Optimizing the Organization Database of a Workflow Management System

1 Introduction

   Workflow management, as for example implemented by MQSeries Workflow , involves the three dimensions as shown in figure 1.

   The first dimension, the process logic dimension describes the actions to be performed, by whom they have to be performed, with which program they have to be performed, and in which sequence they have to be performed.

   The second dimension describes the organizational structure, the people, the roles the people are playing, and the server the people are assigned to.

   The third dimension describes the IT infrastructure, such as the workflow servers, and the workstations/programs used by the users.

   The actual execution of a workflow is then a series of points in the three-dimensional workflow space. Each point represents the execution of an activity by one person at one computer using a particular program.

   When the workflow management system reaches an activity during navigation through a process graph, it performs staff resolution for the staff assignment associated with the activity. This staff resolution results in a set of persons, that will be assigned to perform the task. This assignment is indicated to each of the selected persons by assigning a workitem to them. When a user selects a workitem, the task is assigned to the user and the appropriate activity implementation is invoked.

   A staff assignment is specified as a query against the organizational database. Staff resolution carries out this query which returns the qualified people. The efficiency of this query depends on the physcial scheme of the organization database. This software patent proposal outlines a method how an optimal physical scheme for the organizatio...
