Could you build this?
Partial A web interface for parsing and analyzing SQL is easy to construct, but building an accurate offline query optimization and diagnostic engine across five disparate database dialects without an active connection requires deep database internals expertise.
What it would actually take: The tool requires AST parsers for 5 distinct dialects (e.g., PostgreSQL, MySQL, Oracle, SQL Server, SQLite) to extract join topologies, predicate selectivity, and index candidates. The difficult challenge is modeling each engine's distinct cost-based optimizer (CBO) rules, execution plan logic, and anti-pattern heuristics entirely offline based solely on the SQL text and provided schema DDL.

Same idea, different domain
Nobody's really built a analytics & bi tool for Legal yet.
