You have a Microsoft SQL Server Analysis Services (SSAS) instance that is configured to use multidimensional mode. You create the following cube:
Users need to be able to analyze sales by product and color.You need to create the dimension.
Which relationship type should you use between the InternetSales table and the new dimension? column for the dimension is joined indirectly to the fact table through a key in another dimension table, as shown in the following illustration. snowflake schema design. When dimension tables are connected in a snowflake schema, you can define a single dimension using columns from multiple tables, or you can define separate dimensions based on the separate dimension tables and then define a link between them using the reference dimension relationship setting. The following figure shows one fact table named InternetSales, and two dimension tables called to the InternetSales measure group using a reference dimension relationship using the Customer dimension. column for the dimension is joined directly to the fact table.C: Fact dimensions, frequently referred to as degenerate dimensions, are standard dimensions that are constructed from attribute columns in fact tables instead of from attribute columns in dimension tables. can be associated with multiple facts. In relational database terminology, this is referred to as a one-to-many relationship. However, it is frequently useful to join a single fact to multiple dimension members. For example, a bank customer might have multiple accounts (checking, saving, credit card, and investment accounts), and an account can also have joint or multiple owners. The Customer dimension constructed from such relationships would then have multiple members that relate to a single account transaction.
A.
no relationship
B.
regular
C.
fact
D.
referenced
E.
many-to-many
F.
data mining
Explanation:
A reference dimension relationship between a cube dimension and a measure group exists when the key
A reference dimension relationship represents the relationship between dimension tables and a fact table in a
Customer and Geography, in a snowflake schema.
You can create two dimensions related to the InternetSales measure group: a dimension based on the
Customer table, and a dimension based on the Geography table. You can then relate the Geography dimension
Incorrect Answers:
B: A regular dimension relationship between a cube dimension and a measure group exists when the key
E: Many to Many Dimension Relationships.
In most dimensions, each fact joins to one and only one dimension member, and a single dimension member
