3. Development

Once the project plan and functional specification are ready, a baseline is set for the development work to begin. The programmer/s or Web developer/s begin coding, testing and publishing data. This phase establishes the data variables, entities and coding procedures that will be used throughout the remainder of the project. A milestone document is prepared by the development team, which is then handed to management for review.

4. Testing, support and stability

The stability phase of the application project mainly focuses on testing and the removal of bugs, discrepancies and network issues that may otherwise cause the application to fail. It is here that policies and procedures are established for a successful support system.

Knowing Your Options and Using them Wisely Ok, now that you have an understanding of the architecture and procedures behind Web application development, let's look at what technical options you'll need to consider for the development process itself.

Windows Web Servers

Microsoft has built a loyal customer base on one important factor - their easy-to-use software. Windows NT/2000/XP Web servers are very fast and easy to administer. The fact that the operating system is a Windows shell means that administrators and authors can easily allow the Web server to interact with other software and hardware applications to transmit and receive data over the Internet. Popular server side scripting languages used with Windows servers are ASP/ASP. net, Java Server Pages, and PHP.

UNIX/Linux Web Servers

UNIX has long been known for its reliability. It is a powerful and robust Web server and operating system. Unix is the server of choice for many large-scale Websites that need content management systems or receive an extremely high volume of traffic. Popular server side scripting languages for UNIX are Java Server Pages, PERL, PHP, and CORBA

Every scripting language has its pros and cons. As I'm not writing a book here, I'll use the ASP model as my language of illustration. When working with Windows servers, there are several important parameters that the developer needs to throw into the equation, including security, scalability, speed and application design. So below I'm going to help you formulate a successful plan to accomplish all kinds of Web projects.

Planning for a Successful Web Development Project In order to drastically minimize the risk of project failure, I've always approached my application development projects in the following sequence.

1. Identify business logic and entities

Start by gathering information on everything you have. If you are going to be working with databases, begin by enumerating how many entities will be used in the business logic. For example, if your program implements sales data, a sales ticket would be an entity.
