Abstract: The instrumentation in use on the current generation of high energy astrophysics missions, such as the Chandra X-ray Observatory (CXO), is considerably more sophisticated than that of the preceding decades. The complexity of the resultant calibration data products requires an indexing strategy that is not ideally matched to the relatively rigid structure of the standard high energy astrophysics calibration database (CalDB). We have developed an enhanced design for the CalDB that generalizes the current structure and provides much greater flexibility in supporting sophisticated instrument models, while providing backwards compatibility. Development of mission-independent analysis software is enhanced by providing a mechanism for software to structurally query the CalDB to ascertain the set of query parameters needed to completely identify a specific calibration data product.
