String Operations in Query Languages
Summary: Design compositional relational calculi for string ops that avoid concatenation’s computational completeness, preserving decidability and query safety. Base language: ordering+LIKE; length checks raise bounded complexity; trim/prefix and regex extensions still admit safe algebras and low evaluation complexity.
