 Database (DB): An organized collection of data  Database Management System (DBMS): Software system that manages databases  Database Model: Structure of the data in a database Hierarchical, Network, Relational, ER, Object, Dimensional etc  Relational Model: Based on mathematical relation (set theory)  Relational DBMS: DBMS based on Relational Model Ingres, Oracle, DB2, MySQL, Postgres etc Terminology V. Vuppala, Controls DB Meeting, Slide 3

Information Architecture, Slide 4V. Vuppala, Controls DB Meeting  Application layer Operator interfaces High-level applications Libraries  Service layer Access to data Programming Interface  Data layer Managed data No direct access RDB, Files, No-SQL etc

Distributed Components, Slide 5V. Vuppala, Controls DB Meeting  Distributed across the network Data Services Applications  Scalable

 Keep the schema as simple as possible.  Do not model every small piece of the facility.  The operational database must be in sync, or very close to, the real facility. So it should be easy to update the database.  Updates to the database should be controlled but not overly cumbersome.  The schema should be generic, to an extent, so that other labs can use it. However, it should not be at an inordinate cost.  It should be possible, for other labs, to use parts of the schema, possibly by having a set of loosely-coupled subschemas or “domains”.

Components V. Vuppala, Controls DB Meeting, Slide 10  Physical Component: This represents physical entities; things that exist in the real world. Example: the cavity with part number T30802-MDE-0008 that was manufactured by Jefferson Lab is a physical-component.  Conceptual Component or Component Type This represents generic entities or concepts and their designs. Example: horizontal electrostatic dipole, beam current monitor, RFQ, and RF cavity  Configuration or Logical Component It represents the entities that exist on the blueprint or configuration of the FRIB facility. Example: the cavity LS1_CA01:CAV2_D1101

 Two “Flavors” of IRMIS Systems Controls-based IRMIS (IRMIS-C): Excellent GUI, stable releases Physics-based IRMIS (IRMIS-P): Physics schemas, data loading scripts  IRMIS-P closer to FRIB Schema Configuration-component – install Physical-component – component Conceptual-component – component-type  Ideal situation Everyone agrees to one core schema The GUI can be “ported” to new schema  What all changes are need to IRMIS-C and IRMIS-P? Mapping to IRMIS V. Vuppala, Controls DB Meeting, Slide 29

 Possible solutions RDBMS (Relational Database Management System) »Oracle direct path, partitioning »Integrated access SciDB: open source high performance database for scientific problems Hypertable: open source distributed high performance data storage Cassendra: open source distributed high performance database (apache)  Other labs BNL looking into SciDB and Hypertable BNL goal: 1M PVs at 1hz forever SLAC has tried RDBMS SNS is using Oracle (93K PVs) Archiver, Slide 30V.

1.Understand and accept that you will make mistakes. 2.You are not your code. 3.No matter how much "karate" you know, someone else will always know more. 4.Don't rewrite code without consultation. 5.Treat people who know less than you with respect, deference, and patience. 6.The only constant in the world is change. 7.The only true authority stems from knowledge, not from position. 8.Fight for what you believe, but gracefully accept defeat. 9.Don't be "the guy in the room." 10.Critique code instead of people—be kind to the coder, not to the code.
