Assignment Brief:
Some of the most difficult decisions that you face as a database developer are what tables to
create and what columns to place in each table, as well as how to relate the tables that you
create. Normalization is the process of applying a series of rules to ensure that your database
achieves optimal structure. Normal forms are a progression of these rules. Each successive
normal form achieves a better database design than the previous form did. Based on your
understanding for the various normal form respond to the following problems and provide the
optimal answer/solution.
Problem#1: 1st Normal Form (1NF)

Which of the following is a key part of physical design in an entity
relationship model?
O This model converts attributes into columns.
O
This model does not depend on the database management software or
the hardware used to implement the model.
O This model avoids any database model-specific details.
This model resolves the many-to-many relationships to multiple one-to-
many relationships.
8.When constructing a database, the designer mustknow what types of relationships exist betweenrecords in different data sets, such as one-to-many or many-to-many. Give three examplesfor each of these relationships.

Each employee has a unique employee id, and can join in projects that in different department. DEPARTMENT (DNO, Dname, Manager_id, Dlocation). The attribute means: Department number, department name, department manager id, department location. The department manager is a type of the employee, thus the Manager_id is a foreign key that references the Employee_id in EMPLOYEE table. PROJECT (Project_NO, Pname, DNO). The attribute means: project number, project name, department number of the department that the project belongs to.
