Data Estate reframes the notion that data is no longer a byproduct or just an accidental creation of business processes or the storage of information.
A Data Estate is a much broader concept and collection of data storage locations that might exist out of (operational) databases, data warehouses, data marts and data lakes, which each of them might be either on-premise or in the Cloud and require all sorts of data manipulation and data movement functionality including ETL, syncing, real time data bus, … between them.
