What are NoSQL databases?
Although relational databases are used widely in the industry, they still have some limitations. One of the most severe limitations of relational databases is that each item can only contain one attribute. But there is often a need to store several related items in one "row" of data in the same table. With growing and changing data, relational databases can face issues with scalability.
I think the statement "One of the most severe limitations of relational databases is that each item can only contain one attribute" is not precisely accurate. In the context where we refer to columns as attributes, it wouldn't make sense and could be confusing.
In the reference article that mentions this statement, there is an example that makes it clearer what the author means by attribute. It could be helpful to either include an example or rephrase the statement.
