Enter Schema & Dependencies
Schema: e.g., R(A,B,C,D), {{A,B,C,D}}, or A,B,C,D. Current Schema (after analysis): R(...).
FDs: LHS → RHS (or LHS -> RHS).
MVDs: LHS &↠; RHS (or LHS ->-> RHS).
JDs (optional): R1; R2; ... (e.g. A,B,C; C,D,E or {{A,B,C}}; {{C,D,E}}).
Separate multiple dependencies/components by semicolons or newlines. Click 'Run Analysis' to update results.
