| 摘要 |
An integrated data processing system including an application program that has means for generating and editing data files, each data file including an array of data objects that each have an associated object address, and object content being any of a number, a formula, a date, a text, media data, and binary data other than a number, a formula, a date, or a text, each object address in a data file being unique with respect to that data file. The means for editing includes means for selecting a source subset of the data objects of the data file, the object addresses thereof being source object addresses, means for copying the source subset as target data objects to different object addresses, means for selectively linking the target data objects to their corresponding source object addresses, means for modifying values and/or addresses of the source subset as reflective of further editing of the data file, and means for maintaining the linkages between the target data objects and the source object addresses following modification of the source object addresses.
