SAP HANA Studio-Overview

SAP HANA studio is the interface between HANA database and reporting layer. It is the area where we degin our muti dimentional models (ex: based on start schema – where we have fact table and dimention tables).

SAP HANA studio consists of several applications. It is also called as Perspectives (It means to see from different angle).
Currently we have four perspectives Read more

Reporting on SAP HANA

SAP HANA provides various interface reporting options

ODBO – (OLE DB for OLAP)
Requests are sent to the database via MDX (MultiDimensional eXpression language). Multidimensional reporting is available via Excel Pivot Tables. HANA ODBO drivers is available via the Other/Advanced option of the Data Connection Wizard.

ODBC – (Open DataBase Connectivity)
Requests are sent to the database via SQL (Structured Query Language). In early testing, Excel was *not* a good choice
for ODBC-based reporting since ODBC reporting is based
on MSQuery which has a limitation of 4,000 tables.

JDBC – (Java DataBase Connectivity)
Popular on Unix platforms Read more

SAP HANA Hierarchies

In SAP HANA we have 2 types of Hierarchy

1. Level Hierarchy
It’s rigid in nature, where the root and the child nodes can be accessed only in the defined order (ex: organizational sturctures)
To define a level hierarchy we need one attribute per hierarchy level.

2. Parent/Child Hierarchy
The hierarchy can be explored based on a selected parent, and there are cases where the child can be a parent. Read more

SAP HANA Replication and SLT (SAP Landscape Transformation) Replication

SAP In-Memory database requires the replication of data from a source system. There are three methods of data replication from source system to SAP IMDB.

Trigger-Based Replication
If your source is ERP system then SAP recomments using SAP Landscape Transformation (SLT) Replcator. Source can also be non-SAP system. As name suggests it updates HANA system using database triggers.

While connecting to SAP source system Replication Server uses remote function call (RFC) network communication channels and for non-SAP source system it uses database connection. SAP HANA system and SAP LT Replication Server uses database connection for communication. Read more
