What is SAP HANA

SAP HANA

HANA stands for high-performance analytic appliance. SAP HANA is an application that uses in-memory database technology that allows the processing of massive amounts of real-time data in a short time. The in-memory computing engine allows HANA to process data stored in RAM as opposed to reading it from a disk. This allows the application to provide instantaneous results from customer transactions and data analyses.

SAP HANA is designed to process structured data from relational databases, both SAP and non-SAP, and applications and other systems rapidly. It is capable of using three styles of data replication depending on the source of the data - log-based, ETL-based and trigger-based. The relocated structured data is stored directly in memory. Because of this, data can be accessed quickly in real time by the applications that use HANA.

                                   

SAP HANA supports various use cases for real-time analytics. Few examples are:

• Monitoring and optimization of telecommunications network
• Supply chain and retail optimization
• Fraud detection and security
• Forecasting and profitability reporting
• Energy use optimization and monitoring

SAP HANA is a data warehouse appliance for processing high volumes of operational and transactional data in real-time. HANA uses in-memory analytics, an approach that queries data stored in random access memory (RAM) instead of on hard disk or flash storage.

A HANA appliance uses an SAP Sybase replication server to copy and synchronize data from an SAP data warehouse or enterprise resource planning (ERP) application in real-time.  By running in parallel to the source SAP ERP application, HANA allows business users to query large volumes of data in real-time without having to wait for scheduled reports to run.

HANA supports industry standards such as structured query language (SQL) and multi-dimensional eXpressions (MDX).  It also includes a programming component that allows a company's IT department to create and run customized applications on top of HANA.  According to SAP, HANA has the ability to scan 500 billion point of sale (POS) records in seconds. SAP HANA was previously called SAP High-Performance Analytic Appliance.

INTRODUCTION TO SAP HANA

SAP HANA combines database, data processing, and application platform capabilities in-memory and the platform provides libraries for predictive, planning, text processing, spatial, and business analytics.

While eliminating data redundancy and latency, the new architecture enables converged OLTP and OLAP data processing within a single in-memory column-based data store with ACID compliance. SAP HANA has become the most suitable platform for building and deploying next-generation, realtime applications and analytics. It provides advanced capabilities, such as predictive text analytics, spatial processing, data virtualization, on the same architecture, besides simplifying application development and processing across big data sources and structures.

At its core, it is an innovative in-memory relational database management system that makes full sense of the capabilities of current hardware to increase application performance, to reduce cost of ownership, and to enable new scenarios and applications that were not possible before.

Components

• SAP HANA is the introduction of SAP AG, in-memory database technology. There are five components in the Software Group
• SAP HANA DB (or HANA DB) refers to the technology of the database
• SAP HANA studio refers to a set of tools provided by SAP for modeling
• SAP HANA Appliance relates to HANA DB supplied as a partner of certified equipment as a unit. It also includes tools for modeling of HANA studio, as well as replication tools and data conversion to move the data into the database HANA
• SAP HANA Application Cloud refers to a cloud infrastructure for application delivery (usually existing SAP applications rewritten to run on HANA).

SAP HANA CONSULTANT CAREER

To take up a career in HANA there are several areas one can specialize in such as SLT, which is the data replication tool which replicates source system tables into HANA, HANA modeling to build the basic models which reports sit on, Data Services, Security, etc.

Required certifications

SAP offer two main certification paths.

• Path is for administration and operations and is considered more technical
• Path is for implementation and modeling.

Job Outlook

Given SAP’s grasp on the market for high-end ERP installations, the slice of this market for certified SAP professionals will continue to grow.  Although Foote Partners’ research indicates that some SAP consultants can earn high-paying jobs without certification, targeted technical training and project management experience helped the industry’s top earners avoid salary erosion through the economic downturn.

According to government research packages for many SAP consultants in the early stages of their careers are similar to those of computer support specialists who often earn between $33,000 and $55,000 per year.

SAP consultants with specialized certifications and industry experience play a variety of roles including project planning, deployment, and analysis. Based on an employer’s industry and location, these jobs often pay between $58,000 and $96,000 annually.

Interview Questions On SAP HANA

• 1. Define Five-minute rule ?

It is a rule of thumb for deciding whether a data item should be kept in memory, or stored on disk and read back into memory when required. The rule is “randomly accessed disk pages of cache are re-used every 5 minutes”.

• 2. Define multi-core CPU ?

Multiple CPU’s on one chip or in one package is called multi-core CPU. 

• 3. Define Stall ?

Waiting for data to be loaded from main memory into the CPU cache is called as Stall.

• 4. What is SAP In-Memory Appliance (SAP HANA) ?

HANA is an in-memory technique to store data that is particularly suited for handling very large amounts of tabular, or relational, data with extra ordinary performance. Common databases store tabular data row-wise. Reorganizing the data in memory column-wise brings a tremendous speed increase when accessing a subset of the data in each table row.

• 5. What are the components or products of HANA ?

SAP HANA contains the following components.

 1. SAP HANA DATABASE

2. SAP HANA Studio SAP HANA CLIENT

3. SAP HANA INFORMATION COMPOSER

4. DIAGNOSTIC AGENT 7.3

5. SAP HANA client package for MS excel

6. SAP HANA UI for Information Access (INA)

7. SAP HANA AFL 1.0

8. Software Update Manager for SAP HANA

9. SAP LT Replication Add On

10. SAP LT Replication Server

11. SAP HANA Direct Extractor Connection (DXC)

12. SAP Data Services 4.0

• 6. What are the different editions available in HANA appliance software ?

Platform Edition:

Platform edition is intended for customers who want to use ETL-based replication and already have a license for SAP BO Data Services.

Enterprise Edition:

Enterprise edition is intended for customers who want to use either trigger-based replication or ETL-based replication and do not already have all of the necessary licenses for SAP BO Data Services.

• 7. What is columnar and Row-Based Data Storage ?

A database table contains data in the form of rows and columns. However Computer memory is organized as a linear structure. To store a table in linear memory, there are two options. A row-based storage stores a table as a sequence of records, each of which contains the fields of one row.  In a columnar storage the entries of a column are stored in contiguous memory locations. The SAP HANA database allows specifying whether a table is to be stored column-wise or row-wise. It is also possible to alter an existing table from columnar to row-based and vice versa. Search operations in tabular data can be accelerated by organizing data in columns instead in rows.

• 8. What are the advantages of Column based tables ?

The advantages of column based tables are: 

1. Calculations are typically executed on single or a few columns only.
2. The table is searched based on values of a few columns.
3. The table has a large number of columns.
4. The table has a large number of rows and columnar operations are required (aggregate, scan, etc.).
5. High compression rates can be achieved because the majority of the columns contain only few distinct values (compared to number of rows). 
• 9. What are the advantages of Row-based tables ?

The advantages of Row based tables are:

1. The application needs to only process a single record at one time (many selects and/or updates of single records).
2. The application typically needs to access a complete record (or row).
3. The columns contain mainly distinct values so that the compression rate would be low.
4. Neither aggregations nor fast searching are required.
5. The table has a small number of rows (e. g. configuration tables). 
• 10. Which case the data to be stored in columnar storage ?

To enable fast on-the-fly aggregations, ad-hoc reporting, and to benefit from compression mechanisms it is recommended that transaction data to be stored in a column-based table.

• 11. What is paralelization ?

Column-based storage makes it easy to execute operations in parallel using multiple processor cores. In a column store data is already vertically partitioned means that operations on different columns can easily be processed in parallel. If multiple columns need to be searched or aggregated, each of these operations can be assigned to a different processor core. In addition operations on one column can be parallelized by partitioning the column into multiple sections that can be processed by different processor cores

• 12. What are the different Compression Techniques ?

The compression techniques are:

1. Run-length encoding

2. Cluster encoding

3. Dictionary encoding

• 13. Why materialized aggregates are not required ?

With a scanning speed of several gigabytes per millisecond, in-memory column stores, make it possible to calculate aggregates on large amounts of data on the fly with high performance. This is expected to eliminate the need for materialized aggregates in many cases.

• 14. What are the advantages of Eliminating materialized aggregates ?

The advantages are:

1. Simplified data model
2. Simplified application logic
3. Higher level of concurrency and With the fly Aggregation we have aggregated values up to date
• 15. What are the different types of replication techniques ?

The replication techniques are:

1. ETL based replication using BODS

2. Trigger based replication using SLT

3. Extractor based data acquisition using DXC

• 16. Define SLT ?

SLT stands for SAP Landscape Transformation which is a trigger based replication. SLT replication server is the replication technology to pass data from source system to the target system. The source can be either SAP or non-SAP. Target system is SAP HANA system which contains HANA database.

• 17. What is Configuration in SLT ?

The information to create the connection between the source system, SLT system, and the SAP HANA system is specified within the SLT system as a Configuration. You can define a new configuration in Configuration & Monitoring Dashboard (transaction LTR).

• 18. What is Configuration and Monitoring Dashboard ?

It is an application that runs on SLT replication server to specify configuration information (such as source system, target system, and relevant connections) so that data can be replicated. It can also use it to monitor the replication status (transaction LTR).

Status Yellow: It may occur due to triggers which are not yet created successfully.

Status Red: It may occur if master job is aborted (manually in transaction SM37).

• 19. What is advanced replication settings ?

A transaction that runs on SLT replication server to specify advanced replication settings like

1. Modifying target table structures,
2. Specifying performance optimization settings
3. Define transformation rules

• 20. Define Latency ?

It is the length of time to replicate data (a table entry) from the source system to the target system.

• 21. Define logging table ?

A table in the source system that records any changes to a table that is being replicated. This ensures that SLT replication server can replicate these changes to the target system.

• 22. What are Transformation rules ?

A rule specified in the Advanced Replication settings transaction for source tables such that data is transformed during the replication process. Example you can specify rule to

1. Convert fields
2. Fill empty fields
3. Skip records
• 23. When to change the number of Data Transfer job ?

If the speed of the initial load/replication latency time is not satisfactory If SLT replication server has more resources than initially available, we can increase the number of data transfer and/or initial load jobs. After the completion of the initial load, we may want to reduce the number of initial load jobs.

• 24. What are the jobs involved in replication process ?

The replication process is consist following jobs:

1. Master Job (IUUC_MONITOR_)

2. Master Controlling Job (IUUC_REPLIC_CNTR_)

3. Data Load Job (DTL_MT_DATA_LOAD__<2digits>)

4. Migration Object Definition Job (IUUC_DEF_MIG_OBJ_<2digits>)

5. Access Plan Calculation Job (ACC_PLAN_CALC__<2digits>)

• 25. When to go for table partitioning ?

If the table size in HANA database exceeds 2 billion records, split the table by using portioning features by using “Advanced replication settings” (transaction IUUC_REPL_CONT, tab page IUUC_REPL_TABSTG).
