XYZ Company is a car Production Company. It has four factories and
many distribution outlets spread across the country. The company keeps
online records of the sales of its cars. It also creates batched
production schedules on the basis of the sales of the car. The car
production is done at a nearest factory so that the cost of transfer
of cars to distribution center is minimized. Each factory also
maintains its inventory. The company maintains a distributed database
management system keeping all the above information. The following
information may be stored in the Distribution and Inventory management
system of the company: (Please note that the following description may
lead to un-normalized relations, normalize them wherever required. You
may also add more tables as per your analysis)
Data Store Name Description
Distribution outlets It includes outlet code, outlet name, outlet
address, list of car models, sales made for each model etc.
Factory It may be keeping information about each car inventory items
(Model Wise). It includes item code, item name, model in which this
item is used in a single Car unit, and quantity in stock, time taken
to produce a batch of 100 corset. This information is stored factory
wise. Each factory will have separate minimum stock and reorder level
based on its capacity.
Batched order It includes details on overall sales of cars at various
outlets; all such sales are put together to generate a consolidated
order for factories. On the basis of such orders the factories make
cars.

Assume that only following two applications exists:

a) Keeping track of status of inventory so that the delays in
production of cars can be minimized. Proper reorder level should be
kept so that a given order of cars is completed with full assembly
load in desired time.

b) It evaluates the performance of each distribution outlet of the
company. Design a distributed database assuming that at present the
company has only 10 outlets. Also assume statistics, which justifies
your design.

Your design should include:

I. The global schema, fragmentation schema and allocation schema.
II. SQL commands / application code for above queries / applications.
III. How the response for application 1 and 2 will be generated?
Assuming these are global queries, explain how various fragments will
be combined to generate the query response.
IV. Implement the database at least using a centralized database
management system (make suitable adjustments in your design)
