 - **Materialize** is a streaming database that maintains the results of queries incrementally, giving you views of your data that are always up to date.
 - **Cube** is a "headless BI" service that connects to databases or data warehouses and handles Data Modeling, Access Control, Caching and APIs

    a. Test out building a query with it in the Cube.JS Dev Playground at `localhost:4000`
 
-   b. Test curling the query to see how the REST API works
+   b. Test curling the query to see how the REST API works, the REST API uses a JSON schema that is demonstrated in the UI (see JSON Query tab):
+   ```json
+   {
+   "measures": [
+      "Vendors.totalRevenue",
+      "Vendors.totalOrders",
+      "Vendors.totalPageviews",
+      "Vendors.totalItemsSold"
+   ],
+   "timeDimensions": [],
+   "order": {
+      "Vendors.totalRevenue": "desc"
+   },
+   "dimensions": [
+      "Vendors.name"
+   ],
+   "filters": [
+      {
+         "member": "Vendors.id",
+         "operator": "equals",
+         "values": [
+         "24"
+         ]
+      }
+   ]
+   }
+   ```
+
+   So you can test it via a curl command like:
+
+   ```
+   curl localhost:4000/cubejs-api/v1/load -G -s --data-urlencode "query=$(cat example_query.json)" | jq '.data'
+   ```
 
    c. You can test the GraphQL API using the dev playground
