Organiser: Mr Andy Harbach

Overall aims and purpose

To provide an in depth understanding of the database design process, and a range of implementation issues including transactions and recovery, data storage techniques, query processing, distributed DBMSs and security.

Course content

• 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; transactions, concurrency control, database recovery and query optimization in distributed systems; data replication.

Learning outcomes mapped to assessment criteria







Understand and apply a conceptual database design methodology

Can distinguish conceptual, logical and physical designs. Can read and understand a simple ER model. Can design a conceptual model for a limited scenario involving a small number of entities. Can design a conceptual model for a realistic scenario involving a substantial number of entities.

Understand and apply a logical database design methodology for the relational model.

Can describe in outline how a set of normalised relations can be derived from a conceptual model Can design a logical model for a realistic scenario involving a substantial number of entities. Can design a logical model for a limited scenario involving a small number of entities.

Understand and apply a physical database design methodology for a relational database.

Can understand the basic differences between the different types of storage/organization techniques. Can fully explain the details of all the storage techniques and discuss their applicability. Can distinguish the appropriate type of storage/organization for a set of requirements.

Understand database security issues.

Can describe a range of common threats to a database system. Can provide basic mitigation against security threats. Can provide comprehensive mitigation against security threats and understand a DMZ.

Understand transaction and recovery issues.

Can test transactions for serialiability; can apply concurrency control techniques to non trivial transactions. Can explain the fundamentals of transactions and why concurrency control mechanisms are needed. Can explain the concurrency control techniques; can understand how a transaction log is used in database recovery

Understand the basic concepts of Distributed DBMSs

Understands in broad terms the problems associated with a distributed database. Understands in depth distributed concurrency control and distributed database recovery Given a set of user requirements can determine the optimum distributed database design and design any necessary optimized distributed queries.
