# Description of the default test data

The default data loaded in MedCo is a small artificially generated dataset, appropriate to test a fresh deployment. The same data is replicated on all the nodes. Note that as of now it is encrypted using the test keys, i.e. the ones used for deployment profiles `dev-local-3nodes` and `test-local-3nodes`.

It contains 4 patients: 1 (real), 2 (real), 3 (real), 4 (dummy).

And 3 concepts: 1, 2, and 3.

The observation fact contains the following entries:

* patient 1, concept 1
* patient 2, concept 1
* patient 2, concept 2
* patient 3, concept 2
* patient 3, concept 3
* patient 4, concept 1
* patient 4, concept 2
* patient 4, concept 3

Example queries and expected results (per node):

* 1 AND 2: 1 (patient 2)
* 2 AND 3: 1 (patient 3)
* 1 AND 2 AND 3: 0
* (1 OR 2): 3 (patients 1, 2 and 3)
* (1 OR 3) AND 2: 1 (patients 2 and 3)<br>
