Here comes MySQL Visual Explain, a command-line tool that transforms EXPLAIN output into a hierarchical view of the query execution plan. MySQL Visual Explain collects the output of EXPLAIN in MySQL and visualize it in treeview to make the reading more understandable. It is very useful when you have large and complex queries.

How It Works:
MySQL Visual Explain tries to reverse-engineer MySQL’s EXPLAIN output into a query execution plan, which it then formats as a left-deep tree — the same way the plan is represented inside MySQL.

Example query:
SELECT actor_id, (SELECT COUNT(film_id) FROM sakila.film JOIN sakila.film_actor USING(film_id)) FROM sakila.actor;

EXPLAIN output:

In Cebase your data is stored in lists. A list is much like a table in a traditional database like Microsoft Access or FileMaker but without the hassles of having to create primary keys, foreign keys or any other low-level database object.

Recently, Cebase has added a full data export feature that allows you to export all of the data in an application including files and images. You can always download copies of your database to your own PC or network any time you want.

With Cebase, you can:

• Create Applications – Create powerful database applications with a few clicks of your mouse.
• Explorer Your Data – Slice, dice and analyze your data and then display it any way you want to.
• Share Your Data – This powerful collaborative tool makes it easy to share data with anyone, anywhere, any time.
• Design Forms – Quickly and easily build powerful and attractive data entry forms using the built-in WYSIWYG form designer.

Cebase is easy to use, first you have to create an application, then create a new list by entering a list name and defining one or more fields to design your forms or by importing your data. Once your list is created you can start entering your data. Cebase also allows you to create relationships between lists, read here on how to create relationships.

Cebase also lets you control who has access to your data. Team members, co-workers and clients can log in and view, add, edit or delete data depending upon the rights that you grant them.

Cebase.com is 100% free to use during the the beta period. For more information on how to use Cebase, visit http://www.cebase.com.
