Quick Start to Databases 
Well my tutorial on databases is finally finished. Written, submitted, proofread, errors corrected, and now finally commited to the CVS of PHPCommunity. If I must say so I think it is pretty good and that it may help some people. It will hopefully gave the reader all the basics they need to work with any database.
Basic outline of it:
- Introduction
- Database basics
- terminology
- keys
- indexes
- granularity of data
- records are inserted and extracted in a random order
- ANSI SQL
- CREATE
- INSERT
- SELECT
- WHERE
- ORDER BY
- GROUP BY
- UPDATE
- DELETE
- Working with DB - native vs. PEAR DB
- Advantages/Disadvantages
- Connect/Select
- send a query and get results
- freeing results/closing connections
- Conclusion
Hopefully it will be put on the phpcommunity website soon.
