Things which exist on one's personal computer are referred to as "client side", and on the web host as "server side". The average internet user might have first heard "client" in the context of applications installed on the personal computer, such as "email client". Those mail systems which can be used from anywhere are "web mail", and exist on the server side.

In practical terms, all your office suite programs, media players, programs to edit images, most games, and so forth, are probably client side, although "utility" type functions are evolving on the server side. For example, users can now share data on server side spreadsheets and word processors.

Most browser function is defined on the client side, perhaps with some JavaScript add-ons for interaction, calendars, multi-level menus, animated graphics, et cetera.

Business enterprise level content management, databases, store systems, and much more are on the server side. Server side programming can range from simple CGI scripts ("Common Gateway Interface") written in a variety of languages, such as Perl. Large databases can be built in the popular open-source MySQL, and accessed through interfaces programmed in PHP.

First embodiments of such CGI functions started a new copy of the executing module for each command request. To avoid server shutdown from excessive workload, host programmers have evolved better ways, but these need not concern us ordinary mortals.

Fortunately for this author, a web site builder does not need to be an expert in all those server side tools in order to use them. Most hosting companies now offer access to pre-installed modules. Persons wanting better features can purchase modules from third parties to upload and install, such as shopping carts, which are backed by support staff, user, or similar.

If the site builder lacks a very fast connection to the server, s/he can install client side copies of operating systems for SQL, PHP, other... to emulate behavior on the host. Sometimes the emulation is less than perfect, such as with different release generations, so adjustments may be needed after upload.

Why would anyone bother to do this? One reason is that PHP can take over parts of HTML coding, such as with "include files" which represent often used sections of header, footer, body, or serve more robustly than JavaScript for interactivity and utility functions.

If the connection is fast, however, present day "shared hosting" and "virtual private/dedicated servers" make it very difficult for one domain owner to break the system for other users. And only privileged employees have access to the power switch. VPS allows power users to get more behind the scenes than can the SH customer.

Caveat: Whether your HTML writing is done directly on host account or on personal computer for upload, keep an off-site copy against the day your hosting company drops or back levels your content. It will happen.

What ever the approach a person uses for working on the internet, all these elements are examples of "distributed processing", a concept which some large mainframe computer manufacturers had hoped would never be realized. Now that the small guys and gals have forced the issue, by using ever more powerful personal computers in place of dumb terminals, the big dogs have learned to love and profit from it.

Most web development projects include one or more of the following elements...

• Database design and creation
• Server-side computer programming
• Client-side computer programming
• Web page design

Each of these elements has to work in its own right, and in cooperation with the other elements. The more complex the project, the harder it is to bring it all together and make it work correctly.

How to keep the cost down

Here's how you can make sure your web development costs don't run over budget...

1. Insist every aspect of the development is described in an Agreement document, and make sure both you and the developer sign it
2. Don't make changes after work has started

The key to achieving the second of these two items lies with the first. You should insist that an Agreement document be created, and sit in on the process.

You need both end-users and developers in the same room, working through each aspect of the development. The end result must be a document that fully describes the development, is clear (unambiguous), and easily understood by both users and programmers.

Every minute you invest creating this document greatly increases your chance of bringing the project in on budget.

Why it's worth it

Many of the problems that usually cause headaches during a complex development could have been discovered in advance, if an Agreement document had been created. When users and programmers get together and discuss their respective needs thoroughly, the resulting development is far more likely to go smoothly.

This kind of interaction forces both users and programmers to think through what's actually required to make the system work. The ongoing interaction reduces the risk that person A assumes person B knows what they're talking about.

Users are committing to a specific set of functions for an agreed price. The developer is committing to develop those functions for an agreed price. This means both users and developers have a self-interest in being thorough.

Should a user change his/her mind about something after the Agreement document is signed, the cost of development must be renegotiated. This punishes the user for failing to think things through.

Should the developer discover he/she hasn't fully understood what's required to complete some aspect of the project, he/she can't ask for more money. This punishes the developer for failing to break down each stage of the development and understand what's involved in completing it.

Assuming you do your part, you won't need to make changes after the work has started. As a result, you'll bring the project in on budget even if the developer hasn't done his/her job properly.
