That means they should be updatable, just as \"real\" or base tables are. In fact, view updatability isn't just desirable, it's \u003ci\u003ecrucial\u003c\/i\u003e, for practical reasons as well as theoretical ones. But view updating has always been a controversial topic. Ever since the relational model first appeared, there has been widespread skepticism as to whether (in general) view updating is even possible. \u003c\/p\u003e\u003cp\u003eIn stark contrast to this conventional wisdom, this book shows how views, just like base tables, can \u003ci\u003ealways\u003c\/i\u003e be updated (so long as the updates don't violate any integrity constraints). More generally, it shows how updating \u003ci\u003ealways\u003c\/i\u003e ought to work, regardless of whether the target is a base table or a view. The proposed scheme is 100% consistent with the relational model, but rather different from the way updating works in SQL products today. \u003c\/p\u003e\u003cp\u003eThis book can: \u003c\/p\u003e\u003cul\u003e \u003cli\u003eHelp database products improve in the future \u003c\/li\u003e\n\u003cli\u003eHelp with a \"roll your own\" implementation, absent such product improvements \u003c\/li\u003e\n\u003cli\u003eMake you aware of the crucial role of predicates and constraints \u003c\/li\u003e\n\u003cli\u003eShow you how relational products are really supposed to behave \u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eAnyone with a professional interest in the relational model, relational technology, or database systems in general can benefit from this book.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Chris J.
