RelConverter
PeerComp is my course project for CMPS 277 in Fall 2009. It was a graduate level database system course, mainly covered database theories, Datalog and complexities.
RelConverter is a tool of converting relational algebra to relational calculus and SQL, writen in Python. It uses PLY as lexer and parser. RelConverter also allows user to easily add new translator by employing attribute information. For more information, read README in the archive.
