The Common Database (CDB) specification is an open synthetic environment database specification managed by Presagis. CDB was developed specifically to solve recurring database issues related to publishing speed, correlation and database re-use. The CDB Specification addresses these and other issues through a common database specification. It is intended as a simulation specification for use in producing a unified synthetic representation of the world. A database built to the CDB specification is referred to as a Common Database (CDB). A CDB is a single-copy data repository from which various clients are able to simultaneously retrieve, in real-time, relevant information to perform their respective runtime tasks, either for simulation or other purpose.
CDB was originally developed for the U.S. Special Operations Command (SOCOM) by CAE in 2004. A key driving factor for CDB is SOCOM's requirement for very rapid database generation for on-the-fly mission rehearsal in flight simulators, primarily special operations helicopters.
CDB solves the long-standing database problems in the market related to database re-use, correlation, and publishing speed. Using CDB, developers may create databases which can be openly exchanged, quickly updated and stand the test of time. The value for the end user is represented in the form of speed of updates or changes to the database based on new requirements, as well as the ability to add new clients without having to redesign the database or develop an entirely new database. This translates into faster updates, lower costs and a better simulation end product.
CDB is unique in that it is an open database format, a source data repository and a runtime publishing format all in one:
There are no other common database formats that include all three of these characteristics.
The overriding goal for CDB was to dramatically reduce the time it takes from the receipt of new source data to rehearsing a mission in a simulator. Today, CDB solves five key market problems related to database creation and maintenance:
The company believes in the value of open standards and CDB provides the ideal database standard to complement its existing portfolio. The company views CDB as an enabling technology to facilitate integration between its COTS products and provide a common platform that will translate into tremendous productivity gains to customers. Customers will see CDB adopted by key flagship Presagis COTS products in the near future.
Yes. CDB is an open standard and any third-party may choose to develop to the standard and provide software applications and tools compatible with CDB.
Absolutely. Popular standards such as OpenFlight and TerraPage will continue to be maintained and improved as long as the market requires.
No. Customers who wish to continue using Presagis tools with existing standards such as OpenFlight, TerraPage or other may continue to do so. The Presagis goal is to drive adoption of cutting edge technology and solutions while continuing to meet the needs of the broader market. Presagis sees CDB as a standard that will drive new, more innovative and efficient ways of working. The goal is to enable our customers to leverage this type of advanced functionality when/if they are ready to move in that direction.
