To begin demystifying the concept of data warehousing, we will navigate through the core principles that underpin its design and functionality. From the organization of structured data to the orchestration of complex queries, we’ll dive deeper into a data warehouse’s architecture. ...
Data mesh architecture allows data access from a number of locations rather than one central data warehouse or data lake. (It should be noted that there are situations where it is completely appropriate to build a central data lake as an additional part of the data mesh system.) ...
