SAP/S4ANA Database Administration
What is Sap HANA Database?
• SAP stands for Systems, Applications and Products in
Data Processing.
• SAP HANA (High-Speed Analytical Appliance)
database platform.
SAP HANA is the latest ERP Solution from SAP, which is a combination of
Hardware and Software. HANA has unprecedented adoption by the SAP
customers.
SAP HANA is latest, in-memory database, and platform which can be deployed on-
premises or cloud.
SAP HANA is a combination of hardware and software, which integrates different
components like SAP HANA Database, SAP SLT (System Landscape
Transformation) Replication server, SAP HANA Direct Extractor connection and
Sybase replication technology.

SAP HANA Database & Platform
1. SAP HANA Database – SAP HANA Database is a hybrid in– memory database.
SAP HANA Database is the heart of SAPin- memory technology. In SAP
HANA, Database table are of two types –
 Row Store
 Column Store
2. SAP HANA Platform – SAP HANA Platform is development
platform with an in-memory data store which allows the

SAP HANA Edition
There are different types of SAP HANA edition, some of them as below-
 SAP HANA Platform Edition – It provides Core database technology. It Integrate SAP
component like SAP HANA database, SAP HANA Studio and SAP HANA clients. It is for
customers who want to use ETL-based replication and already have a license for SAP Business
Objects Data Services.
 SAP HANA Enterprise Edition – It contains data provisioning (SLT, BODS, DXC) component
including core database technology. It is for customers who want to use either trigger-
based replication or ETL- based replication and do not have all of the necessary license for
SAP Business Objects Data Services.
 SAP HANA Extended Edition – It contains data provisioning (Sybase) features more than
Platform and Enterprises edition. It is for customers who want to use the full potential of all
available replication scenarios including log-based replication.

SAP HANA In-Memory Strategy
SAP HANA has many processes running on the SUSE Linux
Server. SUSE Linux server manages the reservation of memory
to all process.
When SAP HANA starts up, Linux OS reserves memory for the
program code, program stack, and static data.
OS can dynamically reserve additional data memory upon
request from the SAP HANA Server.
SAP HANA create a memory pool for managing and tracking
the consumption of memory.
The memory pool is used to store all the in- memory data and
system tables, thread stack, temporary computations and all
other data structure required for managing the database.

 Architecture S/4 Hana : SAP Fiori
SAP Fiori Is :
• Multi-devices SAP Fiori applications adapt
to the type of terminal (PC, tablet,
smartphone), and to the display screen
(size, portrait / landscape, touch)
• Role-based : access to SAP Fiori applications
is controlled by the management of SAP
user roles.
• Apps-based : Applications are provided as a
package (HCM, PP, FI,CO..)

Generale Overview
 Architecture S/4 Hana : SAP Fiori
• SAP Fiori is a user interface, which brings together a collection of business applications.
• Its main purpose is to improve productivity for the most common scenarios: transactional or
analytical (validation of purchase requests, time entry, availability check, etc.).
• It is supported by SAPUI5, which is an SAP framework including a collection of libraries that can be
used to build cross-platform applications (computer, tablet and mobile).

 Architecture S/4 Hana : CDS View
• Core Data Services (CDS) is a collection of specific languages created by SAP.
• Technically is an extension of SQL, so it inherits a data definition language (create, define , select, insert, …)
and authorization control (grant, …)
• The objective of Core Data Services is to be able to define a virtual data model directly in the ERP through
what is called the VDM (Virtual Data Model).

 Architecture S/4 Hana : SAP ABAP
• SAP S/4hana ABAP is the heart or the core of SAP.
• It presents the intermediate layer between the Fiori part and the database.
• This layer ensures the execution of programs as well as the management of transactions.
• In this layer, we find all the SAP modules (Finance, logistics, etc.)

Generale Overview
 Architecture S/4 Hana: SAP HANA Database
• SAP HANA (High performance Analytic Applicance), a combination of hardware and software, optimized
to take advantage of the latest technologies in multi-core processors and RAM.
• The S/4hana database is Hana, it was developed around “In-memory” technologies and columnar
storage.
• It is possible to manage and analyze data of various types on a very large scale and in real time. The
objective of HANA technology is to bring the inputs/outputs as close as possible to the processor by
limiting disk accesses to reduce calculation times.

What is the technologie in-memory ?
• SAP HANA allows data to be brought into memory and allows for instantaneous response to analytical needs.
This increase in speed is due to the fact that in-memory tasks run in nanoseconds (unlike physical systems
where tasks run in milliseconds).
• The “In-Memory” Data part contains only the data mounted in memory, the persistent Storage contains all your
data which is stored as follows :
- Log Volume contains information about data modifications (insert, update, delete) and directly recorded at
each commit.
- Data Volume : contains data and information as well as modeling data. Automatic savepoints are executed
between memory and storage.

What are the different types of backup ?
Full data backup It consists of copying all the files and folders on a
system. Each time you make a full backup, you store
the entire data source again.
Differential data backup It consists of storing all the data modified since the
last complete data backup.
Incremental data backup The data has changed since the last full data backup
or the last delta backup.
