The Gemini Data Handling System developed by the Canadian Astronomy Data Centre for the Gemini telescopes provides the data handling infrastructure for the Observatory Control System and the instrument control systems. An overview of the preliminary design was presented at ADASS '95. In August 1998, the DHS passed its acceptance tests and was released operationally to Gemini North in Hawaii. This paper will present a case history of the project, on how the requirements changed, on how the design evolved through to its final form, on the approaches taken, on the tools used, and on the problems encountered.
