Quiz on MongoDB 4 new features and database updates

Check out this excerpt from the new book Learn MongoDB 4.x from Packt Publishing, then quiz yourself on new updates and features to the database.

NoSQL database technologies hit the market in the mid-2000s and have been on the rise in popularity ever since. And one of the leading database technologies is MongoDB, which ranked as the fifth most popular database technology according to Stack Overflow's "2020 Developer Survey."

MongoDB is a document-based database that doesn't have a fixed schema. It is known for its flexibility and horizontal scalability. The database is ideal for IoT management, real-time analytics, inventory and personalization.

In 2018, MongoDB updated to version 4.0, implementing some significant new features and updates to security. The new version also introduced some backward incompatibility changes that database administrators and DevOps engineers should be aware of.

New features include multiple document ACID (atomicity, consistency, isolation and durability) transaction abilities and client-side field-level encryption. The fact that previous versions of MongoDB didn't support multidocument transactions was a major criticism against the database that slowed its adoption in some corporations. The client-side field-level encryption is a major security improvement that allows users to encrypt document fields prior to transmitting data and only allows decryption by applications with the proper encryption key.
