Description

MongoDB is one of the most in demand databases around despite being relatively new to the scene. In fact, MongoDB was created due to the limitations of traditional databases!

Due to the changing data demands of today and the growth in “big data”, traditional relational databases are finding it increasingly difficult to store this data and deliver performance.

MongoDB is able to handle large volumes of data while maximising performance and adopt a flexible schema approach, giving you ultimate flexibility when modelling data.

These are just a few of the reasons why MongoDB is rated as one of the top 5 most popular database systems in the world according to Statista (as of June 2021).

So if you work with data in any capacity and are looking to develop your experience of MongoDB then this is the perfect course for you!
