Links

One of the advantages of a relational database is the elimination of redundant information. You accomplish this by storing information about a particular subject in one place or file that has links to other subjects. Links are a combination of data and link definitions, sets of conditions containing the relationships for linked information. Use links in Incident Management and Configuration Management environments to relate information in one file to information in another.

Link records define the relationship among sets of data. They are used extensively throughout the system and the main topics include the following:

Understanding links — general linking within the system
Link maintenance — using links effectively
Virtual joins — are used to display read-only data from another file.
Posting — copy data from a source record to a target record.
