In SAP HANA, a DECISION table is a tabular REPRESENTATION of the decision-making process. It doesn’t portray static solutions or ANSWERS, and standardized the logical process and allows developers to insert the values in both the ACTIONS and conditions related to the decision.

In SAP HANA, the CE functions or Calculation ENGINE PLAN Operators are specially OPTIMIZED for HANA and can perform better compared to SQL statement.

In SAP HANA, calculation VIEWS are used by developers to consume attribute and other calculation views. They are ALSO used to perform very complex calculations.

There are TWO methods available to create calculation view in SAP HANA:

• SQL Editor
• Graphical Editor

Here are the advantages of SLT REPLICATION:

• It allows DATA replication from multiple system sources to ONE HANA system and one source system to various HANA systems
• It uses a TRIGGER based approach and has no measurable performance impact on the source system.
• It offers data filtering and TRANSFORMATION capability before HANA database loading.

SAP HANA has six types of Join methods AVAILABLE with it. Inner Join: It SELECTS the set of records matching in both the table.

• Left Outer Join: This Join selects the complete set of records from the FIRST table while matching a record from the second table if available.
• Right Outer Join: It works opposite to Left Outer Join. It selects the complete set of records from the second table while matching a record from the first table if available.
• Full Outer Join: This Join selects all the records available from both the table.
• Referential Join: Works with the same PRINCIPLE as the Inner Join by confirming a maintained referential entity maintained between the two tables.
• Text Join: It is used to select LANGUAGE specific specifications.

In SAP HANA, PACKAGE is used by developers to group TOGETHER related content objects in SAP HANA Studio. It only contains sub-PACKAGES and cannot include REPOSITORY objects. A package consists of both SUN packages and repository objects.

There are three types of VIEWS available in SAP HANA, which are as follows:

• Attribute views: It provides descriptive data about the characteristics of data in the USER database.
• Analytic views: It CONSTRUCTS a central master “fact table” with key figures.
• Calculation views: It provides a way to do COMPLEX, flexible logic in the database.

In SAP HANA, CATALOG REPRESENTS the SAP HANA’s data dictionary which includes all data structures, data, and TABLES which can be used. All the views and physical tables can be found under the catalog nod.

In SAP HANA, the master controller is used to create the DATABASE triggers and ALSO for logging the table into the source SYSTEM. A crucial role is played for the creation of the synonyms.

• Special dictionary tools for Eclipse
• Optimizations in HANA
• Introduction of common ABAP programming for analytical and transactional applications
• Support for Industry 4.0 scenarios
• Support of Eclipse 4.4 and Java 8 for SAP NetWeaver Developer Studio
• Support for BIG Data
• Stable kernel
• In-app extensibility for S/4HANA

These above-mentioned SAP HANA interview questions and answers are suitable for both EXPERIENCED as well as freshers.

In SAP HANA, Schema is used to CATEGORIZE database content according to CUSTOMER defined GROUPINGS which have a particular meaning for users. It ALSO helps to determine access RIGHTS to the database objects.

There are three types of Schema used in SAP HANA:

• User Defined Schema
• System Defined Schema
• SLT Derived Schema

Here are system requirements to install SAP HANA:

• CPU: Intel Xeon E5 – 26xx v2/v3 or Intel Xeon E7 – x8xx v1, 8 cores minimum, up to 1.5TB, 2 socket, and scale up only.
• RAM: minimum of 128 GB Ram to max memory supported by the system.
• Drives & STORAGE: Minimum 2 times of the memory.
• Operation system: SUSE Linux Latest or Red Hat Linux Latest

Here is the list of different data types used in SAP HANA.

• Date Times Types
• Numeric Types
• Boolean
• Character String
• Binary Types
• Large Object Types
• Multi-valued Types

SAP HANA Studio is an Eclipse-based IDE (Integrated Development Environment) which is used to develop artifacts in a HANA server. It enables technical users to manage the SAP HANA database better, to CREATE new or modify existing data models and to develop and maintain user authorizations.

A set of GLOBAL interviewer CHOSEN SAP HANA interview QUESTIONS as their best choice to be asked in the interviews.

Here are a few of the CRUCIAL advantages of using SAP HANA:

• ACQUIRE customer-centric application
• Enhanced USER experience
• Optimum data management
• A centralized PROCESS for fewer settlement issues
• Possibility to EXTEND the ability of HANA

SAP HANA platform replicates and ingests structured data from both SAP and non-SAP relational databases, applications and other SYSTEMS rapidly. It uses in-memory database technology which ALLOWS the processing of massive amounts of real-time data in a shorter time period. SAP HANA is used to process an enormous amount of data in a short time. It also can be used to treat data stored in RAM as opposed to reading it from a DISK.
