Madam is TM4ܡs primary data entry, tracking, and reporting system. A series of data entry forms provide users with an organized method of recording their experimental parameters and data. This application also serves as a repository for other tools, including a PCR scoring and microtiter plate loading utility, a study design tool, and a freeform SQL query window. Madam works closely in conjunction with a MIAME-compliant relational database to carry out its functions.
