### What is the catalog ?

Everytime we scan data, SmallID maintains a stateful view of the objects and findings. It's like a central repository for all the metadata SmallID was able to collect during its scan process. Please note that SmallID (or BigID) never copy your actual data from your data sources.
### Identify S3 objects where Credit card information is present

In order to do this, you can do the following query in the catalog. Try to find on the left menu "classifier.Credit Card (Narrow)".
