 ## Query your data
 
-See below how to query the data in Iceberg using Apache Spark.
+Verify that your data is accessible using a query engine that supports Apache Iceberg tables, such as Apache Spark.
+
+List the tables in the `postgres_main_public` namespace:

+
+The output shows the available table names; here, the table is `sample_data`.
+
+Inspect the table's columns and data types:

+
+The output lists each column and its Spark data type.
+
+Check the Iceberg table's storage location in SeaweedFS:

+
+The `Location` row shows where the table's Iceberg data is stored:
+`s3://warehouse/postgres_main_public/sample_data`.
+
+Read a few records from the table:
