Calwa web development and Calwa web design specializes in, or is specifically engaged in, the development of World Wide Web applications, or distributed network applications that are run over HTTP from a web server to a web browser.
Web development in Calwa is a broad term for the work involved in developing a web site for the Internet (World Wide Web) or an intranet (a private network). 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 design, web content development, client liaison, client-side/server-side scripting, web server and network security configuration, and e-commerce development. Among Calwa web professionals, “web development” usually refers to the main non-design aspects of building web sites: writing markup and coding. Most recently Calwa web development has come to mean the creation of content management systems or CMS. These CMS can be made from scratch, proprietary (such as OpenText), or open source (such as Drupal). 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.
Web developers in Calwa are found working in all types of organizations, including large corporations and governments, small and medium – sized companies, or alone as freelancers. Some web developers work for one organization as a permanent full-time employee, while others may work as independent consultants, or as contractors for an employment agency. Calwa web developers typically handle both server-side and front-end logic. This usually involves implementing all the visual elements that users see and use in the web application, as well as all the web services and APIs that are necessary to power the front-end.
Web applications undergo the same unit, integration and system testing as traditional desktop applications. But because Calwa web application clients vary so greatly, teams might perform some additional testing.
For larger organizations and businesses, Calwa web development teams can consist of hundreds of people (web developers) 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 systems technician. Web development may be a collaborative effort between departments rather than the domain of a designated department.
Since the commercialization of the web, Calwa web development has been a growing industry. The growth of this industry is being pushed especially by businesses wishing to sell products and services to online customers.
Just as with a traditional desktop application, web applications have varying levels of risk. A personal home page is much less risky than, for example, a stock trading web site. For some projects security, software bugs, etc. are major issues. If time to market, or technical complexity is a concern, documentation, test planning, change control, requirements analysis, architectural description and formal design and construction practices can mitigate risk.
For tools and platforms, the public can use many open source systems to aid in web development. A popular example, the LAMP (Linux, Apache, MySQL, PHP) stack is available for download online free of charge. This has kept the cost of learning web development to a minimum. Another contributing factor to the growth of the industry has been the rise of easy-to-use WYSIWYG web-development software, most prominently Adobe Dreamweaver, WebDev. Using such software, virtually anyone can relatively quickly learn to develop a very basic web page. Knowledge of HyperText Markup Language (HTML) or of programming languages is still required to use such software, but the basics can be learned and implemented quickly with the help of help files, technical books, internet tutorials, or face-to-face training.
Dealing with web developing projects requires those who wish to be referred to as web developers to have advanced knowledge/skills in:
server/client side architecture
Programming/Coding/Scripting in one of the many server-side frameworks (at least one of: Perl, Python, Ruby, PHP, Go, CFML – ColdFusion, Java, ASP, ASP.NET)
Ability to utilize a database
An ever growing set of tools and technologies have helped Calwa web developers build more dynamic and interactive websites. Further, Calwa web developers now help to deliver applications as web services which were traditionally only available as applications on a desk-based computer. This has allowed for many opportunities to decentralize information and media distribution. Examples can be seen with the rise of cloud services such as Dropbox, Adobe Creative Cloud and Microsoft’s Office 365. These web services allow users to interact with applications from many locations, instead of being tied to a specific workstation for their application environment.
Examples of dramatic transformation in communication and commerce led by Calwa web development include e-commerce. Online auction-sites such as eBay have changed the way consumers find and purchase goods and services. Online retailers such as Amazon.com and Buy.com (among many others) have transformed the shopping and bargain-hunting experience for many consumers. Another good example of transformative communication led by web development is the blog. Web applications such as Calwa WordPress development and Movable Type have created easily implemented blog-environments for individual web sites. The popularity of open-source content management systems such as Joomla!, Drupal, XOOPS, and TYPO3 and enterprise content management systems such as Alfresco and eXo Platform have extended web development’s impact at online interaction and communication.
Calwa web development has also impacted personal networking and marketing. Calwa websites are no longer simply tools for work or for commerce, but serve more broadly for communication and social networking. Websites such as Facebook and Twitter provide users with a platform to communicate and organizations with a more personal and interactive way to engage the public.
