FS-DBENGINE

Because fsdb was already taken. This module allows you to save data without having an actual database server. This solution is an experiment despite the fact that it is ~~theoretically stable~~ in beta.

Tree:

fsdb (Customizable name) 
│
└─── __cache (Customizable name)
│   │   saves.json (Manages the backup system)
│   │
│   └─── backup
│       │   1560377410 
│       │   1560377440
│       │   ...
│       (A folder that contains all backups called by the time they were created)
│   
└─── Database1 (Customizable name)
│    └─── Collection1 (Customizable name)
│    │      table1.json (Customizable name)
│    │      table2.json (Customizable name)
│    │      ...
│    │
│    └─── Collection2 (Customizable name)
│        │   table1.json (Customizable name)
│        │   table2.json (Customizable name)
│        │   ...
│        (Each JSON file has stringified json)
│   
└─── Database2 (Customizable name)
│   └─── Collection (Customizable name)
│   │   │   Table.json (Customizable name)
│   │   │   ...
│   │   ...
│   ...

I don't know what to think about it... Even the idea of someone who will ever try it and give their feedback happens to be miraculous.
