KissDB is a very simple key-value NoSQL database server built for small- to medium-scale data storage needs. It offers simultaneous connections, resource locking, and a RESTful API. It has a theoretically infinite database, table, and box size depending on available disk space, mitigating one of the main hassles of SQL databases. Its intended purpose is JSON storage, but any data can be stored.
The structure is as follows:
- One KissDB server hosts an unlimited number of database objects.
- One KissDB database object holds an unlimited number of table objects.
- One KissDB table object holds an unlimited number of boxes.
A KissDB table object acts like a container of key-value pairs with the name of each box being a key and its contents being the value associated with it.
In this way, I could access the information of a given username using a request such as the one below:
GET /MyAppliation/Users/ldarling
Which might return:
{"success": true, "result": "{\"name\": \"Luke Darling\", \"email\": \"[email protected]\"}"}
Or, if the box doesn't exist:
{"success": false, "result": "Box does not exist."}
The server will eventually implement authentication, but for the moment should be hidden behind a firewall blocking outside access to its bound port. Once authentication is implemented, it should still be proxied via HTTPS using nginx or a similar server. The server must never be placed in the root of an existing web server.

KissDB currently only works on Linux and has only been tested on Ubuntu. I will never create a Windows version, even though it would be very simple to make cross-compatible, simply because Windows is inferior and not worth wasting code on.
This software is still in development and may never see a complete production-ready version. This is mainly an exercise for my own learning experience, but may find its way into being used in some of my smaller projects. If you have criticisms, please refrain from complaining to me, but instead place your corrections in the form of a commit. This is an open-source project, after all.
