Create a PL/SQL function. The minimal requirements: using the cursor in PLSQL function, retrieve data from object table and record the data in the PL/SQL table, make calculations with object data and define return value of the function, test the operation of the function (get the result). The maximal requirements: you can add IF-ELSEIF's, cursor processing in loops, more interesting semantic functions. 2. Create methods for object types. The minimal requirements: use map/order methods (1 method) (method+ demonstration), use MEMBER methods (2 methods) (methods + demonstration). The maximal requirements: non-trivial methods, that use more complex comparisons or do more complex calculations – i.e., give a couple more constructs in code. 3. Demonstrate the multiset operators. The minimal requirements: using 2 different multiset operators (can be included in the code), they can also be used in the The maximal requirements: the queries make sense semantically, one of the queries is a…
