Web development is a broad term for the work involved in developing a web site for the Internet or an intranet . Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services. A more comprehensive list of tasks to which web development commonly refers, may include web engineering web design web content development client liaison client-side/server-side scripting web server and network security configuration, and e-commerce development.
Among web professionals web development usually refers to the main non-design aspects of building web sites: writing markup and coding. Most recently Web development has come to mean the creation of content management systems or CMS. These CMS can be made from scratch proprietary or open source. In broad terms the CMS acts as middleware between the database and the user through the browser. A principle benefit of a CMS is that it allows non-technical people to make changes to their web site without having technical knowledge.
For larger organizations and businesses, web development teams can consist of hundreds of people and follow standard methods like Agile methodologies
while developing websites.
Smaller organizations may only require a single permanent or contracting developer, or secondary assignment to related job positions such as a graphic designer and or information
Web development may be a collaborative effort between departments rather than the domain of a designated department. There are 3 kind of web developer specialization Front-End Developer Back-End Developer and Full Stack Developer.
Web development takes into account many security considerations, such as data entry error checking through forms, filtering output, and encryption. Malicious practices such as SQL injection can be executed by users with ill intent yet with only primitive knowledge of web development as a whole.
Scripts can be used to exploit websites by granting unauthorized access to malicious users that try to collect information such as email addresses, passwords and protected content like credit card numbers.
Some of this is dependent on the server environment on which the scripting language, such as ASP, JSP, Perl, PHP, Python or Ruby is running, and therefore is not necessarily down to the web developer themselves to maintain.
However, stringent testing of web applications before public release is encouraged to prevent such exploits from occurring. If some contact form is provided in a website it should include a captcha field in it which prevents computer programs from automatically filling forms and also mail spamming.
