Links To Tables. Access links are used to import your original data for standardization and linkage. An Access link is a pointer from an Access database to a data table which is not necessarily another Access table. Your original data should not be changed in any way by linking and copying. By default, a new Access link has the same name as the external table. You must change the name of the link if it conflicts with any name used for your data source (for example, Crash__In or Crash). The latter links are created by the system and will overwrite your earlier links.
