What is the default view node for a cube?

• PROJECTION
• SEMANTICS
• AGGREGATION
• UNION

You have imported calculation views from SAP HANA on-premise to SAP HANA Cloud.Why should you switch calculated column expression language from column engine to SQL?

• To benefit from additional SQL optimizations
• Incorrect aggregations may be generated
• Column engine language is not supported.
• To define limits for query unfolding

In your calculation view, you want to consume a custom data source defined using SQLScript.In which type of object do you write your code?

• Scalar function
• Table function
• Anonymous block
• Procedure

You create a table function to remove historic records, sum the current total weekly working hours for each employee, and update the personnel table with the results. The deployment of the table function fails.Which of the following could be a valid reason?

• Your function includes a TRUNCATE statement.
• Your function refers to a scalar function.
• You did NOT define a valid table type.
• You did not define at least one input parameter.

Why might you use the Keep Flag property in an aggregation node?

• To ensure that the aggregation behavior defined in the aggregation node for a measure CANNOT be overridden by a query
• To exclude columns that are NOT requested by a query to avoid incorrect results
• To include columns that are NOT requested by a query but are essential for the correct result
• To retain the correct aggregation behavior in stacked views

Why would you enable Debug Query mode in a calculation view?

• To identify data sources that are not accessed by a query
• To check which database engines are invoked
• To set breakpoints and step through the execution
• To understand how tables are partitioned

In a calculated column, which object do you use to process a dynamic value in an expression?

• Variable
• Input Parameter
• Procedure
• Table function

Which of the following techniques can you use to improve the performance of calculation views?Note: There are 2 correct answers to this question.

• Avoid aggregating data early in the data flow.
• Partition large tables.
• Limit the number of stacked calculation views.
• Implement union pruning.

You want to create a star schema using a calculation view. The measures are based on columns from two transaction tables. DIMENSION calculation views provide the attributes.What is the correct approach?

• Combine the transaction tables using a star join node in a calculation view of type CUBE with star join./Use a join node to join the DIMENSIONS to the fact table.
• Combine the transaction tables using an aggregation node in a calculation view of type CUBE with star join./Use a star join node to join the DIMENSIONS to the fact table.
• Combine the transaction tables using a join node in a calculation view of type CUBE withstar join.Use a star join node to join the DIMENSIONS to the fact table.
• Combine the transaction tables using a star join node in a calculation view of type CUBE with star join.Use the same star join node to connect the DIMENSIONS to the fact table.

Why would you create SQL in calculation views?

• To implement custom logic
• To provide an alternative to graphical modeling
• To fine-tune performance
• To enable write capabilities
