Tim Gorman began his information technology career in 1984 as a C programmer on UNIX and VMS systems, working on medical and financial systems as an application developer, systems programmer, and systems administrator. He joined Oracle Corporation in 1990 as a consultant, then became an independent consultant in 1998, and has worked for SageLogix since 2000. Gorman is the coauthor of Essential Oracle8i Data Warehousing and Oracle8 Data Warehousing. He specializes in performance tuning applications, databases, and systems, as well as data warehouse design and implementation, backup and recovery, architecture and infrastructure, and database administration. Gorman still considers himself a pretty good coder, although the market for C programs has dried up somewhat lately.
