# Accessing Data
Once data is registered through the PostgreSQL connection, you will access your data through your PostgreSQL client as you normally would. If you are subscribed to the data source, Immuta grants you access to the data in PostgreSQL.
When you submit a query, the PostgreSQL client submits the SQL query to the PostgreSQL server, which then processes the query and determines what data your role is allowed to see. Then, the PostgreSQL server queries the database and returns the query results to the PostgreSQL client, which then returns policy-enforced data to you.
The diagram below illustrates how Immuta, the PostgreSQL server, and PostgreSQL client interact to access data.
