A memory management architecture in a testing environment including a memory cache and a hard drive is provided. The hard drive may be configured to receive a high-volume set of production data including computer-readable spreadsheet files in varied file formats. The memory cache comprised in the memory management architecture may be configured to receive and store from the hard drive a first subset of the high-volume set of production data. This form of retrieval allows for not having to receive from off-site or from an external source. The memory management architecture may also include a diagnostic tool that may be used for data analysis. The diagnostic tool may analyze and test the fields listed on the field list, for any errors and/or omissions. When the data analysis and testing is complete, the diagnostic tool may then generate a data analysis summary report based on the analysis.
