In this blog, let’s understand what hot and cold data storage mean and then later let’s explore Database, Data Warehouse and Data lake.

Also, I suggest you read this article to understand Structured data, Unstructured data and Semi-structured data before we proceed.

This kind of storage is used when data needs to be accessed right away. Hot data is typically business critical information which is used for quick decision making.

Hot storage is most expensive since hot data needs to be accessed frequently.

This article will walk you through what is Structured data, Semi-structured data and Unstructured data with examples. Also, present few differences between each of them to understand even better.

Before we proceed, let’s see what is a Data and Data structure.
