What's the difference between BigQuery and BigTable?

Question

Why someone would use BigTable instead of BigQuery? Both seem to support Read and Write operations with the latter offering also advanced 'Query' operations.

Answer 1

Big Query is a query engine for datasets and it is used for large datasets. This will be used for a complete table scan.

Whereas Big Table is a database, this will be created for an application, and this can be a scaleable application. This will be helpful for the app that requires reading and writing data.
