2. Andrea Chan FAC - RDBachan@slac.stanford.edu October 27&28, 2005 2 Components Database A single, comprehensive relational database for LCLS components. In the short term, we need a database to enable beam simulation, i.e. XAL The LCLS Controls group will be responsible for EPICS and XAL, which need parameters and metrics that can be stored in a relational database. The SCCS Database Group will design/implement the database schema, and supply the tools for data loading, data export, report generation and API’s. Use the PEP-II Components Database schema as a building block.

4. Andrea Chan FAC - RDBachan@slac.stanford.edu October 27&28, 2005 4 Advantages Flexible design that has been used to store diverse components without needing to redesign the database for each set of measurements and component type. The design and schema already exist. A copy has been customized for LCLS. (To reduce the number of tables involved for queries, customized views can be created.)
