C_HAMOD_2404 Exam Dumps - SAP Certified Associate Questions and Answers

To improve the performance of joins in aCUBE calculation view, the following approaches are recommended:

A. Specify the join cardinality: Defining the cardinality helps the optimizer understand the data relationships and execute the join efficiently.

B. Limit the number of joined columns: Reducing the number of columns involved in the join minimizes data processing overhead, improving query performance.

Using afull outer join(C) or avoiding inner joins (D) are less performance-optimized in most scenarios.

To consume a custom data source defined using SQLScript, you write the SQLScript logic in atable function. Table functions are used to return tabular data, which can then be consumed in calculation views for further processing and analysis.

A calculation view of data categoryDIMENSIONwith typeTIMEprovides time-related navigation possibilities, such as exploring data by year, month, week, or day. This is essential for enabling time-based reporting and analysis.

TheDEPRECATEDsetting in a calculation view serves the following purposes:

A. To warn developers that the calculation view is no longer supported: Indicates that the view is outdated and should not be relied upon.

B. To indicate that it should not be used as a data source to other calculation views: Prevents new dependencies from being created on the deprecated view.

This setting does not lock the view (C) or redirect queries (D).

The generated input parameter of the interface view allows the user to select whether to run a query on the snapshot table or the original calculation view. This capability provides flexibility, enabling users to choose between querying live data or using static data for consistent results, especially when snapshots are scheduled at specific intervals.

To verify if pruning occurs with a referential join in a calculation view:

Enable the Debug Query Mode (C):This mode helps identify which columns from the source tables are being utilized in the query execution.

Performance Analysis Mode (D):Observing which columns are mapped and analyzed in this mode indicates the impact of referential joins and whether data sources are effectively pruned.

To assign a user-provided service to your database module in an XS Advanced project, you configure it in the.yamlfile. This file is used to define the bindings between the project modules and the required services, such as user-provided services for accessing external schemas.

TheDebug Query modein SAP HANA allows you to generate and execute SQL for a specific node in your calculation view. This mode is used to analyze the behavior of individual nodes in a calculation view and troubleshoot issues such as unexpected data output or performance bottlenecks.

Ananonymous blockin SQLScript allows you to test your code without generating a persistent logic container (such as a procedure or function). This is particularly useful for quickly validating or debugging SQLScript logic in a temporary execution context.
