The work that is done to develop a website for internet or intranet is called web development. This includes design, content development, client liaison, web server, client side scripting, network security configuration, eCommerce development and server side scripting. But generally it is writing markup language and coding. This usually ranges from a simple single page web site to the most complicated applications like electronic businesses or social networking sites.
This process involves hundreds of people in larger organizations whereas in smaller organization one good web master may do the work. There is a need of a graphic designer and an information systems technician for assisting. This is actually a collective effort of various departments and is not confined to a single department.
Web development – an industry
Web development is a fast growing industry the reason for which may be attributed to the large businesses which try to sell their products and services by automating their business. In addition to this the cost of developing and hosting a website has decreased to a large extent. There are free website builders like Google sites which made easy to develop a website so easy now a days. Online auction sites and online selling sites have changed the shopping style of customers. This has led to another level of internet communication. There are web sites which provide the users a means to communicate easily.
Areas of Web Development:
This may consist of many areas but the basic hierarchy may be seen as follows:
Client side coding: This is basically the look of the web site. The part of the website that is available for the client which can be refreshed by the server side data which is not available for the client. Even if they change the local content of the site there will not be any effect on the server side content which is taken care of by the web designers.
Server side coding: This actually takes care of the presentation of the site with the help of the server and is dynamic in nature. This actually involves systems analysis and design, software engineering, hypermedia/hypertext engineering, human-computer interaction, user interface, information engineering, information indexing and retrieval, testing, project management, and graphic design and presentation.
Client side + Server side: This involves the usage of high level languages which take care of both front end and database applications.
Practical Web Development
The web developers usually start their work with web design, information architecture, copy writing, usability, accessibility and search engine optimization as the main driving forces. This can be suitable for a simple web site development. For an advanced web site the developer may consider many other aspects which include graphic user interface design, flash capabilities, content management system, web server stress testing, security analysis and testing, code optimization, project management, quality analysis and other aspects which usually arise in IT development.
Data entry error checking, filtering output and encryption are some of the features that web developers incorporate in their web sites. It is very important to disallow the users to access secure information like credit card numbers, passwords etc. This calls for a strict testing of the web applications before they are launched though the security is dependent on the server environment.
Securing a web server from any type of intrusion is termed as Server Port Hardening. Now-a-days there are many technologies which help to keep the information on the internet secure during its transmission from one location to other. Secure Socket Layer certificates are an example of such technologies which helps in preventing any hacking. A web developer needs to have a basic knowledge about these security issues.
Though the web site is tested before launch there may be some loop holes which need to be sealed. Hence a web developer should always keep the updated version which has sealed holes to prevent security issues.
