Hello,W3Schools is great! I know you have a tutorial about SQL, but before you can use SQL you need a database. Databases are often the backend of web sites.I'd really like to see a tutorial about creating/designing databases. It would be nice if the tutorial would discuss the following matters (and more):Flat files vs multi-tablesWhat to concider when designing a database (for instance if you want to extend your database)Keys, indexes, relations, constrainsts, data types ++Unfortunately I don't not have the skills to write it myself, but I could need it :-)Would be great if you could find the time to write a really good tutorial about databasesRegards,Sven from Norway
