1. Considerations about the BMS links to other OPERA systems Brick Manipulation Manager Links to other computing systems Needs to define the general framework Technical choices D.Duchesneau LAPP, Annecy OPERA collaboration meeting May 21st, 2003

2. The core of the system is called « Brick Manipulation Manager » or BMM. Its tasks are: communicate to the supervisor all commands and actions from the outside world retrieve the data which will be used to update the database information. do the communication with the external systems (OGC, BAM, cosmic bench, CS analysis…) REMINDER: (my talk of yesterday) Main functions of the computing system under development should be: To manage the life cycle of the bricks and CS and the manipulation information To save the relevant information into a database

3. > Supervisor/ Manipulator > BAM > (OGC)OPERA Global Control > OPERA On Line System > OPERA Scanning System > ManagerInterface ScanningInterface BAMInterface Brick Manipulation Manager(BMM) ManipulatorInterface Links between the various computer systems involved in the brick manipulation

4. What do we need: Wishes of external users concerning informations that should be available from the manipulation DB (apart from what I already described) Define communication protocol and programming language (interfaces with other systems): OPERA standards? Names of contact persons for the links to the following systems: Opera Global Control (or DAQ/OnLine) Brick information from the BAM CS scanning results ….. To know how those external systems plan their own development? Study and development of the interfaces (in collaboration with our team)

5. System analysis: follows the Unified System Development Process (USDP) method using the Unified Modeling Language (UML) (cf: yesterday’s talk) Database : the choice goes to ORACLE. It seems to fit the needs and follows preference which has been already suggested in OPERA. Operating system and platform for the BMM : the choice will follow the standards choosen by the collaboration, all possibilities should work (PC with Windows, Linux…..). Programming language : C++ and/or Java for the users interface Communication protocol: IP on Ethernet…. Technical choices:

6. It is time now to start this work and to join the effort! Names of contact persons Opera Global Control (or DAQ/OnLine) ? Brick information from the BAM ? CS scanning results ? define OPERA standards and strategy
