Prerequisites

To use universe on HANA repository and reuse the Web Intelligence document you must have the following products installed:

SAP HANA 1.0 SP03

SAP BusinessObjects BI 4.0 FP3

Universes introduction

The universe and the Web Intelligence document provided with this document target SAP HANA server 1.0 SP3 as the minimum version.

Future SAP HANA versions may impact the universe design as HANA system tables may change.

The universe and the Web Intelligence document are ready to be consumed; you only have to change the connection information.

What is the semantic layer?

The semantic layer is an abstraction layer between the database and the business user that frees the business user from the complexity of the data structures and technical names. It enables business users to access, interact, and analyze their data regardless of the underlying data sources and their schemas.

The semantic layer encompasses the following elements: universes, query generation, query panel, and database connectivity parameters.

What is a universe?

The information design tool is an SAP BusinessObjects metadata design environment that enables a designer to extract, define, and manipulate metadata from relational and OLAP sources to create and deploy SAP BusinessObjects universes.

A universe is an organized collection of metadata objects that enable business users to analyze and report on corporate data in a non-technical language. These objects include dimensions, measures, hierarchies, attributes, pre-defined calculations, functions, and queries. The metadata object layer, called the business layer, is built on a relational database schema or an OLAP cube, so the objects map directly to the database structures via SQL or MDX expressions. A universe includes connections identifying the data sources so queries can be run on the data. The role of the universe is to provide the business user with semantically understandable business objects, such as, Customer, Country, Quarter, Revenue, or Margin. The user is then free to analyze data and create reports using the business objects that are relevant to their needs without requiring knowledge of the underlying data sources and structures.

There are two types of universe: multi-source enabled relational universes, and dimensional universes.

How do I create a universe?

With BI 4.0 and BI 4.0 FP3, both types of universes are generated using the new tool called the information design tool, an SAP BusinessObjects metadata design environment. For one of the universe types, you don’t even need to create it thanks to the direct access to BEx queries using BICS. The universe is created automatically on the BEx query to render it consumable by the analysis and reporting tools in the SAP BusinessObjects portfolio. The second type – the multi-source enabled relational universe - is created by following a four-step workflow (connection, data foundation, business layer and publication) in the information design tool.

HANA repository universe

The core material provided for HANA server auditing is the universe.

The universe is based on HANA system tables and HANA catalog tables where information models information are stored: “_SYS_BI” schema and tables / views starting with “BIMC_”

A universe is composed of 3 elements:

The connection:

A connection is a named set of parameters that define how a universe can access a relational or

OLAP database.

The data foundation: A data foundation is a schema that defines the relevant tables and joins from one or more relational databases. The data foundation becomes the basis of one or more business layers

The business layer: A business layer is a collection of metadata objects that provides an abstraction of relational database entities or OLAP cubes, understandable by a business user. Objects map via SQL expressions to an underlying data foundation, or via MDX expressions to an underlying OLAP cube. These objects include dimensions, hierarchies, measures, attributes, and predefined conditions.

The universe is the compilation of those three elements and can then be published in a BOE repository (also called CMS) or locally (file system).

Edit and published the universe components

Start InformationDesignTool.exe and create a new project (see screenshot below).

By default a project is created in the current directory on a Windows 7 platform:

C:/Users/MyUser/.businessobjects/bimodeler_14/workspace

Then copy the 3 elements under the project location folder in the file system:

Hana.cnx

Hana repository v2.dfx

Hana repository v2.blx

The connection

Edit the connection

The connection provided with this document is a SAP HANA relational connection.

Prior to consume the universe you need to edit the connection and change connection information.

To edit the connection, double-click on “Hana.cnx” object then click on “Edit” button. Change the following information (see screenshot below):

Server name:port

User name

Password

Test the connection and click on “Finish” button.

Please notice that to use the universe and query the HANA catalog, the user must have administration privileges in order to access the following schemas: _SYS_BI, _SYS_REPO and SYS.

The data foundation

Edit the data foundation

Edit the data foundation (double-click on “Hana repository v2.dfx” and check that the data foundation is pointing to the Hana connection (see screenshot below).

If the data foundation is not mapped to the Hana connection the screenshot will be as show as below.

To map the data foundation to the connection, Click on the icon and select the Hana connection.

Save the data foundation.

The data model

The data foundation is the entity relationship model and is using the following tables / views:

_SYS_BI schema:

o BIMC_CUBES

o BIMC_DIMENSIONS

o BIMC_PROPERTIES

o BIMC_VARIABLE

o BIMC_VARIABLE_ASSIGMENT

o BIMC_VARIABLE_VIEW

o BIMC_VARIABLE_VALUE

o M_USER_PERSONALIZATION

_SYS_REPO schema:

o ACTIVE_OBJECT

o INACTIVE_OBJECT

SYS schema:

o OBJECTS

o OBJECTS_DEPENDENCIES

o VIEWS

o P_OBJTYPES_

Additional tables and views are also exposed in the data foundation but are not used and not linked to other tables.

The data foundation also contains 4 different views including the master view. There is no derived table, no context and no alias table.

The following tables contain calculated columns:

BIMC_DIMENSIONS

BIMC_PROPERTIES

BIMC_VARIABLE

BIMC_VARIABLE_ASSIGMENT

ACTIVE_OBJECT

INACTIVE_OBJECT

OBJECTS

The business layer

Edit and publish the business layer

Edit the business layer (double-click on “Hana repository v2.blx”) and check that the business layer is pointing to the data foundation (see screenshot below).

If the business layer is not mapped to the data foundation then click on the icon and select the data foundation (see screenshot below).

Once all the needed modifications have been done you are ready to publish the universe.

Select the business layer in the projects pane and select the menu “Publish” then the option to a “Local Folder”.

Select the folder where to publish universes.

In order to know where to publish universes, run Web Intelligence rich client and click on the icon on the top right of the window and select the menu “Options”.

Copy the location information in front of the label “Universes:” and copy it to the universe publication location InformationDesignTool.

The business layer

The business layer contains several objects stored in the following folders:

Information Models:

o Cubes

o Dimensions

o Variables

System Catalog

o Objects

o Repository

The business layer also contains pre-defined filters dedicated to filter the BIMC_DIMENSIONS and BIMC_PROPERTIES tables.

4 measures have also been created:

Number of cubes

Number of dimensions

Number of attributes

Number of measures

Several parameters and list of values have been added to the business layer.

Finally multiple predefined queries have been created in order to help designers to use the business layer and understand what kind of questions we can ask to the HANA repository.
