SAP HANA is faster because it uses:
In-memory computing
Column-based storage
Parallel data processing
Advanced compression techniques
3. What does HANA stand for?
HANA stands for High-Performance Analytic Appliance.
4. Is SAP HANA a database or an application?
SAP HANA is primarily a database, but it also acts as a platform for developing and running applications.
5. What are the key features of SAP HANA?
Real-time analytics
In-memory processing
High data compression
Predictive analytics
Integrated OLTP and OLAP
SAP HANA Architecture Questions

Attribute View
Analytic View
Calculation View
13. What is an Attribute View?
Attribute Views are used for descriptive master data like customer or product details.
14. What is an Analytic View?
Analytic Views are used for transactional data and include measures and attributes.
15. What is a Calculation View?
Calculation Views combine multiple tables and views using joins, unions, and calculations. They are the most powerful and widely used.
16. Difference between Analytic View and Calculation View?
Analytic Views are limited and deprecated, while Calculation Views support complex logic and are recommended.
SAP HANA SQL & Scripting Questions
17. What is SQLScript?
SQLScript is SAP HANA’s procedural extension of SQL used for complex calculations.
18. What are Stored Procedures in SAP HANA?
Stored Procedures are reusable SQLScript programs executed on the database server.
19. What is a Table Function?
A Table Function returns a result set and can be consumed in calculation views.
20. What is CE Functions?
CE (Calculation Engine) functions improve performance by pushing calculations to the database layer.
SAP HANA Administration Interview Questions
21. What is SAP HANA Studio?
SAP HANA Studio is an Eclipse-based IDE used for administration, modeling, and development.
22. What is a Schema in SAP HANA?
A schema is a logical container that holds database objects like tables, views, and procedures.

Authentication verifies user identity using passwords, SSO, or LDAP.
28. What is Authorization?
Authorization determines what actions a user can perform after authentication.
29. What is Analytic Privilege?
Analytic Privileges restrict data access at row-level security.
30. Difference between Role and Privilege?
Privileges grant access to objects, while roles group multiple privileges.
SAP HANA Performance & Optimization Questions
31. How do you improve SAP HANA performance?
Use Calculation Views
Avoid unnecessary joins
Push calculations to database
Use proper data types
32. What is Delta Storage?
Delta Storage temporarily stores write operations before merging with main storage.
33. What is Merge Process?
The merge process moves data from delta storage to main storage.
34. What is Data Compression in SAP HANA?
SAP HANA compresses data using dictionary encoding to reduce memory usage.
