Bridge Parameters
Parameter Name | Description | Type | Values | Default | Scope | ||
File | When a CubeModel is currently loaded in IBM DB2 OLAP Center: 1. Choose 'Export...' from the 'OLAP Center' menu. 2. Type the file name for the model you are saving in the 'Export file name' text box 3. Click 'OK'. This bridge will use the generated XML file as input. |
FILE | *.xml | Mandatory | |||
Data model table design level | This option controls the design level of the imported tables. It is particularly relevant when exporting metadata to a target tool which supports two views of the model: a logical view and a physical view. Some Data Modeling tools support this concept, where you can decide if a table appears both as a physical table and as a logical entity. Some Business Intelligence tools also support this concept, where you can decide if a table appears both in the physical model and in the business view of the model. Please set the option to: 'Logical and physical' The tables to appear both in the logical view and in the physical view of the model. 'Physical' Tables to appear only in the physical view of the model. |

Physical | |||
Dimensional model object names mapping | Controls how the OLAP objects' name and business name are imported. 'default mapping' The OLAP business name is imported as logical name, and the name is imported as physical name. 'alternate mapping' The OLAP name is imported as logical name, and the business name is imported as 'User Defined Property' for this object. |
