Activity 1



1.1.
Identify the user and system requirements to design a database for the above scenario and design a relational database system using

conceptual design (ER Model)

by including identifiers (primary Key) of entities and cardinalities, participations of relationships.


Convert the ER Model into logical database design using relational database model including primary keys foreign keys and referential Integrities. It should contain at least five interrelated tables

. Check whether the provided logical design is normalised. If not, normalize the database by removing the anomalies.








(




Note:-It is allowed to have your own assumptions and related attributes within the scope of the case study given




)








1.2.



Design set of simple interfaces to input and output for the above scenario using Wireframe or any interface-designing tool.

Evaluate the effectiveness of the given design (ERD and Logical design) in terms of the identified user and system requirements .












Activity 2




Activity 2.1




a.


Develop a relational database system according to the ER diagram you have created (Use SQL DDL statements). Provide evidence of the use of a suitable IDE to create a simple interface to insert, update and delete data in the database. Implement proper security mechanisms in the developed database.



Evaluate the database solution developed and its effectiveness with relevant to the user and system requirements identified, system security mechanisms (EX: -User groups, access permissions) and the maintenance of the database.




Activity 2.2




a.


Explain the usage of DML with below mentioned queries by giving at least one single example per each case from the developed database. Assess the usage of the below SQL statements with the examples from the developed database to prove that the data extracted through them are meaningful and relevant to the given scenario.




Select/ Where / Update / Between / In / Group by / Order by / Having









Activity 3




Activity 3.1



Provide a suitable test plan to test the system against user and system requirements. provide relevant test cases for the database you have implemented. Assess how the selected test data can be used to improve the effectiveness of testing.





Note:- Learner needs to give expected results in a tabular format and screenshots of the actual results with the conclusion








Activity 3.2



Get independent feedback on your database solution from the non-technical users and some developers (use surveys, questioners, interviews or any other feedback collecting method) and make recommendations and suggestions for improvements in a separate conclusion/recommendations section.









Activity 4






Produce a technical documentation and a user guide for the developed database system. Suitable diagrams diagrams (Use case diagram, class diagram, flow charts, DFD level 0 and 1) should be included in the technical documentation to show data movement in the system.



Assess the developed database by suggesting future enhancements to ensure the effectiveness of the system.
