Parsing of DDL files will be done with ANTLR grammars for different dialects. Writing of grammar rules is precise process and it need constant feedback of how rules work. Control sets of DDL files for different SQL dialects will ensure the feedback on every stage of grammar development.
Internet can be good source of DDL files with correct syntax, so this sub-task will involve series of searches over the network. Control set also will be used as resources for JUnit testing of the grammars.
