  1. RDBOctober 27, 2005 • Outline • Components Database • LCLS Record Management • Component Names and Key Attributes • Summary

  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.

  3. Entity Relationship Diagram of the Components Database

  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.)

  5. Scope of LCLS Records Management

  6. Component Names and Key Attributes • Standardize alias names and map key attributes • Standard names will enable accurate linkage and search through other databases (e.g., CAD drawings, maintenance)

  7. Summary • Customized an existing Components database for use by LCLS Controls • Pilot use of Microsoft Sharepoint for document management and web collaboration tool Q4, 2005 • Action items: • Test the Components database schema and develop tools • Standardize component names, and maintain the alias names and key attributes in a central database
