The Path to Improving Database Performance Improve your indexing strategies #. 5801 Tennyson Pkwy Suite 200 Plano, Texas 75024, 15377 Memorial Drive Suite 200Houston, Texas 77079. You can easily add atomicity to this example by displaying User St Address, User City, User State, and User Zip all in separate areas. Database Design Store Binary Data Externally. However using the granularity of these low key atomic values will help keep the database more detailed and specific on what needs to be categorized where.

However having an attribute displaying atomicity is can be used in the same group but revised enough to get specific information. The proper use of foreign keys can minimize data redundancy and reduce the chance of destructive anomalies appearing. Storing âDatesâ as an INTEGER rather than as a DATE datatype will result in the incorrect number of potential values available to the attribute.
