Aim
• Aim is to keep track of each (expensive) component:– Sensors– Hybrids– Modules– Ladders
• => Logistics: Registration, Shipments, Assembly
• Add measurement results23 July 2012
Belle II SVD Construction Database
3Thomas Bergauer (HEPHY Vienna)
Implementation
• Web-based software written in CakePHP (framework based on PHP)
23 July 2012
• Running on HEPHY webserver– http://www.hephy.at/hephydb
Belle II SVD Construction Database
4Thomas Bergauer (HEPHY Vienna)
Key features
• User access system (benefit of CakePHP framework)– Authentication
– User/Group permissions
• Logistics Module [already implemented]– Registration: “Add item”
– View Inventory of one or all “locations”
– Location is e.g. HEPHY, KEK, IPMU,…
• Measurement module [not yet implemented]– Store measurement results
– Retrieve data with nice-looking plots
• Administration Module [already implemented]– Add/change/remove users and groups
– Add new “locations”, “item types”,..

Let’s have a look to each of those…

User access system
• Individual user accounts
• Linked to location, e.g. user Bergi=HEPHY

Logistics Module
To view and search for inventory.
Works only if • Each new component is
entered– “Add item” page
• Shipments are entered– “Transfer” page
• Assembly steps are followed in the db– “Assembly” page

Administration Module
Add/edit/delete• Locations• …..• Item types, e.g. make
the DB know that a “2-DSSD-origami” module needs to consist of two HPK sensors of type “large rectangular”

Measurement module: not yet implemented
• Upload measurement results as ASCII files directly to web server (HTTP POST command).
• Will be done – directly from measurement software (e.g. Labview)– manually (at a later stage)
• Uploaded ASCII files will be parsed at server side and data will be put into database
• Query module will allow to retrieve data (e.g. position of non-working strips) and nice-looking plots (e.g. IV curve on sensor)

Summary
• Web-based logistics database for SVD has been implemented at http:/www.hephy.at/hephydb
• Logistics module is basically working with “view/search item”, “add item”, “transfer item” and “assemble items”
• Only useful if every single action is followed in both, reality and database
• Next SVD meetings: I will distribute passwords for KEK, IPMU,.. and ask people to start enter data (e.g. how many HPK sensors are available)
