Database Reference
In-Depth Information
Data formats and access patterns are diverse which additionally drives some of the
need for various platforms. Any new strategic enterprise application development
should not assume the persistence requirements to be relational. For example, data
that is transactional in nature could be stored in a relational store and twitter feed

Master and Reference data : Though we see Master data and Reference
data categorized under the same bucket, they are different in their own
