Adminer vs DbSchema

The installation and Adminer itself only requires a single PHP file. Once it's uploaded you can log in and start using it.

It supports several database management systems (Postgres, SQLite, Oracle, MS SQL and of course MySQL).

Anyone who uses the views function will appreciate Adminer better. You can click on a view and edit to change the view. In phpMyAdmin, you can edit a view, but it's not easy or intuitive. SQL Buddy doesn't have any way of doing this.

Has a great variety of themes which transfers pretty ugly application into a great looking one.

No need to install, it's available to use out of the box.

Includes the possibility to edit tables and data directly in the diagram without writing SQL statements.

Runs on Windows, Mac, and Linux.

If the Database schema is missing real foreign keys, it is possible to create virtual ones to be used within the tool.

Includes the possibility to generate random numerical data or fetch random entries from a text file to populate the database.

Includes the possibility to generate an ER diagram from an existing database.

Includes an SQL editor with syntax highlighting and code completion feature.

Includes a visual query editor capable of using different join types, filters as well as the 'group by' clause.
