Data Hub

A Hub-and-spoke Approach

Hub-and-spoke approach is taken in a data hub for data integration. The

data is physically moved and re-indexed into a new system. Unlike data

lake, the data hub needs to support discovery, indexing and analytics.

Data harmonization is one of the essential elements of a data hub where

the data coming from various sources and various formats are harmonized

by reducing various asymmetries such as naming differences, structural

differences, semantic differences, etc.
