Foil 72 Developing Multiuser Applications

From Overview of JDBC and its use with Microsoft Access UC Web Applications Certificate -- June 26 97. by Nancy McCracken(Sangetta Aggarwal, Udayan Parvate, Tom Pulikal)


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.
