To provide an in depth understanding of the database design process, and a range of implementation issues including transactions and recovery, query processing, distributed DBMSs and security.
• Database design methodologies;conceptual, logical and physical design; conceptual database design methodology;use of ER modelling to build a conceptual data model.
• Deriving a set of relations from a conceptual model; validation using normalization techniques; validation with respect to transactions;merging local data models to obtain a global model.
• Mapping a logical design to a physical design; designing base relations for a target DBMS; designing general constraints; selecting file organizations for transaction processing; using indexes; designing user views; security mechanisms.
• The need for database security; Types of threats; Mitigation techniques; MySQL grant tables; Understand how a firewall can protect a database in a web based environment.
• Properties of transactions; concurrency control; database backup and recovery; the database administrator role. Understand professional issues and responsibilities (e,g, backup)
• Query processing; query decomposition; query optimization; the cost of queries.
• Introduction to distributed DBMSs and their architecture; data allocation and fragmentation; transparencies; data replication.

Equivalent to 40%. Uses key areas of theory or knowledge to meet the Learning Outcomes of the module. Is able to formulate an appropriate solution to accurately solve tasks and questions. Can identify individual aspects, but lacks an awareness of links between them and the wider contexts. Outputs can be understood, but lack structure and/or coherence.
Equivalent to the range 60%-69%. Is able to analyse a task or problem to decide which aspects of theory and knowledge to apply. Solutions are of a workable quality, demonstrating understanding of underlying principles. Major themes can be linked appropriately but may not be able to extend this to individual aspects. Outputs are readily understood, with an appropriate structure but may lack sophistication.
Equivalent to the range 70%+. Assemble critically evaluated, relevent areas of knowledge and theory to constuct professional-level solutions to tasks and questions presented. Is able to cross-link themes and aspects to draw considered conclusions. Presents outputs in a cohesive, accurate, and efficient manner.
