A robust Java implementation of relational algebra (RA) interpreter for MySQL databases. The interpreter receives relational algebra queries, converts them to equivalent MySQL queries, executes them, and prints the answers. Compiler tools JFlex and JCup are used to parse RA queries. Rigorous semantic checks are enforced so that invalid queries are not executed. The system is built as a Java terminal application.

Features

  • Schema display
  • Execute query from command line or from file
