SAP BODS Architecture - SAP BODS

What is SAP BODS Architecture?

In this section, we will learn about the SAP BODS architecture. The illustration displays the architecture of BODS system with performing area.

Source Layer

The source layer contains different data sources like SAP presentations and non-SAP RDBMS system and data integration takes place in performing area.

SAP Business Objects Data Services contains different modules like Data Service Designer, Data Services Management Console, Repository Manager, Data Services Server Manager, Work bench, etc. The target system can be a DW system like SAP HANA, SAP BW or a non-SAP Data warehouse system.

You can also divide BODS architecture in the following layers −

  • Web Application Layer
  • Database Server Layer
  • Data Services Service Layer

The following illustration displays the BODS architecture.

Product Evolution – ATL, DI & DQ

Act Technology Inc. established SAP Business Objects Data Services and later Business Objects Company learned it. Act Technology Inc. is a US founded company and was responsible for development of first-data integration platform. The two ETL software products developed by Act Inc. was the Data Integration (DI) tool and the Data Management or Data Quality (DQ) tool.

Business Objects, a French company learned Act Technology Inc. in 2002 and later, both the produces were renamed as Business Objects Data Integration (BODI) tool and Business Objects Data Quality (BODQ) tool.

SAP developed Business Objects in 2007 and both the products were renamed as SAP BODI and SAP BODQ. In 2008, SAP integrated both the yields into single software product named as SAP Business Objects Data Services (BODS).

SAP BODS offers data integration and data management clarification and in the earlier version of BODS, the text data-processing solution was included.

BODS – Objects

All the objects that are used in BO Data Services Designer are called Objects. All the objects like projects, jobs, and metadata and system functions are kept in the local object collection. All the objects are hierarchical in landscape.

The objects mainly hold the following −

  • Properties − they are used to describe an object and do not affect its operation. Example − Name of an object, Date when it is created, etc.
  • Options − which control the operation of objects.

Types of Objects

There are two types of objects in the system − Reusable objects and Single Use objects. The type of object controls how that object is used and saved.

Reusable Objects

Most of the objects that are kept in the repository can be reused. When a reusable object is defined and saved in the local repository, you can reuse the object by generating Calls to the explanation. Each reusable object has only one explanation and all the calls to that object refer to that classification. Currently, if description of an object is changed at one place you are changing the object explanation at all the places where that object performs.

An object library is used to hold object explanation and when an object is dragged and dropped from library, a new reference to an existing object is created.

Single Use Objects

All the objects that are defined specifically to a job or data flow are known as single use objects. For instance, specific transformation used in any data load.

BODS – Object Hierarchy

All the objects are hierarchical in landscape. The following illustration displays the object hierarchy in SAP BODS system –

BODS – Tools & Functions

Created on the architecture illustrated below, we have many tools defined in SAP Business Objects Data Services. Each tool has its own function as per system landscape.

At the top, you have Information Platform Services connected for users and rights security management. A BOD depends on Central Management console (CMC) for user access and security article. This is applicable to the 4.x version. In the previous version, it was done in Management Support.
