On successful completion of this module students should be able to:
Design and validate a relational database from a given enterprise description, justifying design decisions.
Implement a relational database design using a modern DBMS.
Access a relational database through an appropriate programmatic interface.
Explain and provide a rationale for relational, object, object-relational and semi-structured data model concepts.
Implement a given design in a relational system, making effective use of appropriate tools.
This module develops the concepts of database design, and implementation and use. The emphasis is on relational and semi-structured (XML) systems but object databases are introduced. It covers practical topics concerned with modelling and effective use of the facilities provided by a modern Database Management System (DBMS). Theoretical topics include data modelling, placing particular emphasis on the data model, relational algebra and the realisation of the relational model in a DBMS.
Review and persistence, outline history. The value of general models: relational; object oriented; semi-structured. Databases, DBMS and applications programs. DBMS as reuse.
2. Relational Modelling I - 6 Lectures

|Skills Type||Skills details|
|Communication||Requirements analysis is a major component. This requires careful and insightful reading and analysis of customer documents, followed by reflection of requirements back to the customer to verify mutual understanding.|
|Improving own Learning and Performance||Systematic and comprehensive analysis and design require good working practices, which are explored in the module.|
|Information Technology||Database systems are central to much IT.|
|Subject Specific Skills||Use of UML (industry standard modelling language). Use of SQL and XML languages, plus additional aspects of Java. Experience of a major DBMS.|
