OSI Transaction Processing

p 1
OSI Transaction Processing (OSI TP) is an application-layer protocol
designed to link a set of cooperating programs together in a
hierarchical tree structure to accomplish a specific task and to
ensure the results of that taskare made durable, safely stored away
for the next process, by either commitment or roll back.

Isolation
  Intermediate results are not visible to unrelated operations.

Durability
  Changes are made impervious to system failure.
