Higher Information Systems

The Higher Course Comprises 2 core units, Relational Database Systems and Using Information, and one optional unit, with Expert Systems being the unit of choice in the department.

A vital component of the course is the coursework task, which comprises 30% of the overall mark for the course. The coursework is in 2 parts. Part 1 considers Relational Database Systems and involves the creation of a relational database with the establishment of relationships, data validation and implementing reports. Initially, pupils will be asked to create one part of a data dictionary.

Databases Considering databases at Higher level is unlike anything pupils will have encountered previously in their dealings with this ever so important tool in the blah. Considering anomalies, normalising from Un-Normalised Form (UNF) toThird Normal Form (3NF), creating data dictionaries, implementing solutions and creating queries, forms and reports are only some of the issues to be considered in this core topic. Assessment is undertaken via a multiple choice National Assessment Bank (NAB) with the practical aprt of the NAB undertaken during day to day practical tasks in class.
