Real Time Analytics with SAP Hana

Chapter 2. SAP HANA Data Modeling Approach

This chapter gets you started with the modeling approach. We start with a discussion about row and column storage and their usage. Then, we move on to the architecture of the SAP HANA engine and understand how different views are processed. We will also discuss the different schemas available in SAP HANA. This chapter will introduce you to modeling principle and guidelines. We will perform a comparative study of different modeling artifacts in SAP HANA. We will close the chapter with a learning of the SAP HANA Studio and how to create packages and delivery units.

After completing this chapter, you should be able to:

  • Differentiate between row and column storage, and know when to use what
  • Understand basic architecture of the SAP HANA engine
  • Differentiate between modeling artifacts in SAP HANA
  • Know modeling principles
  • Learn to use the SAP HANA Studio
  • Differentiate schemas in SAP HANA
  • Create packages and delivery units

Row and column storage in SAP HANA

Relational databases typically use row-based data storage. SAP HANA uses both (row based and column based data storage)

  • The row storage: This stores records in a sequence of rows
  • The column storage: The column entries are stored in a continuous memory location

Before getting into a SAP HANA specific discussion, let's try to understand how different column storage is from row. The column-oriented database systems (in our case, SAP HANA) perform better than traditional row-oriented database systems on analytical tasks, in areas such as data warehouses, decision support, predictive analysis, and business intelligence applications.

The major reason behind this performance difference in these areas is that column stores are more I/O efficient for read-only queries as they only have to read the attributes accessed by a query from the disk or memory.

Let's see a few factors that optimize performance in the column storage:

  • Compression: The data stored in...

Basic architecture of the SAP HANA engine

SAP HANA has different engines to process different views. It has the following engines:

  • JOIN engine: This engine is for processing the JOINS (all type of joins)/attribute views
  • OLAP engine: This engine is used to process analytical view
  • CALCULATION engine: This engine is used to process complex calculation that cannot be processed by the JOIN or OLAP engine

It is the SQL optimizer, which sees the models and queries and decides which engine to call.

Any analytic view or attribute view with a calculate attribute will be processed as a calculation view. This should to be taken into consideration during modeling, because it can have a measurable impact on the performance of the data model. Different engines cooperate among themselves as well.

The following figure shows the SAP HANA engines processing different views:

Basic architecture of the SAP HANA engine

Other than the preceding illustrated engines, we do have a planning engine as well in SAP HANA. The planning engine, allows financial planning...

Different modeling artifacts in SAP HANA

Before creating a new SAP HANA modeling artifact it is of paramount importance to know which types of modeling artifacts will be suitable for our business need. Depending on the scenario you are working in, your choice might vary. Factors that should be taken into consideration are:

  • The write- or read-intensive scenario, so as to decide between column and row storage
  • Data access need and resources for the replication method available
  • The application or client to be supported with your information model as different clients expose/consume data differently
  • Performance and functionality, as not all views can give the same functionality or performance

The first thing we need to decide is do we need a column table or row store. Once we have decided, we can have a glance at the following table and choose the views, if our requirement can be fulfilled by any of these:

 

Column table

Analytical view

Calculation view (SQL)

Calculation view (CE function...

SAP HANA Studio

The SAP HANA Studio is a client tool to connect to the SAP HANA database. It is a Java-based application that runs on the Eclipse platform. It is delivered as part of the SAP HANA installation package, and provides an environment for administration, modeling, development, and data provisioning.

We will be primarily working with SAP HANA Studio for all our modeling needs in this book.

Perspectives in SAP HANA Studio

Perspectives are predefined user interface layouts with several views. We have the following perspectives:

Perspectives in SAP HANA Studio

Let's see a few of the perspectives and their usage in detail:

  • SAP HANA Administration Console: This perspective is used by SAP HANA administrators to administrate and monitor the whole SAP HANA system. We will use it to add our system to the SAP HANA instance into SAP HANA Studio.
  • SAP HANA Modeler: The SAP HANA Modeler perspective is used by data modeler to create information models and data artifacts, as a combination...

Different schemas in SAP HANA

Schemas are used to categorize database content according to customer defined groupings that have a particular meaning for users. Schemas also help to define access rights to the database objects. Schemas can help identify which tables to use when defining information models. But a model can incorporate tables from multiple schemas, which are:

  • System defined
  • User defined
  • SLT derived schemas

System defined schemas are delivered with the SAP HANA database and contain the HANA system's information. These are system schemas such as _SYS_BIC, _SYS_BI, _SYS_REPO, _SYS_STATISTICS, and so on.

Let's see more about these system defined schemas:

  • _SYS_BIC: This schema contains all the column views of activated objects. When the user activates any of the views, say the attribute view/analytical view / the calculation view, the respective runtime objects are created under the _SYS_BIC column view.
  • _SYS_REPO: This contains a list of activated objects, inactive objects...

Real Time analytic-es is one of the most attractive BI topics nowadays. This was impossible or very expensive at near past; but we can use advanced technologies like SAP HANA to achieve this dream.I was a student for the Author "Vinay Singh" by attending one of the Official SAP training. I have to say that Vinay is a very knowledgeable person who have a great skills to teach and being one whom working in SAP Labs and one of the early first people whom get the chance to see how SAP HANA started and evolved. So, I was very interested to read this book.The author did a really very good job here as he started with some introductory chapters to setup the basics which required to understand the remaining chapters. Topics like difference between traditional database and in-memory database, joins, union, procedures and scripts in SAP HANA are discussed in the first chapter. The author moves to explain SAP HANA Studio and and different modeling techniques like (attribute views, analytical views and calculation views). After that; the author start talking about data loading and how we can use replication techniques like SAP HANA SLT to instant data replication into SAP HANA.I really liked the self-study questions which added by end of each chapter; this is an amazing way to help understanding topics and do more re-search. Finally; I would like to thank the Author for his effort and looking for more great SAP HANA Books

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
