Which program is the best to create online database?

I would have to say mySQL...simply because it is open-source and is well documented to make it easier for beginners like yourself... Actually PHP is also good, so it depends on which one you want to use

That is something I wanted to do... but so far... I have been too lazy to do it. I believe that mySQL is the most popular one. You can either learn it online by getting yourself a hosting service which offers you a database as part of the package. They supply all the software that you need. Or you can do it on your own computer. All the software is free. You just need to download it and install it. You need to install - The Apache server - PHP - mySQL Lots of reading to get it all working.

For online database applications, I would recommend using PHP and MySQL. The database engine is MySQL and you build the webpage with embedded PHP scripts. MySQL can also be partnered with Java. Nevertheless, for me, I would prefer the use of PHP because the codes are really written to be compatible with the web development.
