MongoDB is a NoSQL database. Precisey speaking, it’s a
document-oriented database. It stores arbitrarily complex key-value

year. But also information about each individual part, history of
repairs, insurance and all owners. No matter how much information you
want to keep, you just put that in a single, easily accessible document.

wonder why MongoDB is one of the most popular databases.
