Making multiple tables work together

Abstract

You may wonder about the use of the word ‘object’ in this and subsequent chapters. You may have noticed heard about object-oriented programming and you might wonder if there is any connection. In fact, we are using the word ‘object’ here simply to mean ‘thing” or ‘entity’. The only reason we don’t use the word ‘thing’ is that it looks thoroughly unprofessional to do so in a book about a serious subject like databases. There is, however, no hidden complex meaning in ‘object’ as the word is used here and if you want to mentally substitute the word ‘thing’, that’s fine by me.
