Request clarification before answering.
HI Swari,
Data Modeling is the base for any MDM implementation. You need to understand the business landscape and decide on the fields you want in MDM and also model them in particular tables in MDM. SAP has provided tables of different types and you need to decide which table will suit your requirement.
Also, there might be many systems to which you will be integrating the MDM systems. However, only the global fields are genearlly takein into MDM and included in the MDM repository.
For details, I am giving some links, which will throw some light on Data Modeling aspect.
How to Handle Data Modeling in Master Data Management 5.5:
SAP Network Blog: Master Data Modeling for MDM Solution (part 1) (What is Master Data)
SAP NetWeaver - Demo Model: MDM Repositories
How to Avoid Problems with your Data Model in SAP NetWeaver MDM u2013 Dou2019s and Donu2019ts (NW7.0):
You can use the Demo repositories for your understanding and also see the last link for performance efficiency as data modeling impacts performance.
Hope it helps.
Thanks and Regards
