Lecture Notes in Computer Science not necessarily the most useful one. Often a table or spreadsheet is designed to mimic a possible data entry screen or a hoped—for report. This practice may be adequate for solving the immediate problem (e.g., storing the data somewhere); however, mimicking a data entry screen or report in your des

By looking carefully at the details of the model, we were able to develop questions to help understand further subtleties and complexities of the real-world problem. We then looked at a number of situations that occur in many models in the hope that these would be usefu

M. N. Çağatay,N. Görür,B. Alpar relationships between classes with primary and foreign keys and then applied the ideas of normalization to ensure the attributes were in the right tables. In this chapter, we take another look at some of these ideas and think about some alternative possibilities. In particular, we take a closer loo

The data will be stored in many separate tables, and depending on the questions we are asking, we will need to combine data from those tables in a number of different ways. This chapter is just a brief introduction to the

Catastrophe Theory and Ecology, and the interrelation of the different data items. Chapters 7 through 9 showed how we could take the data model and represent it in a relational database as a set of normalized tables with the relationships implemented by foreign keys. The previous two chapters showed how we could efficiently enter
