Querying your Datasets
To retrieve data from your datasets, you need to define a 'query' with the Geo-visualization REST API query language. Queries allow you to aggregate, transform, filter and sort the data before it is consumed by your visualization.
Queries fit into the flow of a visualization design as follows:
- An authenticated user uploads a dataset, and remains the dataset owner.
- The dataset owner defines a query on the dataset.
- The dataset owner requests the results from the query in the visualization app.
- The dataset owner publishes the query so that non-authenticated users can request results from the query.
The following sections describe the process of defining and using queries.
