MongoDB

From WikiMeower

MongoDB is a NoSQL database, which is currently being used for the Meower Server. It was added to fix multiple issues with Meower's old data storing scheme, the major one being able to create duplicate accounts by changing the capitalization of a username. This new database allows Meower to implement a lot of new and cool things in the server, including multiple group chats having the same name, account IDs, and search functions.
