How Programmers write Software to Support Your Company's Business Systems

Non-programmers are shocked to find out how many different types of software are involved in producing an interactive web site.

First of all there is the software operating on the Web Server. You can think of this as the main program that contains all the processing steps needed to produce the results. I use PERL - a scripting language that operates on the Web Server to generate web pages in html for your browser to see. You click on an option shown on your screen and PERL takes that piece of data and follows a series of steps to process it.
Secondly there is the database program itself that sits on the Web Server. Most use SQL - Structured Query Language for the engine to run the database program. It tells the database to store, retrieve and manipulate the data to produce a result. I primarily us MySQL as the database program of choice due to its speed.
Thirdly, you must have a program that will interface between the main program and the database. The most commonly used one is DBI or Database Interface. This program operates between PERL and MySQL to connect the two programs.
Fourthly, there is HTML. Not a programming language in the strict sense, but rather a markup language that tells your browser how to display the data. Your programmer and web-designer are both required to have a though understanding of HTML or you won't be able to see it.
Finally, there is Java Script. Java Script applets operate on your local computer and give the programmer the ability to do limited data checking and manipulation without calling the Web Server programs. This is a big time saver for checking such things like 'is there a legal date of February 31?'

These are the basics for any competent web programmer. There are other exotic programs available that can be used, each with there strengths and weaknesses. As a CPA, I was used to producing highly technical tax returns in a manner of hours or maybe a few days. As a programmer, I have to think in weeks and months to complete a project.
