Here is some information about SENECA MECHANICAL LAB:
SENECA MECHANICAL LAB provides tools to students studying in the mechanical
engineering department. You are asked to design an Inventory Management System for
the lab to keep track of the inventory on hand and to track the use of items by students.
Students can login on with their valid credentials and search for the items they want
to rent, The administrator and lab technicians are provided with the additional
views in which they are allowed to issue an item to the student and to add, modify or
delete the entities in the system.
Inventory management module contains all the features like add, modify and delete
an item, along with item search based on any criteria. The system should also
facilitate the purchase orders; the administrator, lab technician or faculty is allowed
to place the orders from the inventory system by a secure login. The placed orders
can be viewed in the order search page, along with the order status.
Note there is a One-to –Many relationship between STUDENT and ITEM. One student
can borrow more than one item.
The weekly usage report can be printed for all items, which shows the
items borrowed by students during last week.

 For all questions from Part 2 to 8 perform the SQL commands on a group member’s

seven tables defined above. Column names must be the same as those shown in the data
dictionary. Use proper formatting(indenting). Secure the collection so the public does not
have access. Allow schema access to Your Instructor (that will be explained in your
class) and the profiles in the group.
Part 3: Hand-in the Insert statements used to insert three Rows for each Table
 You should use data from the two reports and you may also need to invent some
data.
