1. In a computer system including a plurality of applications programs and objects for storing data, a memory and processor for storing and executing the application programs, and an integrated operating environment, a method for integrating result data from a first data object into a second data object wherein the result data is generated by operations performed on source data by an application program, comprising the steps of: creating and storing a script identifying the source data and directing the operation of the application program to generate the result data from the source data, inserting into the data of the second data object a reference to the script, the reference containing information identifying the script and the application program that is to execute the script and identifying an operation to be performed by the application program in executing the script, invoking the reference to indicate that a current version of the result data derived by operation upon a current version of the source data is to be provided to the second data object, resolving the reference to identify the script, to identify the application program that is to execute the script and to identify the operation to be performed by the application program in executing the script, invoking the application program to execute the script to generate the result data from the source data, and providing the result data to the second data object.
