SAP BODS - Data Services Designer

---

Data Services Designer is a developer tool, which is used to create objects consisting of data mapping, transformation, and logic. It is GUI based and works as a designer for Data Services.

Repository

Repository is used to store metadata of objects used in BO Data Services. Each Repository should be registered in Central Management Console and is linked with single or many job servers, which are responsible for executing jobs that are created by you.

Types of Repositories

There are three types of Repositories.

• Local Repository − It is used to store the metadata of all objects created in Data Services Designer like projects, jobs, data flow, work flow, etc.

• Central Repository − It is used to control the version management of the objects and is used for multiuse development. Central Repository stores all the versions of an application object. Hence, it allows you to move to previous versions.

• Profiler Repository − This is used to manage all the metadata related to profiler tasks performed in SAP BODS designer. CMS Repository stores metadata of all the tasks performed in CMC on BI platform. Information Steward Repository stores all the metadata of profiling tasks and objects created in information steward.

Job Server

Job server is used to execute the real time and batch jobs created by you. It gets the job information from respective repositories and initiates the data engine to execute the job. Job server can execute the real time or scheduled jobs and uses multithreading in memory caching, and parallel processing to provide performance optimization.

Access Server

Access Server in Data Services is known as real time message broker system, which takes the message requests, moves to real time service and displays a message in specific time frame.

Data Service Management Console

Data Service Management Console is used to perform administration activities like scheduling the jobs, generating the quality reports in DS system, data validation, documentation etc.

BODS – Naming Standards

It is advisable to use standard naming conventions for all the objects in all systems as this allows you to identify objects in Repositories easily.
