Description: Joe Celko has looked deep into the code of novice SQL programmers and found a consistent and troubling pattern. These programmers have not changed their approach from writing code for a procedural language, like C, to a declarative language--which is what SQL is. As a result they are not fully using the power and capability inherent in SQL and that translates into writing more code than they need to write, more complex code than is needed, and ultimately lower productivity.
Thinking in sets reveals the conceptual shift these programmers need to make. Through detailed examples and clear explanations, Joe enables readers to concepualize database problems as rooted in sets and solvable through declarative programming techniques. The book focuses on three main table-based SQL techniques that not only demonstrate this set characteristic of SQL but also dramatically simplify application development. For each table type--auxillary, temporal and virrual--Joe teaches not only the new kind of thinking required to use them effectively but also how to choose the right table technique to apply and why.
