A Practical Guide to Database Design

Fully updated and expanded from the previous edition, A Practical Guide to Database Design, Second Edition is intended for those involved in the design or development of a database system or application. It begins by illustrating how to develop a Third Normal Form data model where data is placed “where it belongs”. The reader is taken step-by-step through the Normalization process, first using a simple then a more complex set of data requirements. Next, usage analysis for each Logical Data Model is reviewed and a Physical Data Model is produced that will satisfy user performance requirements. Finally, each Physical Data Model is used as input to create databases using both Microsoft Access and SQL Server.

The book next shows how to use an industry-leading data modeling tool to define and manage logical and physical data models, and how to create Data Definition Language statements to create or update a database running in SQL Server, Oracle, or other type of DBMS.

One chapter is devoted to illustrating how Microsoft Access can be used to create user interfaces to review and update underlying tables in that database as well as tables residing in SQL Server or Oracle.

For users involved with Cyber activity or support, one chapter illustrates how to extract records of interest from a log file using PERL, then shows how to load these extracted records into one or more SQL Server “tracking” tables adding status flags for analysts to use when reviewing activity of interest. These status flags are used to flag/mark collected records as “Reviewed”, “Pending” (currently being analyzed) and “Resolved”. The last chapter then shows how to build a web-based GUI using PHP to query these tracking tables and allow an analyst to review new activity, flag items that need to be investigated, and finally flag items that have been investigated and resolved. Note that the book has complete code/scripts for both PERL and the PHP GUI.

Rex Hogan has over 40 years experience as a database administrator and as a software engineer. This includes over 17 years of experience with Southwestern Bell/AT&T where he became their lead database specialist. During this period, he also taught various undergraduate and graduate classes at Washington University’s Center for the Study of Data Processing in St. Louis, MO. He then worked for TRW/Northrop Grumman for 16 years, primarily as a DBA/senior software engineer where he became a specialist in the rapid design and development of database systems and applications. Finally, he worked for five years as a computer scientist for the Air Force Office of Special Investigations, where he developed computer systems to monitor usage of USAF internet traffic. He has authored and co-authored several books, including A Practical Guide to Database Design (first edition), Diagnostic Techniques for IMS DataBases,and Managing IMS Databases.
