## Introduction
Adminer is a minimalist database management tool distributed as a single PHP file. It replaces heavier tools like phpMyAdmin with a faster, more secure, and more portable alternative that supports multiple database engines out of the box. You deploy it by dropping one file into a web server directory.

## What Adminer Does
- Provides a web-based UI for MySQL, PostgreSQL, SQLite, MS SQL, Oracle, and MongoDB
- Lets you browse, search, insert, update, and delete rows through a clean interface
- Runs SQL queries with syntax highlighting and result export
- Manages database structure: tables, columns, indexes, foreign keys, and views
- Imports and exports data in SQL, CSV, TSV, and compressed formats

## Architecture Overview
Adminer is a single PHP file that handles authentication, connection management, schema introspection, and query execution. It uses PDO and native database extensions to communicate with different database engines. The UI is server-rendered HTML with minimal JavaScript, keeping the footprint tiny. Plugins and themes extend functionality through a simple PHP hook system, and custom CSS themes change the look without modifying core code.

## Self-Hosting & Configuration
- Deploy by copying one PHP file to any web server with PHP 5.6+ or PHP 8
- Run in Docker with the official adminer image: `docker run -p 8080:8080 adminer`
- Restrict access via web server authentication or IP whitelisting for production use
- Install plugins for features like login without password field, export to XML, or JSON editor
- Apply community themes for dark mode or branded appearances

## Key Features
- Entire application is a single PHP file under 500 KB
- Supports six database engines without separate drivers or extensions
- Plugin architecture for custom login pages, editors, and export formats
- Built-in security features: CSRF protection, rate limiting, and brute-force login prevention
- Available as a Docker image with multi-architecture support
