Abstract: Data cleansing of a data management system involves merging two data objects by copying one or more attribute values associated with one a source object to a target data object and reassigning any instances that refer to the source object to the target object. The source object may be deleted. A user interface is developed that allows a user to select from a list of possible source objects and target objects, view attribute values for an object, view dependent relationships as dependency trees, indicate any attribute values that should be copied and any referring objects that should be reassigned to the target instance.

Abstract: Collaborative data cleansing involves using two or more computer systems for merging two data objects by copying one or more attribute values associated with one a source object to a target data object and reassigning any instances that refer to the source object to the target object. The computer systems involved in the collaborative data cleansing exchange messages concerning the local status of the data cleansing cases.

Abstract: In inside or outside rearview mirrors of motor vehicles, the mirror housing (2) and the frame (4) constitute two parts, whereby the frame (4) is held on the mirror housing (3) by means of clips. In order to produce the component (2, 4) in a simple and economical manner, the two components are joined to each other by laser welding with their faces flush and contiguous. During the process, a laser beam is directed onto the contiguous edges and along the corresponding part such that the edges are welded together. The laser beam can also be directed by a third part, which reflects the laser beam to the flush, contiguous edges of the two other parts (2, 4), along which it is moved. The component (2, 4) and the method are preferably used to manufacture inside or outside rearview mirrors of motor vehicles.
