CGI is a unique interface that gives the user more ease in utilizing the website. Obviously, the system is also designed to make web design and development faster, less complicated, and more functional. But how does CGI do all the tasks that it could do? Let us find out what processes are involved in the CGI system and how they are crucial to creating compelling websites, and applications. Let us look at one of the simpler but more obvious applications of CGI: web forms and what happens once the user fills out and submit.
First, the user will have to fill out the form and answer all the questions. The submit button is the action that delivers all essential data to the database. The information could either be blocked, unless the form is incompletely filled or is not encoded with the right information. At this point, you are seeing the power of CGI. The information you submitted is immediately pulled by the server in a matter of seconds and is assessed by the CGI software, checking the validity or completeness of information on the form. This makes the web experience more interactive, personal and secure.
The CGI software will also prepare the information that will pass a database driver. The driver is your middleman that does the task of completing the actions or data request that the user asked from the website. The results will then pass the drivers once again, and is released using the CGI. The software will send the data and manipulate it to the format that the user expects. All of these things happen in a few seconds and thus, it makes web experience more convenient, faster and less dull. Compared to static sites, there is a lot more functionality to be derived from CGI.
In certain cases where static pages are to be made, the CGI program can also be used to access the web server’s file system, and then edit, read and write the files. The software will then send the results to the web user’s browser, so that they can get the results that they expect from the site. The CGI serves as a claw machine, but with more accuracy. It allows the user to request or pull data from the server based on the instructions or input that the individual user uses. This makes the website less tedious to create, as it focuses on database management, and manipulating data to the desires of the users.
