# Distributed Database

The distributed database is used to store user data and chat records, ensuring high availability and scalability of the system.

* Database Used: Alien employs distributed databases such as Cassandra or MongoDB, capable of handling large-scale data storage and high concurrent access.
* High Availability: The database uses a multi-replication mechanism to ensure data replication and synchronization between different nodes. Even if a node fails, the data remains available.
* Scalability: The distributed database can scale horizontally. As the number of users and the amount of data increases, more nodes can be dynamically added to enhance storage and processing capabilities.
