Database

This chapter summarize the DEgg data storage. All data are stored in json format and linked each other by id. Json files are on grappa in:

/disk0/users/icecube/degg_database/json_files/

We will connect to the Madison based mongoDB server for our json inserts.

There are two mongo collections: Devices and Tests.

Devices collection has any physical device or part of larger device. The following are the content of each directory in Devices directory.

Tier-1. Full modules

Tier-2. Sub-assemblies

Tier-3. Low level parts

Tests collection has any test results from a Device. Tests can link to a device_id. (or device_type for glass and gel?)
