Abstract: A second synthetic dataset is generated having internal consistencies with a previously generated first synthetic dataset. The synthetic data of the second dataset can be generated based on a set of rules loaded into a computer data generator for defining entities and interrelationships among events associated with the entities consistent with at least some of the rules previously used for generating the first synthetic dataset. Entities and historical information about the entities within a first observation spanning a first time period can be derived from the first synthetic dataset stored in a computer-readable memory. A second observation window can be established spanning a second time period that is different from the first time period.

Abstract: A data generation system provides for generating domain-specific, context-sensitive data collections as synthetic data for testing the performance of data processing systems. Within the data generation system, a composition module defines a data generation template containing a plurality of fields each capable of holding one or more values according to specifications defined for predetermined data types. An evaluation module sorts the fields in an order of dependency so that fields whose values affect the values in other of the fields are ordered before the fields whose values are affected by values in other fields. A data generation module populates the fields with values and retrieves a subset of the values populating the plurality of fields for generating each of a plurality of data sets, which are written into memory and made accessible for use in testing data processing systems.

Abstract: A software data interface technique allows a program to retrieve data from another program, whether or not data formats employed by the two programs are mutually compatible. An application-independent data format, Fexchange, is a priori agreed upon and readable by creators of the two programs. In the course of storing data during execution of a first program, that data file is augmented to include instructions that convert the format of the data into the application-independent intermediate data format, Fexchange. During execution of the second program, whenever access of data stored in the first program is required, the second program retrieves from the first data file instructions for converting the format of the data to the application-independent intermediate data format, Fexchange. The second program then executes the conversion instructions so as to retrieve the data from the first program.
