How can a relational database management system be architected to facilitate the interactions and connections between teachers and students within a school environment, where each student may be taught by multiple teachers and each teacher may have responsibilities across different subjects and classes?

$1.$ Populate your tables with representative sample data. Ensure that at least one main table has a minimum of $25$ records. This can be a class$/$teacher$/$student$/$subject or similar table that works well with your data. Use MySQL as the platform for creating your database.

$2.$ Normalize your data as needed to at least Third Normal Form or BCNF$.$

$3.$ Create $2$ queries on your data and show the results. The queries need to be more expansive than a select $*$ from TABLE query.
