Benefits

The benefits of a dynamic web site are quite numerous. The first and foremost benefit is that fewer web pages would need to be created. What would be created in its place would be a template that would hold specific information contained in a database. For the example mentioned above, a template would be created to hold the contents of a specific news article (such as title, date written, author, and content). The server would then call up the specific article from the database (based on previous inputs from a link or a form, etc.), and fill in the information as the Web page is being created. Instead of creating a separate web page for every article you want on your web site, you would have one template that would be used for all articles. You can this in action if you click on any of the articles shown on the example page mentions in the previous paragraph.
Another benefit is that the information on your Web site can be updated in real time. As soon as you change the information in database on the server, your web site will reflect that change immediately. Properly designed Web sites will make it easy to change the information in the database without having to download and upload the Database. An example of that behavior is shown http://www.psiphonconsulting.com/poll.cfm. When you add your opinion on what you think PsiPhòn means, you will be able to see your opinion in the survey results page.

How a Shopping Cart Works

1. Each unique user (shopper) is assigned (tagged) a unique identity code to "maintain the individualized state".

2. When a user adds an item to their cart, that item (and its attributes) are recorded and associated with that user. This can be done in 2 ways. With the first way, all the data for that item, such as quantity, options, name, description, weight, etc. are recorded (written to a text file or database) and associated to the unique identity of that user. With the second way, the item number only is associated, with that user and when that user checks out, all of the other attributes are collected, such as description, weight name, etc. The tradeoffs are between speed and memory. The first way requires more memory, and the second way takes a bit longer during checkout.

3. When the users are ready to "check out", the customer information (shipping address, phone number, payment information, etc.) is collected, and total purchase costs are calculated and charged. Shipping may be calculated on weight, number of items, total purchase price, shipping type/destination etc. Tax may be calculated on specific items, shipping destination, etc, and may or may not need to be calculated on shipping and other charges.

4. In most cases, SSL encryption is used to protect the sensitive data collected during checkout.....
