Foil 17 Developing Multiuser Applications

From Overview of Microsoft Access used with Active Server Pages(ASP) CPS616 Technologies of Information Age -- Spring 1998. by Nancy McCracken and Sangetta Aggarwal


Main issue is handling errors that occur when locks are placed on pages of records. The following considerations are important:
  • Balance network security and maintenance against efficiency and speed when choosing to install Access on each workstation.
  • Balance ease of use, data integrity, and ease of programming in developing the locking strategy.
  • Awareness of errors that can occur when multiple users share data.
  • Use custom error-handling code when using bound forms with optimistic locking.
  • Use custom lock notification code when using bound forms with pessimistic locking.
  • Splitting database into separate data and application databases for increased performance.
  • Using VBA code to manage the linked tables in a split database structure.
