    Sunitha,

    Master data, in general, refers to data that does not over a considerable amount of time, or at least not as frequently as transaction data changes. For example, fields like Address of a customer, Name of Customer etc.

    We maintain master data in BW in seperate master data tables to reduce redundant uploads of data and also to enhance query read times. Please go through the following to learn more about the start schema, you'll get a good idea:

    Hope that helps,
