Abstract
A method and apparatus for combining undo and redo contexts in a distributed access environment is described. A first user gains access to data items residing on a database and modifies the data items. The modifications are incorporated into a user activity log. A subsequent user also accesses and modifies the same data items, which modifications are merged into the activity log. The merged activity log forms one sequential well ordered set of actions, including the modification made by the first user and the subsequent user. The user activity logs may be created for individual data items, individual users or for all modifications made to separate data items. A system for combining undo and redo contexts in a distributed access environment is also described.
