ABOUT THE AUTHORIt all started when my supervisor called me in to her office and handed me aninstall disk, or more correctly a floppy disk, of a database system and said "Ineed you to learn this."This request was not entirely random. I had dabbled with programming off andon throughout my youth with my father's TRS-80 Color Computer. I hadworked myself up from delivering coffee and paper clips to the home lendingdepartment of a local bank. In that department opportunities arose for me to usemy programming skills for automating mundane tasks which was motivated bythe desire to never see an IBM Selectric typewriter again.With this experience behind me, and my supervisor's request pointing the wayto my future, I accepted the disk and eagerly began to cross that threshold intothe wonderful world of databases. As the years passed and I began to learn andunderstand normalization, data modelling, data transformation, interfacedevelopment, data warehousing, backup and recovery, performance andsecurity, my love and passion for this new world quickly grew.Through this nearly twenty year journey, I have been able to create databasesystems for the benefit of the banking industry, State government, and morerecently heading the Data Services group of one of the fastest growingbusinesses in the United States.The technical community was there for me in my formative years offering medeeper explanations of concepts and sharing of ideas with peers. I considermyself very fortunate to give back to this community for the benefit of otherswho are now where I was many years ago. Through my participation as a cofounderof local organizations such as the Indianapolis ProfessionalAssociation for SQL Server (www.IndyPASS.org) and IndyTechFest(www.IndyTechFest.org) my home town of Indianapolis is one of the mostactive SQL Server communities in the country. In wider circles of influence Ihave authored articles at DevX.com, provided snack-style instructional videosat JumpstartTV.com and presented on sensitive data solutions at SQLSaturday events.You can find my latest contribution to the sensitive data dialog at my blog:http://www.simple-talk.com/community/blogs/johnm/default.aspxxii
