background processing may take minutes or longer, depending on volume, and computations in your applications involving the property value may fail or produce incorrect results until all background processing is complete.

You can view the status of your background job by clicking Configure > System > Database > Column Population Jobs.
