Abstract: Methods and apparatus, including computer program products, for controlling projects. A logistic structure and a financial structure are specified for a project. The logistic structure includes multiple logistic objects representing activities related to the project, and the financial structure includes cost collectors representing financial responsibilities related to the project. The financial structure is independent of the logistic structure. A responsibility mapping is defined to associate each activity represented in the logistic structure with a cost collector that is responsible for financial aspects of the activity. The responsibility mapping is independent of the logistic structure representing the activities.

Abstract: Methods, apparatus, and computer program products for linking data objects. A method includes defining a first link to a first data object maintained by a first source application in a first system, defining a second link to a second data object maintained by a second source application in a second system, and accessing data from the first data object using the first link and the second data object using the second link to execute a further application.
