1. What is a calculation view in SAP HANA?
o A) A view that only displays data from a single table
o B) A database object that can perform complex calculations and
aggregations
o C) A view used solely for data retrieval without any calculations
o D) A temporary table used for staging data
o Answer: B) A database object that can perform complex calculations
and aggregations
o Explanation: Calculation views are advanced database objects in SAP
HANA that allow users to perform complex calculations and data
manipulations using various nodes.
2. Which node type in a calculation view is primarily used to join data from
different sources?
o A) Projection Node
o B) Join Node
o C) Union Node
o D) Aggregation Node
o Answer: B) Join Node
o Explanation: The Join Node in a calculation view is specifically
designed to combine data from multiple sources, enabling complex
data models.
3. In a calculation view, what is the primary purpose of a Projection Node?
o A) To aggregate data
o B) To join multiple tables
o C) To define which columns to include in the final output
o D) To filter rows based on a condition

o Answer: C) To define which columns to include in the final output
o Explanation: The Projection Node allows the developer to select
specific columns from the underlying tables, thus determining the
structure of the final result set.
4. What type of calculation view allows for the creation of hierarchies and
enables data aggregation?
o A) SQL View
o B) Graphical Calculation View
o C) Analytical Calculation View
o D) Table View
o Answer: C) Analytical Calculation View
o Explanation: Analytical Calculation Views are designed to support
complex calculations, aggregations, and hierarchies, making them
suitable for OLAP operations.
5. Which of the following nodes is used to perform aggregations in a
calculation view?
o A) Union Node
o B) Join Node
o C) Aggregation Node
o D) Projection Node
o Answer: C) Aggregation Node
o Explanation: The Aggregation Node is used to summarize data and
perform calculations such as SUM, COUNT, and AVG.
6. What is the significance of the “Semantics” section in a calculation view?
o A) It defines how the data is physically stored.
o B) It specifies the relationships between different nodes.

o C) It helps in defining measures and dimensions for reporting.
o D) It allows for data transformation before loading.
o Answer: C) It helps in defining measures and dimensions for
reporting.
o Explanation: The Semantics section is crucial for reporting purposes
as it determines how data should be interpreted and displayed in
analytics tools.
7. When creating a calculation view, what is the maximum number of joins
allowed?
o A) 5
o B) 10
o C) 20
o D) No specific limit
o Answer: D) No specific limit
o Explanation: SAP HANA does not impose a specific limit on the
number of joins in a calculation view; however, performance
considerations may dictate practical limits.
8. In a calculation view, which node would you use to stack data from two
similar tables?
o A) Join Node
o B) Union Node
o C) Projection Node
o D) Aggregation Node
o Answer: B) Union Node
o Explanation: The Union Node is designed to combine the result sets
of two or more tables with similar structures, stacking the data
vertically.

9. What type of calculation view is best suited for OLAP scenarios?
o A) Calculation View
o B) Analytical Calculation View
o C) Graphical Calculation View
o D) SQL Calculation View
o Answer: B) Analytical Calculation View
o Explanation: Analytical Calculation Views are optimized for Online
Analytical Processing (OLAP) tasks, supporting advanced calculations
and aggregations.
10. Which of the following is NOT a characteristic of a Calculation
View?
o A) Can contain multiple nodes
o B) Can aggregate data
o C) Must always be created in SQL script
o D) Can be consumed by SAP Analytics Cloud
o Answer: C) Must always be created in SQL script
o Explanation: Calculation Views can be created using both graphical
and SQL script methods, so they are not limited to SQL script.
11. What is the primary function of the Filter Node in a calculation
view?
o A) To merge data from multiple sources
o B) To apply conditions to the data before processing
o C) To calculate measures and dimensions
o D) To format the output of the data
o Answer: B) To apply conditions to the data before processing
