| Definitionskos:definition | The Common DataBase (CDB) Specification provides the means for a single, versionable, simulation-rich, synthetic representation of the earth. A database that conforms to this Specification is referred to as a Common DataBase or CDB. A CDB provides for a synthetic environment repository that is plug-and-play interoperable between database authoring workstations. Moreover, a CDB can be used as a common on-line (or runtime) repository from which various simulator client-devices can simultaneously retrieve and modify, in real-time, relevant information to perform their respective runtime simulation tasks; in this case, a CDB is plug-and-play interoperable between CDB-compliant simulators. A CDB can be readily used by existing simulation client-devices (legacy Image Generators, Radar simulator, Computer Generated Forces, etc.) through a data publishing process that is performed on-demand in real-time.The application of CDB to future simulator architectures will significantly reduce runtime-source level and algorithmic correlation errors, while reducing development, update and configuration management timelines. With the addition of the HLA/FOM and DIS protocols, the application of the CDB Specification provides a Common Environment to which inter-connected simulators share a common view of the simulated environment.The CDB Specification is an open format Specification for the storage, access and modification of a synthetic environment database. The Specification defines the data representation, organization and storage structure of a worldwide synthetic representation of the earth as well as the conventions necessary to support all of the subsystems of a full-mission simulator. The Specification makes use of several commercial and simulation data formats endorsed by leaders of the database tools industry.The CDB synthetic environment is a representation of the natural environment including external features such as man-made structures and systems. It encompasses the terrain relief, terrain imagery, three-dimensional (3D) models of natural and man-made cultural features, 3D models of dynamic vehicles, the ocean surface, and the ocean bottom, including features (both natural and man-made) on the ocean floor. In addition, the synthetic environment includes the specific attributes of the synthetic environment data as well as their relationships.A CDB contains datasets organized in layers, tiles and levels-of-detail; together, these datasets represent the features of a synthetic environment for the purposes of distributed simulation applications. The organization of the synthetic environmental data in a CDB is specifically tailored for real-time applications. |
