SAP HANA Interview questions & Answers:

1. What is SAP HANA?

Most data computations in SAP HANA are done in memory. It can be delivered as an appliance or cloud platform with a control flow logic application server. HTTP (Hypertext Transfer Protocol) allows access to the platform as a standalone application.

2. What are some features of SAP HANA?

SAP HANA features include in-memory operations, column stores, parallelism, projections, dynamic aggregation, active and passive storage, real-time analysis through SLT (SAP Landscape Transformation), and SQL (Structured Query Language) script for complex calculations.

3. What does SAP HANA mean by “dynamic aggregation”?

Dynamic aggregation eliminates the need for aggregates, saving time and space, and enhancing performance.

4. What are active and passive storage in SAP HANA?

Active and passive storage allows only the data that is currently in use, such as the current year or fiscal year, for computations.

5. How SAP HANA is built?

Base HANA architecture comprises data from SAP business suite, SAP network, and BW third-party systems. SAP business objects are used to integrate data into the system, and other applications employ SAP HANA information models for complicated data processing in reporting levels.

HANA column stores store data in columns instead of rows for improved query performance. HANA lets you add all the columns, data types, dimension length, and key status to a column store.

25. How to created restore table in HANA?

HANA restoration tables store data in rows instead of columns to speed up queries. HANA allows you to add all the columns, including data types, dimension length, and key status, to a restore table.

26. How does HANA’s model perspective import option fill tables with data?

To import data into tables in HANA’s model viewpoint, give file, delimiter, and header rows and ignore leading and trailing white spaces. Select an existing table or create a new one from the loaded source file.

27. How to setup SQL Server attribute view?

To create an attribute view in SQL Server, the author specifies join conditions, semantics, and type of key attributes.
