O*NET, the Occupational Information Network, the nation's primary source of occupational information, has a vast web site that contains a massive database containing information of standardized and occupation-specific descriptors. 

The database contains information about knowledge, skills, abilities, interests, general work activities, and work context. The user can also find occupations to explore, search for occupations that match specific skills, view occupational summaries, and much more. 

A detailed navigation system aids the user in choosing the portals that will best suit their needs when visiting the site.
