NO.12 Why do you create calculation views of data category DIMENSION with type TIME?

To provide additional time-related navigation possibilities

To add a temporal condition to a join to find matching records from two tables based on a date

To store historical versions of attributes

To provide the time intervals required by time-dependent parent-child hierarchies

NO.13 Which of the following techniques can you use to improve the performance of calculation views?Note: There are 2 correct answers to this question.

Partition large tables.

Limit the number of stacked calculation views.

Implement union pruning.

Avoid aggregating data early in the data flow.

NO.14 You combine two tables in a join node using multiple columns in each table.Why do you enable the dynamic join option?Note: There are 2 correct answers to this question.

To ensure that the join execution only uses the join columns requested in the query

To ensure that the aggregation always happens after the join execution

To force the calculation at the relevant level of granularity, even if this level is not the grouping level defined by the query

To allow data analysis at different levels of granularity with the same calculation view

NO.15 What are some of the restrictions that apply when defining parallelization blocks in calculation views?Note:
There are 2 correct answers to this question.

The block must start with a node that defines a table as a data source.

Multiple blocks can only be defined within a single calculation view.

The block must only have one start node.

Only one block can be defined across a stack of calculation views.

NO.16 Why do we use Git when modeling calculation views?Note: There are 2 correct answers to this question.

To manage versions of source files

To display dependencies in stacked scenarios

To automate the build process

To enable collaboration between developers

NO.17 You import a project that includes an SAP HANA database (HDB) module to your workspace. You need to create a calculation view that uses data from a table located in an external schema within the same local database.Which of the following items do you need?Note: There are 2 correct answers to this question.

Authorization

Synonym

SQL view

Remote source

NO.18 You are building a new calculation view A that uses calculation view B, as shown in the diagram. When you preview the calculation view A, the Account Number is not masked.

What could be the reason?

You previewed the data with the technical user in SAP Web IDE for SAP HANA.

You did not define masking in calculation view A.

The UNMASKED privilege for calculation view A has been granted.

Analytic privilege _SYS_BI_CP_ALL has been assigned.

NO.19 You have generated a calculation view properties file.What does it contain?

Descriptions of all objects defined in a calculation view

All settings defined in a calculation view

Dependencies between calculation views

Documentation to support the calculation view

NO.20 Why should you define calculated column expressions using plain SQL and avoid using column engine language?

To prevent queries from unfolding

To access the full set of SQL functions

To allow imperative statements

To benefit from additional SQL optimizations

NO.21 In a calculation view, why would you choose the DEPRECATED setting?Note: There are 2 correct answers to this question.

To indicate that it should not be used as a data source to other calculation views

To lock the calculation view from further modifications

To warn developers that the calculation view is no longer supported

To ensure it is not exposed to reporting tools for consumption

NO.22 Which calendar types can be selected when creating time-based DIMENSIONS?Note: There are 2 correct answers to this question.

Julian

Gregorian

Factory

Fiscal

NO.23 You want to map an input parameter of calculation view A to an input parameter of calculation view B using the parameter mapping feature in the calculation view editor. However, the input parameters of calculation view B are not proposed as source parameters.What might be the reason for this?

You selected the wrong parameter mapping TYPE.

Your source calculation view is of type DIMENSION.

The names of the input parameters do not match.

You already mapped the input parameters in another calculation view.

NO.24 What are some best practices when developing calculation views?Note: There are 2 correct answers to this question.

Include all data flow logic within one calculation view.

Model star schemas using a sequence of join nodes.

Avoid defining joins on calculated columns.

Aggregate at the lowest possible node.

NO.25 Which tool generates and executes the SQL for a specific node of your calculation view?

Debug Query mode

Explain plan

SQL analyzer

Database explorer

NO.26 You want to join two tables in a calculation view.Why do you use a non-equi join?

Join columns need to be ignored when NOT requested by the query.

Join columns have different data types.

The number of joined columns is different in each table.

The join condition is not represented by matching values.

NO.27 What are the limitations of using a full outer join in a star join node?Note: There are 2 correct answers to this question.

It must appear in the last DIMENSION in the star join node.

It CANNOT be mixed in the same star join node with other join types.

Only one column can be included in the join condition.

It is restricted to one DIMENSION in a star join node.

NO.28 You have made changes to the design-time files of several calculation views in your DEV environment. These calculation views all belong to the same project.Before deploying your calculation views to a PROD environment, which sequence of steps is required in the DEV environment?

Build the project -> Build the HDB module

Export the HDB module -> Export the project

Activate the project -> Build the HDB module

Build the HDB module -> Build the project

NO.29 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?

Procedure

Scalar function

Anonymous block

Table function

NO.30 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 the same star join node to connect the dimensions to the fact table.

Combine the transaction tables using a join 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 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 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.

NO.31 You want to ensure that your calculation view does not give unexpected results for a query that is based on any combination of columns.What is the recommended approach for verifying the results?
