A method of validating a relationships table. The method includes generating a relational schema of symbols in the program code file based on a framework for models in the integrated development environment, the schema including two related tables. The method further includes determining a relationship between the two tables. Further, the method includes adding definitions from the program code file for symbols in the relational schema to a definition set retaining definitions of symbols. Additionally, the method includes producing proxy definitions for use with the definition set for each symbol in the program code file without a definition in the definition set. Furthermore, the method includes generating the relationships table in the relational schema containing the relationship between the two tables. Further, the method includes validating the relationships table by matching the symbols definitions and references, where the validation removes public symbols and referenced symbols from the relationships table.
