Systèmes de traitement de l'information — Interconnexion de systèmes ouverts — Transfert, accès et gestion de fichiers — Partie 3: Définition du service de fichiers — Amendement 2: Chevauchement d'accès

Extends the service definition of the externally visible file transfer, access and management service given in ISO 8571 part 3 in an abstract way to incorporate the services offered by overlapped access. The objective in introducing overlapped access is to allow more efficient access to structured files when a single initiator has a need to perform many reading and updating operations.
