Well, it is SQL based data analytics in the Cloud. Whether it is properly Big Data may be debatable, since to me that suggests data scientists collecting and figuring out how to analyze data at a macro level. But BigQuery is certainly data analytics, and that is a valuable tool for almost any business, if utilized properly. That is the "catch", you get results based on the data you put in and your query, so if you don't know what you are doing, you aren't always going to get a useful output. Also, it doesn't look like BigQuery provides any visualization of data, so you probably will have to export the data and use another program for visualization.
Still, because it is in the cloud you can use it anywhere, and with a variety of devices, so it is particularly worth looking into if you aren't always at a fixed desk.
