Visual –spatial model
- Planning- to conceptual Site definition and planning
- Content- known as Information architecture (researching, writing and adapting content for individual web pages, including markup and scripting)
- Structure- Developing the overall structure, arrangement of pages and navigation tools. (site construction)
- Design- Designing the visual content, page layouts and interface elements
- Usability- Formal comprehensive testing of the site for usability and accessibility prior to publishing the site. (Tracking, evaluation, and maintenance)
Basic usability principles in Web environment
From my google, searching, I found that there are basic usability web design principles that includes:
(1) navigation
(2) response time
(3) credibility
(4) content.
And this suggests:
· easy-to-use navigation
· frequent updating
· minimal download times
· relevance to users, and
· high-quality content that also takes advantage of capabilities unique to the online medium (Nielsen 1993)
Shackel's Acceptability Paradigm model
Shackel’s acceptability paradigm model illustrates four things (usability, likability, utility and speed) and the balance between those aspects and the user’s financial and social costs. When users make a decision about using a web site, they weigh:
· how useful it will be (usability)
· its perceived ease of use (utility)
· its suitability to the task (likability) which relatively affected
· speed (response time) of web page, and
· how much it will cost them (Cost)
To satisfy customers, a Web site must fulfill four distinct needs:
- Availability: A site that's unreachable, for any reason, is useless.
- Responsiveness: Having reached the site, pages that download slowly are likely to drive customers to try an alternate site.
- Clarity: If the site is sufficiently responsive to keep the customer's attention, other design qualities come into play. It must be simple and natural to use – easy to learn, predictable, and consistent.
- Utility: Last comes utility -- does the site actually deliver the information or service the customer was looking for in the first place?
Visibility Analysis Model
· How do users' eyes move across a web page?
· How much attention is paid to the different regions?
· Is attention directed to the relevant elements?
Web Development is used to bring interactivity into the website. Interactivity or dynamicity helps in making more of the visitors experience over searching the things from website.
Web Development refers to the non-design aspects of building web sites.
Website Development includes writing server side scripting codes in different languages and usage of database. There are different types of server side scripting languages and databases.
Server Side Scripting Languages
- ASP.net
- ASP (Active Server Pages)
- PHP (Hyper Pre Processor)
- VB.net
- Drupal
- ColdFusion
- CGI and/or Perl
- C Server Scripts
- Groovy (programming language) Grails (framework)
- Java
- Lotus Domino
- Python
- Ruby
- Websphere (IBM proprietary)
- Zoomla Templates
Database
