Most writers are somewhat familiar with at least one or two database programs that run on personal computers, such as Microsoft’s Access or Filemaker or Borland’s Paradox. PC database programs differ from the programs used to organize the large online databases in ways one might expect. They are designed to handle smaller collections of information for more specific needs. There are several different types of PC database programs: standard (or structured), unstructured, and bibliographic database programs, which are a kind of hybrid between structured and unstructured database programs.
