As the data is divided into distinct units it’s easier to develop flexible queries provided the tables can be joined in a sensible way. The SQL approach does not scale so well though as it’s not productive to setup a horizontal SQL cluster. The noSQL approach offers significant scalability benefits. Originally Answered: Speaking of BI-driven aggregations/full scans in Data Warehouse, AFAIK the SQL DBs are preferable over NoSQL. If so, how the cases with fairly big volumes should be processed? Also, at early stages when a data/structure is immature (hence, columns can change frequently) - what could the solution be? The final result, however, is homogeneous data, which can be more easily manipulated.

We use SQL in data warehouse but we need not require SQL for manipulating data in NoSql. Data warehouse consists of dimension and fact while NoSql are consist limited schema. For better or worse, the most popular taxonomy from the past 10 years divides the landscape into two classes: SQL (relational databases) and NoSQL (everything else). It's a heavy-handed distinction, akin to dividing a grocery store in to "produce" and "not produce," but it does have important implications for building and maintaining software. SQL uses a relational data model.
Let’s temporarily ignore e-commerce, database migrations, business intelligence, and data collection and processing systems. Instead let’s look at three different data storage technologies. These are NoSQL, row based, and column based databases: NoSQL – very new, lots of hype, and which really means ‘NOT ONLY SQL’

Azure Synapse is a limitless analytics service that brings together enterprise data warehousing and Big Data analytics. Both SQL and NoSQL databases have their strengths and weaknesses, and your choice will depend on the kind of application you want to build and the kind of data you want to store. Often in a large business environment where you work with different applications and types of data, you may even have to rely on both.

Any database security works on the model of CIA i.e. confidentiality, integrity, and 2019-11-07 The scalability of NoSQL databases allows one database to serve both transactional and analytical workloads from the same database. In SQL databases, usually, a separate data warehouse is used to support analytics. NoSQL databases were created during the cloud era and have adapted quickly to the automation that is part of the cloud. Also, the NoSQL approach takes advantages of the cloud-based data warehousing solution much better than the SQL approach.
