Database Design and Development

This article discusses database design and development, including normalization, functional dependencies, and third normal form decomposition. It also includes an implementation report and bibliography. The article is relevant to students studying database design and development in any college or university.

Third Normal Form Decomposition
The solution is normalized into third normal form because there is no transitive dependency
between the table and the non key attributes are dependent on the primary key.

DATABASE DESIGN AND DEVELOPMENT
The third normal form is normalized and ER diagram is used for the demonstration of the 3 NF.
Assessor (Assessor_ID [PK] , Assessor_name, Qualification, Date_of_Qualification)
i. The primary key is Assessor_ID which identifies an Assessor name. An Assessor name
is used per Assessor ID. The other details such as thee qualification, date of qualification is
also recorded in the assessor table and there are no repetitive groups.
ii. The primary key is Assessor_ID and there are no candidate keys and thus there are no
partial dependency in the table.
iii. The Assessor Name cannot be used for determining other attribute in the table since two
different Assessors may have the same name; likewise for address and date of birth.
Therefore there are no transitive dependencies in the table. Therefore it meets the
requirements of first, second and third normal form.
Implementation Report
1. The report is prepared by combining the queries and the wizard and from the design view
the report option is selected for the development of the report from the database.

2. For the preparation of the report the tables are normalized into third normal form and the
transitive dependencies are removed for the development of the database.
