Carl Eric Johnson
Carl is an accomplished database designer, systems analyst, application programmer, database administrator, and technical instructor with an uncanny knack for demystifying complex concepts for his clients, colleagues, students, and friends. He is equally comfortable with legacy mainframe systems, emerging Web 2.0 technologies, and everything in between, including Windows, Linux, and Mac. His decades of experience with IBM's DB2 (mainframe and Linux/UNIX/Windows) are augmented more recently with MySQL and SQL Server. He has been called an "SQL Guru" on all standard platforms.
