Verysimple DB Reflector
=======================

[](#verysimple-db-reflector)

DB Reflector inspects a database schema and converts it into a simple collection of arrays and objects that can be easily inspected. This includes information about columns, keys and table relationships.

DB Reflector neutralizes vendor-specific information and provides a consistent schema for all supported databases. Some possible uses for this Reflector are for building a generic DB editor or a code generator.

Databases currently supported are MySQL and Postgres. SQLite is being worked on.

Available on [packagist.org](https://packagist.org/packages/verysimple/db-reflector).

Installation
------------

[](#installation)

```

```

Usage
