All relational databases can be used to manage transaction-oriented applications (OLTP), and most non-relational databases that are in the categories Document stores and Column stores can also be used for OLTP, adding to the confusion. OLTP databases can be thought of as “Operational” databases...
When comparing relational and non-relational databases, it’s important to first note that these two very different types of databases are equally useful in their own right—but for contrasting reasons and use-cases. One type of database is not better than the other type, and both relational ...
There are limits to how well relational databases can scale. In terms of sheer size, some databases have fixed limits on column lengths. If your database is built on a singlededicated server, scaling requires buying more server space, proving expensive in the long run. Also, constantly adding...
Relational vs. non-relational databases While relational databases structure data into a tabular format, non-relational databases do not have as rigid of a database schema. In fact, non-relational databases organize data differently based on the type of database. Irrespective of the type of non-...

Relational databases are the backbone of countless operational and analytic systems and interacting with those databases is a critical skill for informaticians. In this chapter, we will discuss the purpose and functionality of relational databases as well as core principles that define their operation,...
