SleekDB

SleekDB is a simple flat file NoSQL-like database implemented in PHP without any third-party dependencies that store data in plain JSON files. It is not designed to handle heavy-load IO operations, it is designed to have a simple solution where all we need a database for managing a few gigabytes of data. You can think of it as a database for low to medium operation loads.

Features

Stores data in plain-text utilizing JSON format, no binary conversion needed to store or fetch the data. Default query cache layer
SleekDB does not require any schema, so you can insert any types of data you want
It supports schema free data, so you can filter and use conditions on nested properties of the JSON documents

SleekDB will serve data from cache by default and regenerate cache automatically! Query results will be cached and later reused from a single file instead of traversing all the available files
