Resubmit Chapter 3 & 4

Already submitted chapter 3 and 4 after done few corrections from the previous comments.

Comments:-

Chapter 3:

• Don't have to explain each of the methodology studied. Only give the comparison between methodologies and brief more about the one that chosen to be used for the portal development.
• Then, explain each of the phases in the methodology chosen. Few other contents in chapter 3 need to be removed as it needs to be done during PSM 2.
  
• Rewrite needed.

Chapter 4:

• Rewrite needed since some of the headings are incorrect. No more further checking by miss as I need to resubmit it again with the proper format.
  
• Interface designs was okay. Don't place the "Sign Up" at the bottom of the page, if on top of the page is better.
• Some of the content needs to be removed such as testing as it will be done in PSM 2.
