With relational database systems, you use tables to store and manage information. This sounds simple but involves quite complex concepts such as normal forms, key relationships, and JOINs. This article will introduce the basics of the relational database model, compare its advantages and disadvantages, and delimit this type of data storage from alternative approaches, like object databases,…

Databases are usually based on rows of data. Columnar databases turn this system on its side. Instead of saving each entry one after the other, in a columnar database entries are stored category by category. This results in a decisive speed advantage when working with massive quantities of data. But how exactly does a column-oriented DBMS work?
