In a career spanning more than 50 years, Charles W. "Charlie" Bachman has been an analyst, developer, architect, standards leader, and entrepreneur in computer software. He is best known for his invention of the first random access database management system, the Integrated Data Store (IDS). He was also the driving force in creating the first packaged enterprise resource planning solution, MIACS, and for establishing online transaction processing systems for large enterprises. Bachman also conceived of and introduced data structure diagrams in 1963 - known as "Bachman diagrams" - to provide a visual map of these novel data structures and a clear view of how to navigate them. He is an A. M. Turing Award recipient (1973), a National Medal of Technology winner (2014), and a Fellow of the Computer History Museum (2015).
