Answer 1

Normalization is a philosophy. Some people think it fits their database approach, some don't. Many modern database solutions even focus on denormalization to improve speeds.

Normalization often doesn't improve speed. However, it greatly improves the simplicity of accessing and writing data. For example, if you wanted to add a request, you would have to write a completely new JSON field. If it was normalized, you could simply add a row to a table.

In normalization, "array of dictionaries in JSON string format" is always bad. Array of dictionaries can be translated as list of rows, which is a table.

If you're new to databases: NORMALIZE. Denormalization is something for professionals.
