  • DB2 is a relational database management system (RDBMS) that can be used to manage a wide variety of data, including images, audio, and video. It is supported on the NIH Data Center’s mainframe system (Titan). DB2 is especially effective at handling data that need to be stored securely, data that need to be manipulated and analyzed interactively, and data that are the basis for one-time and recurring reports. Data input, update, storage, security, extraction, analysis, and report generation are all facilities of DB2.
