What are differences between Logical data warehousing and Virtual data warehousing?

[Former Member]

Hello All,

I am working on SAP HANA platform, to integrate 3 to 4 different data sources, to have a single source of truth.
Basically combining all the Data Sources to a Data warehouse for the analytic on the integrated data.

I came know about 2 approaches.

1. Logical Data Warehouse

2. Virual Data Warehouse

Searching for both on internet, getting confused as at some places both are defined different approaches, where as at some places they are refereed as synonymes.

Kindly help me in understanding if there is any difference between both or can be treated as same with the context of SAP HANA, Smart Data Integration, Smart Data Access etc.

Regards,

Shekhar
