An exciting new book for all students taking the Higher Information Systems course, focusing on two core units - Database Systems and Using Information. Database Systems explores the fundamentals of relational database systems and their analysis, design, implementation and evaluation. Techniques for describing database structures and the requirements of good database design are discussed fully. Using Information is looked at in terms of the need for information, the characteristics of information used for business processes, and the way planning, control and decision-making are used within organisations. The use of computer applications for information processing and the social, ethical, and legal implications of Information Systems are considered in detail. Questions are interspersed throughout the text to engage students and to ensure that they have understood the content covered.
