02. Non-Relational Databases

When Not to Use SQL:

• Need high Availability in the data: Indicates the system is always up and there is no downtime
• Have Large Amounts of Data
• Need Linear Scalability: The need to add more nodes to the system so performance will increase linearly
• Low Latency: Shorter delay before the data is transferred once the instruction for the transfer has been received.
• Need fast reads and write

Here is a helpful blog that describes the different types of NoSQL databases. You can bookmark it to review this later too.
