If authors want to perform OLAP-style queries directly against a relational database, which Framework Manager modeling technique will a modeler use?

  1. Create regular and measure dimensions and set scope.

  2. Create shortcuts to regular dimensions and fact query subjects.

  3. Create star schema groupings for dimension and fact query subjects.

  4. Create relationships between regular dimensions andmeasure dimensions.

Explanation

OLAP-style queries against relational databases (ROLAP) are enabled in Framework Manager by creating regular dimensions for descriptive attributes and measure dimensions for numeric facts, then setting their scope appropriately. This allows dimensional analysis directly on relational sources without pre-built cubes. Shortcuts and star schema groupings are different modeling techniques, and relationships between dimensions are fundamental modeling steps, not specific to enabling OLAP queries.

AI explanation

To answer this question, you need to understand the concept of OLAP-style queries and how to perform them directly against a relational database using Framework Manager modeling techniques.

Option A) Create regular and measure dimensions and set scope. This option is correct because when authors want to perform OLAP-style queries directly against a relational database, they can create regular and measure dimensions and set the scope. By doing so, they can organize the data in a multidimensional way and perform aggregations and calculations on the data.

Option B) Create shortcuts to regular dimensions and fact query subjects. This option is incorrect because creating shortcuts to regular dimensions and fact query subjects is not specifically related to performing OLAP-style queries directly against a relational database. Shortcuts are used to create reusable objects in Framework Manager.

Option C) Create star schema groupings for dimension and fact query subjects. This option is incorrect because creating star schema groupings for dimension and fact query subjects is not specifically related to performing OLAP-style queries directly against a relational database. Star schema groupings are used to organize the data in a star schema structure.

Option D) Create relationships between regular dimensions and measure dimensions. This option is incorrect because creating relationships between regular dimensions and measure dimensions is not specifically related to performing OLAP-style queries directly against a relational database. Relationships are used to define the connections between different query subjects in Framework Manager.

The correct answer is A) Create regular and measure dimensions and set scope. This option is correct because it specifically addresses the modeling technique required to perform OLAP-style queries directly against a relational database.
