Anybody interested in creating RealAudio and RealVideo content on their sites will find it's a great deal easier than they might have initially imagined.

The instructions given below are for RealAudio on a Windows 95/98 computer, butrepparttar process is almost identical for RealVideo and other platforms. I tentatively suggest you print out this tutorial for easier reading, by copyingrepparttar 132084 text and pasting it into Wordpad or Word then printing it out. Or if, you prefer, you can downloadrepparttar 132085 text as a zipped document from here. Netscape users please press shift as you click to saverepparttar 132086 file to disc.

Before you start, be sure you:

2: check with your internet service provider orrepparttar 132088 people who provide your web space that they support streaming media. This isrepparttar 132089 one sure thing that will guarantee that you'll never get this technique to work on your site. Save your self a lot of time and effort by finding out before you start this tutorial.

3: are not violating any copyright laws by placing copyrighted material on your web site. It goes without saying thatrepparttar 132090 best files to put on your web site are files you've created yourself. A snippet ofrepparttar 132091 Spice Girls may titillate a few but it won't encourage people to stick around or even come back to see how your site develops and it may make you vulnerable to prosecution.

Step 2: Preparations to encode your music file Double clickrepparttar 132096 icon on your desktop or fromrepparttar 132097 start menu called " RealProducer." Inrepparttar 132098 dialogue box which pops up choose 'record from file'

Now you need to enterrepparttar 132099 name ofrepparttar 132100 file that you want to encode. Click "Browse" and browse forrepparttar 132101 file. Once you have foundrepparttar 132102 file, click "Open" then "Next".

Inrepparttar 132103 next screen, enterrepparttar 132104 title, author, copyright and a brief description ofrepparttar 132105 track to inform your listeners ofrepparttar 132106 kind of thing they can expect to hear when they play it.

Most servers are still susceptible to file names which aren't continuous so a file like 'wake free zone.rm' would be more easily recognised as 'wakefreezone.rm'.

Finally, RealProducer allows you to confirm your choices. If there is nothing wrong with your choices, click "Start". If you wish to change something, hit 'back' and change what you need to inrepparttar 132112 appropriate dialogue boxes.

Why Do I Need A Database?

Written by Dan Grossman

If you're not familiar withrepparttar term as it relates torepparttar 132082 web, a database is a structured collection of data. It can be anything from a list of email addresses to a set of names, addresses and phone numbers.

By farrepparttar 132083 most popular database management system is mySQL, because it is free, works well, and most web hosts have it installed. This can be used in conjunction with a language such as PHP or Cold Fusion to create a website which interacts withrepparttar 132084 database.

PHP is probablyrepparttar 132085 most popular of languages for interacting with mySQL databases. It can be easily used to create webpages for your site dynamically. This means that, rather than a site consisting of many static or unchanging webpages, each page is generated based on information in your database, atrepparttar 132086 timerepparttar 132087 page is accessed by a user.

Creating a web site in a language such as PHP and using a database to storerepparttar 132088 information, or some of it, has many advantages over a normal static site.

One ofrepparttar 132089 most common and most useful ways to use a database in your website is in a content management system.

What Is It And How Does It Work? --------------------------------

A content management system is a set of programs (basically, webpages containing programming code) written in a language such as PHP. The content management system displaysrepparttar 132090 content of your website to your visitors and allows you to easily add, edit or remove content fromrepparttar 132091 site without creating a new webpage.

This is accomplished by storingrepparttar 132092 content ofrepparttar 132093 site in a database. Rather than creating a "page1.html" with a layout, title, content, etc. you would storerepparttar 132094 title and content inrepparttar 132095 database, along with any other information you wanted likerepparttar 132096 author name, keywords, etc.

Then, rather than having a link to "page1.html" you'd have a URL that looked something like this:

Article.php would be a page you've written in PHP which gets information from your database. The "?id=123" passesrepparttar 132097 fact thatrepparttar 132098 user has clicked on a link to article number 123. The page would access your database, find article 123, and send back a webpage to your visitor with that article inrepparttar 132099 body. But,repparttar 132100 difference between this and a static page is that you userepparttar 132101 same webpage to access other information:

You're accessingrepparttar 132102 same article.php, but you've told it you want article 124, and a new page would be created and sent to you with article 124 inrepparttar 132103 body.
