Collection Management

Collections allow for storing different types of data in your IoT solution.

Collection Creation

By going into our IoT System and clicking collections we can view our different data stores.

To create a collection click the “Add Collection” button and provide a name,type and source of data and click create.

Its possible to alter the schema of the collection by clicking Edit Columns. With the dialog open we can add columns to it. Enter a one word column name, and select the corresponding data type from the dropdown. Click Done when finished.

Now that schema is altered, lets add an item to the collection by clicking on the + add row button.

The new item has a unique item_id generated and the other columns are empty.We can then provide values for each item in the collection.To enter data into the row, click the cell corresponding to the row and column.

Collection Security

Each collection is available for users and devices to access via Portals, APIs and SDKs, but by default the collection has all access privileges turned off. By going to the settings on the collection we can provide update the associated role access. In this case we are going to give Authenticated users the ability to read, create, update and delete from this collection. Now we can use a very basic API call from a curl statement to access this collection. Notice the authtoken that is valid for authenticated user. When we submit this call we get back the full dataset, but if alter the key to be invalid the request will come back with security error
