To instantiate the dimensional objects in the database, you must deploy them. To specify the type of implementation for dimensional objects, you set the deployment option. The configuration parameter Deployment Options enables you to set the deployment option.
OWB provides the following deployment options for dimensional objects.
Deploy All: For a relational or ROLAP implementation, the dimensional object is deployed to the database and a CWM definition to the OLAP catalog. For a MOLAP implementation, the dimensional object is deployed to the analytic workspace.
Deploy Data Objects Only: Deploys the dimensional object only to the database. You can select this option only for dimensional objects that use a relational implementation.
Deploy to Catalog Only: Deploys the CWM definition to the OLAP catalog only. Use this option if you want applications such as Oracle Business Intelligence Enterprise Edition to access the dimensional object data after you deploy data only. Use this option if you previously deployed with "Data Objects Only" and now want to deploy the CWM Catalog definitions without re-deploying the data objects again.
Deploy Aggregation: Deploys the aggregations defined on the cube measures. This option is available only for cubes.
Deploying Dimensional Objects that Use a MOLAP Implementation
Dimensional objects that use a MOLAP implementation can be deployed just after you define them. You can use the Design Center or the Control Center Manager to deploy a dimensional object.
Deploying Dimensional Objects that Use a Relational or ROLAP Implementation
Before you deploy a relational or ROLAP dimensional object, ensure that the implementation details are specified. This means that the dimensional object should be bound to its implementation objects. Also ensure that the dimensional object is valid.
After you perform binding, deploy the dimensional object. Before you deploy a dimensional object, ensure that all its implementation objects are deployed. For a dimension, this includes the sequence that is used to generate the surrogate identifier of the dimension levels. Alternatively, you can deploy the implementation objects together with the dimensional object.
