Using ADO.NET to Develop Data Access Logic (DAL)
http://www.beansoftware.com/ASP.NET-Tutorials/ADO.NET-DAL.aspx
In the business layer you have all the domain classes with their variables, properties and methods. The variables contain the status of your business entity and are hidden to the outer world by using data hiding (private, protected). Public properties provide the data of these variables to client applications while methods implement the business logics.
It's common used to have a Facade in front of your business classes to provide communication with the client application or presentation layer. A facade combines all the methods that can be used from outside in one single class and makes it easier for others to use the business layer since it's not needed to know how everything works behind the facade.

Please note however that Veerle's CSS cannot be used for commercial purposes - to that end, I have coded two alternative CSS stylesheets - these work slightly different to Veerle's and all of the references use the #calendar absolute reference so you can copy and paste directly in your current stylesheet without worry about contamination of your other CSS styles. Both styles are included in the download zip and can be viewed here: Funky CSS Calendar and here Windows Style CSS Calendar.

Hotlinking is when another website links directly to one or more of your images or multimedia files and includes it on their web page. Not only is this theft of your intellectual property, but further more, you are paying for the bandwidth used by that site. Which can result in a problem with your budget.
The most common way to prevent others from hotlinking your content is Apache's mod_rewrite. While this a solution that free available to use, there are a couple drawbacks. One being, that Apache has to be configured to use mod_rewrite (--enable-rewrite). Another one being, that for a lot of people writing regular expressions is not the most easiest thing to do.
Of course there are commercial solutions to the problem. Probably the most common one is cPanel. An administration interface for webserver, which let's you create all the necessary items for your hotlink protection with a matter of clicks, in a matter of seconds.

Capturing click data is useful when you want to look at trends such as pages that are looked at the most, or amount of traffic.
To do this you would need to call the function below each time a page is loaded to capture the click data such as user ip, page title and url. Ofcourse you can capture more info here, for example date.
Further on you would need to save the click data in a database or text file (for example a csv file ready to be viewed in excel).

To wait or not to wait; that is the question! Whether or not to implement asynchronous processing is one of the fundamental issues that a developer must answer when invoking function calls across process boundaries. Given that the option to invoke an asynchronous call is available, the programmer has to weigh the relative ease of coding synchronous calls with its inherent drawback - when a synchronous call is made, the calling thread is blocked and has to wait until the function completes. In many instances, this is an acceptable shortcoming, as in the case when a program's logic flow should not continue until data is retrieved from a database. Asynchronous processing, on the other hand, allows more parallelism. A thread that initiates an asynchronous call is not blocked and can therefore do almost any computation while the method is in transit. The case for asynchronous processing becomes very compelling in the enterprise computing space where systems need to handle hundreds of thousands of function call requests and synchronicity may become a barrier to scalability.

Using the Parameterized Factory Pattern, we can create a VersionFactory class that returns back a version specific class based on the version type or id passed into the VersionFactory. Not only can we dynamically return a specific class, we can also move methods back and forth between the version specific classes and the VersionMain class without adjusting anything in our ASP.NET pages or outside classes. This enables us to create a default class to handle all standard versions and custom classes for those versions with special business rules while the UI section of our code is obvilious. We don't have store any information in the database stating whether it is a custom class or not. If the custom class simply exists, it is used. Otherwise, the default class is returned. The following is a graphical representation of our class diagram:
