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?)

If you find this list incomplete, please add your devices or tests to the manual.
The structure and format have not been fixed yet....
