SNS global database use in application programming

A global relational database is being assembled to track accelerator components for the Spallation Neutron Source (SNS). As part of this activity, beamline element information is stored for use in high level application programs. A hierarchal accelerator framework is generated from the database and used for initialization of a Java based programming infrastructure. From within this framework input files for beam simulation codes can be generated using either live machine values or design values. The database also includes global coordinates for beamline element alignment, and magnet measurement data. An overview of the table schema and relationships to tables used in other parts of the project are discussed.
