This architecture can handle a wide variety of relational and non-relational data sources. It doesn't matter if it's structured, unstructured, or semi-structured data. There are 3 approaches for constructing Data Warehouse layers: Single Tier, Two tier and Three tier. A bottom-tier that consists of the Data Warehouse server, which is almost always an RDBMS. This architecture is not frequently used in practice. It does not require transaction process, recovery and concurrency control mechanisms. If you have very large datasets, consider using Data Lake Storage, which provides limitless storage for analytics data. PolyBase can parallelize the process for large datasets. This kind of access tools helps end users to resolve snags in database and SQL and database structure by inserting meta-layer between users and database.
