摘要
Disclosed are systems, methods, and computer programs for extracting records from a non-relational database based on one or more relational database management system (RDBMS) language statements. The system provides a user interface to a user and receives RDBMS language statements from the user, wherein the RBDMS language statements reference one or more files located in a non-relational database. The system identifies a copybook for each of the referenced files, where the copybook comprises data that defines a file layout for a respective file. The system associates the referenced files with the respective copybook, such that RDBMS selection criteria may reference data fields within the associated file. The system transforms the RDBMS language statements into commands and provides the commands and the one or more associated files to a Sort engine. The system receives a result set from the Sort engine and electronically present the result set to the user.
