Abstract: A system and method of extracting information from electronic data sources that includes generating a list of file names containing the information to be extracted. Each file name in the list is read into memory, the file that corresponds to the file name is read into memory, and the information is extracted from the file by executing a series of programming instructions. The information is saved to an extracted file, and one or more file names in the list is identified to correspond to an extracted file.

Abstract: Configurations of client specific taxable transactions are validated by inputting client initial transaction data to a test deck generating program which is executed to generate a client tax configuration test deck comprising the initial transaction data, assumed transaction data, and expected taxability of the initial transaction data and assumed transaction data. A tax determination program is executed using data from the client tax configuration test deck to generate simulated tax calculations. The simulated tax calculations are input to a configuration validation program to compare the simulated tax calculations with the expected taxability of the transaction data to identify defects. A report is generated identifying any defects.
