The present disclosure describes methods, systems, and computer program products for generating data for performance evaluation. One computer-implemented method includes identifying a source dataset from a source database, extracting a schema defining the source database, analyzing data within the source dataset to generate a value model, the value model describing features of data in each column of each table of the source dataset, analyzing data within the source database to determine data dependency, and generating a data specification file combining the extracted schema, the value model, and the data dependencies.
