This course was taught to second-year undergraduates on the University of York Computer Science Department's main computing B.Sc. degrees. I taught it six times between 1990 and 1994. It would need considerable updating before it could be used again.
- Student weekly workload
Weeks 1-9: 2 * 50 min lectures, 4 hrs private study
To tackle this course, students need to know:
- some discrete maths: set theory, relations
- some procedural programming, including file handling
Unseen half-paper (1.5 hrs): one short answer question (choosing 7 out of 10 parts, worth 10 marks), and choosing 2 from 4 long questions (each worth 20 marks).
Every information system needs some form of data repository. The advantages of using database technology to provide this repository in computerised information systems have long been recognised. Databases can now be found in information systems for application areas as diverse as business data processing, scientific data analysis and engineering project support.
This course investigates the concepts common to the use of databases in all these areas. Roughly equal weight is given to database technology, to database theory and to the process of database design.
- Students should become proficient in designing database systems for business applications.
- Students should become proficient in using and writing programs for interrogating commercial relational database technology.
