Shuei MEG review meeting, 2 July Framework Online ROME - Root based Object oriented Midas Extension Offline / reconstruction ROOT/C++ based  See Corrado’s presentation Monte Carlo simulation GEANT3 / FORTRAN77

Shuei MEG review meeting, 2 July New DAQ for Large Prototype DAQ computer divided into 3 PCs: 1. Front-end for trigger & data logging 2. Back-end for online analyzer, ROOT server 3. Run control, slow control & event display

Shuei MEG review meeting, 2 July Software Modifications for Large Prototype Online ROOT based analyzer Monitor online histograms thru network Offline Two analyzers: ROOT based & ntuple based kumacs are merged in the ROOT-analyzer Database : run catalog & connection table Testing to use ROME

Shuei MEG review meeting, 2 July Another CEX beam test at  E5 Further modification required DAQ using wave-form digitizer Database update during data taking  Run catalog  Hardware configurations  Cable connection, HV value, …

Shuei MEG review meeting, 2 July RDBMS CD title tune_title artist_name company_name Composer name category Tune title composer_name rating Artist name instrument Relational Database Management System  Table format database consists from several tables  Tables are connected with relations

Shuei MEG review meeting, 2 July SQL Standard Query Language Standard format of statement to access to database  SELECT title FROM Tune WHERE composer = “Juno Reactor”;  INSERT INTO Tune(title,rating) VALUE (“High Energy Protons”, 3);  UPDATE Tune SET rating=5 WHERE title = “High Energy Protons”;  DELETE Artist WHERE name = “DJ19”;

Shuei MEG review meeting, 2 July ROME Root based Object oriented Midas Extension Tool for Event based Data Analysis Fully Object Oriented Root based Full connection to the Midas Environment Online and Offline Based on Tasks, Containers and Folders for a good Data and Program Structure Experiment independent Base Classes Experiment dependent Classes are generated out of simple XML-Files The Users write only experiment specific code (physics) Administrative code is implemented in the generated code Self Documenting Code Self Linking Project

Shuei MEG review meeting, 2 July ROME Objects Folders Objects, where data is stored in Stores the data of one detector (or sub detector) component Hierarchically arranged Data inside of Folders is structured Tasks Tasks are objects, which provides actions They make calculations Store and read data in folders Fill trees and histograms Hierarchically arranged Task also own histograms Trees Data Objects : only written, never read Used to write data on files Histograms Graphical Data Objects : only written Belong to one Task Steering Parameters Task steering Framework steering

Shuei MEG review meeting, 2 July The ROME Environment experiment independent ‘ROME’-Classes o Base classes for the generated, experiment dependent classes ROMEBuilder o Builds all experiment dependent classes out of simple XML Files o XML files describe Tasks, Folders, Trees, Histos, Steering Parameters and Midas Banks o Links the generated project o Documents the generated project ROME classes XML File ROME classes Exp. classes ROMEBuilder Executable Documentation Project ROME Environment

Shuei MEG review meeting, 2 July Benefit of a Generated Framework Consistent Program Structure o All classes look the same o Better readability Less Handwritten Code o Code of a class is written once (in the builder) and reproduced many times Easier Maintenance o Modification are done once (in the builder) and then available in the whole framework C++/OO knowledge not required for programmers, just write code in C
