I don't know if it's right, I don't know much about physical design and logic design. Just created a table containing the ID, name, password, and level.
Create table tb_User
(
   U_id int,
   UserName varchar(100),
   Password varchar(100),
   Level varchar(100)
);

Answer 1

Logical design
=============
Defining business entities, attributes for each entity, and relationships among entities. (you can search for ER diagrams and you will understand)

Physical Design
=============
Define tables, indexes, constraints, views which will be used.
