$3\mathrm{.}1$ Suppose you need to design a Database for a start$-$up company. The company needs to be able to track all its employee details such as names, addresses, emergency contacts, the age, race, home language, and department the employee works for. Provided you only have two departments $($IT and Sales$),$ create a mini database structure using SQL to reflect the two tables. Show any relationships that may exist between the two tables $($Employee and Department$),$ use appropriate data types for your column attributes. $(10)$

$3\mathrm{.}3$ Convert the following report into a set of $3NF$ tables. Clearly describe and show each step. You only need to provide relational schema. $(25)$
