Q & A

What are the two main categories of databases mentioned in the transcript?

The two main categories of databases are structured data and unstructured data.

What types of databases fall under structured data?

Structured data includes relational databases, which are traditional databases like Oracle, SQL Server by Microsoft, and MySQL.

Can you name some unstructured databases?

Unstructured databases mentioned include MongoDB, Cassandra, and Couchbase.

What is a key feature of NoSQL databases?

NoSQL databases, or 'not only SQL' databases, are designed for specific purposes such as collecting, gathering, and processing time data.

Why might one choose a non-relational database over a relational one?

Non-relational databases may be chosen when the requirements involve processing unstructured data or handling large volumes of varied data types.

Which database is referred to as the de facto standard for large enterprises?
