Unit 35 Web Applications Development Assignment Brief

Purpose of this assignment

This assignment requires you to analyse a scenario and then design, build and test a dynamic, interactive web application to meet the needs of the user. This practical demonstration of your skills will furnish you with an opportunity to utilise the latest web technologies demanded by industry.

Scenario

The largest birds of prey owners group in the UK has decided to setup a website for its members. They have agreed upon the following functional requirements:

• New users can sign up and open an account
• Existing users can sign in and out
• Existing users can add the details of a new bird in their ownership
• Existing users can query the database on the bird type (these are: eagle, falcon, hawk, owl, buzzard, harrier, kite, vulture), whereupon the name, owner, location and picture of each of the corresponding birds meeting the search criteria are display

Task 1

• List the typical features of web applications that support people who belong to a hobby and the advantages that such an application can bring to its community
• Pick two server-side scripting languages and compare them; give some example code for each. Do the same for two client-side scripting languages
• For each of the following areas, choose one security concern and discuss how it can be avoided or the risk reduced: Apache web server, SQL, PHP

Task 2

• Produce design plans for the following:
• A justification for the design of a web application to meet the needs of its users
• Logos and images
• Typography
• Storyboard for each page clearly showing the page elements
• A navigation map showing the relationship of the pages to each other and the names of the files needed to display each page
• Identify areas where accessibility could be implemented

You should produce at least two different designs and have these evaluated by a third party before deciding upon a final design to implement. You should fully document the feedback produced by the evaluator(s). A very rough ERD of the database is attached to the end of this document.

Task 3

Build the web application ensuring that your design is followed.
The application should utilise a back-end database that holds records of owners and their birds. You should employ the following technologies in your web application: HTML, CSS, PHP, MySQL and possibly JavaScript. Both kinds of scripting must be employed. You should be sure to implement some form of error handling.

Task 4

Thoroughly test your web application as follows:

• Draw up test plans and, using them, test your application to ensure that it functions correctly. The tests should be systematic and you should clearly contrast the actual results against the expected results.
• Prove that your application meets the HTML5 and CSS3 standards by submitting the files for checking online using the appropriate W3C online validator. Discuss every item of adverse feedback received and advise whether these need addressing or can be ignored. (Place the actual online W3C reports in the appendix of your assignment). Note: The validator cannot validate PHP. Instead, you need to validate the HTML code generated after it has been parsed by the PHP server. To do this, copy the source code from your browser using the view source option.
• Obtain feedback on your website by carrying out usability studies with an independent third party. Using this, list ways that your website could be improved. (note: do not implement the improvements)
• Create a short user guide to explain how to use the website you have created (sorry, but you cannot incorporate this into the website). Produce an asset list to show what files are employed, where they are located and the websites dependency upon them (build time or runtime)
