DATA MODELING AND ANALYTICS

Part A: Conceptual Data Model

Students are expected to develop a Conceptual Data Model (CDM):

1. Research the system. This should include a description of the business, along with its major functions or a description of the business scenario if relevant.

2. Create a Conceptual Data Model identifying the entity types and the degree of the relationship.

3. The data model should include different types of relationships/associations (e.g. 1..1, 1..M, M..M) and at least one type of supertypes/subtype relationship.

4. Explain the assumptions/decisions/ business rules underlying the CDM.

Part B: Logical Data Model

1. Review the design of the LDM, modifying the CDM if considered necessary.
2. Select primary and foreign keys.
3. Identify attributes for your entity types.
4. Identify data types.
5. Establish rules.
6. Engage in normalisation (3NF sufficient).

Part C: Database Design

1. In this component, the student is expected to use all the documentation above to implement the actual database in the MySQL environment.

2. Review the design of the Physical Database Models modifying the CDM/LDM if considered necessary.

3. Create and test the Database code including a sufficient number of insert statements to validate each table (entity type).

4. Submit at least two scripts: one that creates the database, users and tables as well as populate the database. Another script that contains the list of frequently used queries for that database. The Student should provide an explanation for the frequently used queries as well as problems encountered.
