The meaning of 'Network Database' here refers to the database that allows multiple users to access it simultaneously through the network. In this document, a multi-user 'cloud database' is used to replace the single-user 'SQLite' database used in the previous document, aiming to implement a distributed file system that can be mounted on any computer on the network for reading and writing. Since SQLite is a single file database that cannot be accessed by multiple computers at the same time, a database that supports network access is needed, such as Redis, PostgreSQL, MySQL, etc., which allows a file system to be mounted and read by multiple computers in a distributed environment.

However, the real-time availability of the files is not guaranteed if the file system is shared by the above approach. Thanks to the feature that the object storage is accessible by any computer with privileges on the network, we can also access the same JuiceFS file system on different computers by simply copying the SQLite database file to any computer that needs to access the storage. The previous document 'JuiceFS Quick Start Guide for Standalone Mode ' introduces how to create a file system that can be mounted on any host by using an 'object storage' and a 'SQLite' database.
