2. GEM Database Framework
GEM Database framework consists of 4 components
GEM Database: Used to store data: Two instances:
Development—INT2R
Production—OMDS at P5.
GEM DB Loader:
It is used to load data into database.
It has spool area in which XML / Zip Files are copied. Dbloader load these files into database.
GEM Web Interface (GUI):
GUI to load data:
Registration of parts
Construction of Chambers/ Super chambers
Load data regarding various QCs, configuration of components / detectors etc.
GEM OMS (Online Monitoring System):
Data Visualization Framework
Enables users to view & retrieve DB contents without having to learn DB specifics

3. GEM Database: Accounts & Schemas
Following DB accounts defined and corresponding schemas deployed (in each instance)
CORE Schemas
CMS_GEM_CORE_CONSTRUCT store detector components
CMS_GEM_CORE_ATTRIBUTES store attributes of components & conditions
CMS_GEM_CORE_COND store metadata
CMS_GEM_CORE_IOV_MGMNT store configuration keys, IOVs, Tags, etc.
CMS_GEM_CORE_MANAGEMNT store management info – location, institution, etc.
User Schemas
CMS_GEM_MUON_COND to store tables for all user generated data
CMS_GEM_MUON_VIEW to store all database views
 CMS_GEM_MUON_CONSTRUCT rarely used

4. GEM DBLoader Predefined XML templates.
Copy files into spool area of dbloader.
Dbloader loads files into database
Check status of file after copying

5. GEM Web Interfaces (GUI)
Separate Graphical User Interface for INT2R (Development) and OMDS (Production) DB
Dev DB GUI
Prod DB GUI

6. GUI Overview
GUI for entering detector construction data is fully functional.
It is used to load various detector components to build chamber and super chambers.
All the production sites will use this interface to construct chambers.
Also deals with Quality Controls

7. GUI Overview Register parts
Foils, Drifts, Readouts, VFATS, GEBs, External Frames, OptoHybrids, Cooling Plate Circuits, Temperature Sensors, Radmon Sensors etc.
Attach parts.
12 VFATs to GEB Narrow
12 VFATs to GEB Wide
Construct Chambers and Attach Parts
3 Foils
1 Drift PCB
1 Readout PCB
GEB Wide and Narrow
Optohybrid
Frames
Cooling Plates Circuits
Temperature Sensor
Radmon Sensor
Attach/Detach child parts from parent parts
Build Super Chambers
Attach / Detach chambers to / from super chambers

8. Add / View Components Readout boards GEM electronic board GEM Foil
OptoHybrid
Drift boards
VFAT
GEM external frame
GEM AMC board
GEM Cooling Plate Circuits
Temperature Sensors
Radmon Sensors
GUI generates relevant xml file and sends it to DBLoader after user submit form.
Dblaoder loads this file into database.
Users can directly send xml/zip files directly to Dblaoder if in case of bulk data upload.

9. Attach/Detach VFATs to GEB
Edit Page of GEB
12 VFATs to GEB Wide
12 VFATs to GEB Narrow

10. Chamber Construction
Once we add all the components, we can start building a chamber.

11. List/Edit Chambers View list of chambers
Show option displays a chamber’s detail.
Edit option for attachment/detachment of components to / from chambers.

12. Attach/Detach Components to / from Chambers

13. Super Chamber Construction
Need two chambers to build super chamber
Attach two single chambers

14. Attach/Detach Chambers to / from Super Chambers
Edit Super chamber page to attach / detach chamber to super super chambers

15. Quality Controls Interface for uploading various QCs data.
Users provide relevant excel file for different QC.
GUI converts excel file into relevant xml files and sends them to dbloader for uploading into database.

16. Detector Construction

17. Online Monitoring System (OMS)
OMS is used for data visualization.
It displays data about the results of QCs and other stuff.
URL to access OMS for GEM is:

18. Online Monitoring System (OMS)

19. Online Monitoring System (OMS)
Workspace – top-level object in the hierarchy of content organization.
Can represent a CMS detector logical or organizational units,
sub-detectors, etc. For example, CMS, GEM, Pixel, Tracker, HCAL, CSC.
Folder – hierarchical container (lower-level) for Pages. For example,
Quality Control, DAQ, ConfigurationDB etc, etc.
Page – actual content container that is composed of a single Controller (optional) and one or more Portlets. For example, Run Summary, Report, etc.

20. Online Monitoring System (OMS)

21. Conclusion & Future Work
