If a query is executed that asks for all rows with a value greater than 100 for that column, the optimizer will know without even looking at the data that no rows meet the criteria. Regardless of whether constraints help query performance directly, their part in maintaining data quality is one of the biggest factors in overall system performance. Beyond the topics I covered on normalization and datatypes, consider a database that contains the calendar of speakers for an event. Suppose that the database is perfectly designed but a few speaker assignments are not right.
Like in many cases we have discussed so far, the goal of this rule is to get the design right so that you don’t have to mess around with poorly formatted data. When the keys that you expect to represent a single value actually represent multiple values, your data gets messy and dealing with bad data is the single largest cause of poor performance on many levels. Of course, sometimes the performance issues arise only after you discover that your data is massively messed up and you have layered on tons of hacks to keep it in order.
Note that initially it seems like you have more data because you have more rows and more tables. However, notice the redundancy in the following data from the original design: Louis Chuck Normalization Normalization DB Design & Implementation DB Design & Implementation The redundancy comes from stating twice that the book DB Design & Implementation is used for the Normalization class. The new design conveys that same information with one less row of data. When the system grows to the point of having 50 Normalization classes being taught, you will have much less data, making the storage of data more efficient, possibly creating some performance benefits, and reducing the amount of redundant data that can get out of sync.
