Abstract: Methods are for partial updating a graph's layout for nodes and their respective connections when a change to the graph occurs, each node being linked with another node by a connecting line and the connecting line being attached to the respective nodes by using a port on the node. A method of an embodiment includes receiving a user input of an update of the layout. The update includes adding a node or a connecting line, moving a node or a connecting line, or resiting a node. The method of an embodiment further includes positioning the port only on the node affected by the update and on the node connected with the affected one. The method of an embodiment further includes routing the connecting line between the affected node and the node connected.

Abstract: A system and method is provided for incremental diagram node expansion in which a table-like layout is used to place nodes. The system may include a processor configured to display a diagram through a display device that includes a pre-existing first selected node. Responsive to a first input, the processor may carry out a first incremental expansion process to add at least one outgoing level of nodes to the diagram with respect to a first selected node. The at least one outgoing level includes additional nodes that are outgoing nodes corresponding to data objects that are children and optionally grandchildren of the data object corresponding to the first selected node based on parent-child relationships stored in a data store. Responsive to a subsequent second input the processor may carry out a second incremental expansion process to add at least one incoming level of nodes to the diagram with respect to the first selected node.

Abstract: A method and related data processing system and computer readable medium. A method includes receiving, in a data processing system, a first file and a second file, and receiving comparison rules. This method includes comparing the first file and the second file, by the data processing system, according to the comparison rules, and producing an output report corresponding to the comparison.
