Techniques are described for sharing multidimensional data and associated annotations between software systems. As described herein, the techniques provide mechanisms for defining inter-application “links” for automatically copying data and associated annotations among databases associated with the enterprise software systems. For example, a system may include a first database storing multidimensional data for a first software application, and a second database storing multidimensional data for a second software application. The system further includes an interface by which an administrator defines a link that specifies a source area of the first database and a target area of the second database. A link control module automatically moves multidimensional data and annotations associated with cells or cubes of the multidimensional data from the source area to the target area in accordance with the link.
