4. Task 1
a. Identify the database types and distinguish between a production database and a
decision-support database.

Assignment Scenario : Bus Company
A country bus company owns a number of buses. Each bus is allocated to a particular route,
although some routes have several buses. Each route passes through a number of towns. One or
more of the drivers are allocated to each stage of a route which corresponds to a journey
through some or all of the towns on a route. Some of the towns have a garage where buses are
kept. Each of the bus is identified by the registration number and can carry different numbers of
passengers. Since the vehicles vary in size , each route is identified by a route number and
information is available on the average number of passengers carried per day for each route.
Drivers have an employee no, name, address and sometimes a telephone number.
Task 2
a. Describe the different approaches available to design a database.
b. Normalize the above database up to Boyce Codd Normal Form(BCNF).
c. Show the relationship of the data identified in the above bus company using entity
relationship modeling.
d. Describe the steps of converting the above ERD to the implementation of Relational
Database.

5. Task 3
a. Using a Data Base Management System (DBMS) of your choice, create all the above
tables, and populate them with well-designed test data (minimum 5 records per table).
Provide printouts of all tables.
b. Set-up and test the following queries using a suitable visual query tool. Provide
printouts of SQL code for each query and the output
1. For each route display the total number of buses allocated.
2. Display the bus details assign for each route. that is route no, route name, bus
reference no, number of passengers carried in each bus.
3. Display the driver details working each route.
Task 4
a. Describe the main data administration functions that need to be carried out for bus the
company.
b. Examine the main activities need to be carried out by the DBAs for the administration of the
database environment.
c. Construct a security plan to ensure the security of a database and identify the main users to
the system and grant the specified database models & grant user access, security and recovery,
backup features.
