The buildPackage table of the rd_releasemgr database holds the list of all the software packages that have been built by the RM and their associated buildPackageId. A build package, with a given buildPackageID, is differentiated from other by its packageId, versionTypeId and version values. The packageId and versionTypeId are the key values from the package and versionType tables respectively. The version is a unique value that is a number for Integration and Release Candidate builds or a tag value (of the form VV-RR-PP with an optional -bbbb branch tag at the end) for Release builds.
The table also contains the path to the doxygen documentation for the build and flags for whether or not the build's tag still exists in CVS and whether or not the build should be visible in the various display software (RMViewer and the web pages)
