Most of the basic functionality is covered, but in a very cursory way, and with examples that aren’t contextualized or explained. SQL is introduced fairly late in the text - in chapter 15 of 16. On the whole, though, the text generally presents things in as sensible an order as is possible.

There’s a little bit of redundancy a few concepts are introduced more than once. It means that individual chapters can more easily be skipped or rearranged, but also means that readers need to internalize new examples as they’re used. The decision to not use just one or just a few running examples throughout the text is both a strength and a weakness. That said, to whatever degree modularity is possible within that structure, the text does a fine job achieving it. While not inconsistent per se, the text introduces a fair amount of terminology and notation that it then does not continue to make use of.ĭatabase Design isn’t necessarily a topic that lends itself especially well to modularity, especially when it comes to the basics, as many concepts build directly on top of each other in ways that make following a certain basic structure sort of unavoidable. The approach to exercises varies from chapter to chapter many chapters include only a single, straightforward application problem, while a few others dig a little deeper.

The focus on definitions extends to the end-of-chapter exercises, which for much of the text consist heavily of definitions problems, although some later chapters include more application. The middle section of the text is strongest, includes the best and clearest examples, and does the most to connect those examples to the text. Examples are often a bit sparse or under-explained. One of the text's weaknesses, however, is that it in many places reads like an extended glossary, providing definitions of relevant terms but often very little context for why a beginner to databases should care about those things. The text is generally written in a very accessible way - it feels like it was written for humans. (Although some methods that are still in use use the method as a foundation.) However, on the whole, I would expect the text to remain largely evergreen.

There's a few minor things - for example, the Waterfall method is of important historical interest as one of the earliest attempts to formalize the process of software design, but is no longer considered to be best practice by most people. The text generally sticks to timeless design principles, so little about the text comes off as dated. The text handles this issue as well as any, however, and doesn't delve into most of the areas where implementations differ the most. The text also has an issue that almost any general explanation of SQL has, which is that SQL implementations vary so much that it's hard to make general statements about the language. I did not notice any real errors in the text, although in some places the text gives definitions or descriptions that, while technically correct, may not be particularly useful to an introductory student due to lack of context. (For comparison, several of the most widely-used traditional textbooks are 500 or more pages.) This brevity has some advantages, but it necessarily means that the coverage of many topics is brief, high-level, and sometimes includes only minimal context.

The text is very short - just 126 pages, plus the Appendices. A course covering that material in depth would want to supplement this text. SQL is covered only briefly, and alternatives to SQL not at all.

The text is not really a guide to implementation or use, and is focused mostly on design. (For example, transactions and isolation levels are not covered.) There is also relatively little coverage of subqueries or more complex queries in general. The text is on the shorter side, so some concepts are covered only briefly, or not at all. The text covers much of the terminology I would want students to become familiar with, as well as the major concepts required for understanding database systems in the abstract. This is very much a Database Design text, not a Database Implementation text, and in those grounds is reasonably comprehensive.
