Site structures:

Hierarchy- Much like how you divide a book into chapters into sections into paragraphs into sentences into words into letters. New websites are encouraged to use a broad and shallow hierarchy technique so it can easily be added on to. If the main place has more than 10 options it may be hard for viewers to find what they are looking for.

Hypertext- is a non-linear structure. Hyperlinks connect page to page. The hyperlinks can be text, data, image, video, and audio chunks. This kind of site can confuse viewers because it may be hard to retrace your steps to find a certain page. If you pair this hypertext model with the hierarchy model it may be easier to navigate.

Database- This is where you search for specific data by typing in a keyword tagged to that data. This model is best for catalogs and archives with lots of information.

Sequences- Just a straight line of pages. Good if you have a four or five page article. Not a very good layout for a website with multiple purposes or a site with lots of content. Linear sequences may have pages of supporting digression that come off of the main sequence.

Webs- Each page has several links that go to the other pages; giving the viewer a free flow of ideas. All though these pages allow users to follow their interest they can be confusing and easy to get lost in.
