Developing a Relational Database System, Cheat Sheet of Law

A comprehensive overview of the process of developing a relational database system. It covers the key steps involved, including creating the database, designing and implementing tables with appropriate primary keys, foreign keys, and data validations, performing crud (create, read, update, delete) operations, and querying data across multiple tables using various sql clauses. The document also outlines the assessment criteria for different performance levels (pass, merit, distinction) and the corresponding requirements, such as implementing a query language, testing the system, and producing technical and user documentation. Likely to be useful for students studying database management, software engineering, or information systems, as it covers both the practical and theoretical aspects of database development.

M2 Implement a fully functional database system which includes system security and database
maintenance.
M3 Assess whether meaningful data has been extracted through the use of query tools to produce
appropriate management information.
M4 Assess the effectiveness of the testing, including an explanation of the choice of test data used.
M5 Produce technical and user documentation for a fully functional system, including ER Diagram and
normalization statements and describing how the system works.

D2 Evaluate the effectiveness of the database solution in relation to user and system requirements, and
suggest improvements.
D3 Assess any future improvements that may be required to ensure the continued effectiveness of the
database system.
