SQL Antipatterns: Avoiding the Pitfalls of Database Programming is a useful compendium of common relation database design flaws. There are a number of anti-patterns where a single table is used to implement a data model that actually has more than one entity. Or, a metadata data model is implemented using a single table or multiple tables where, respectively, the reverse is better. The content is split into 5 parts: logical design, physical design, query, development, and appendixes. The first 3 are the most relevant to the book's title. The development chapter does have useful information on good application development practices, but could have been left out. Overall, worth reading and keeping on your self to share with others (and a reminder to yourself!) as the need arrises.
