Your site can be arranged using one of several topographic models. One model can be nested inside another model in complex sites. A very complex site could connect to a database, which could have one of several different arrangements of data of its own. Databases could be contextual, relational, hierarchical, or linear. Here are a few examples of website topography:
 

The sequential model is the simplest, least flexible and looks like this:
The hub is especially good if you have one central idea and several unrelated or satellite ideas, and looks like this:
A hierarchy is most useful when a large amount of discrete data is related to more general terms or ideas:
The star can give maximum flexibility to a site, but if there are many pages, it can be confusing to the user.
The menu is the most popular model. It should have a small number of main topics. Too many choices on a single page is confusing and inefficient.
The index is helpful when large amounts of unrelated date are stored. The index model is ideal for a catalog, for example.
