A database system is a collection of software and hardware components that manage and store data, allowing users to create, retrieve, update, and delete data efficiently. A Database Management System (DBMS) is software that facilitates the creation, manipulation, and administration of databases.

**Differences:**
- A database system includes the DBMS along with the data itself and the hardware, while a DBMS is just the software component.
- The database system encompasses the entire environment for data management, whereas the DBMS focuses on the management of the data.

A database catalog is a set of metadata that describes the structure of the database, including information about tables, columns, data types, constraints, and relationships between tables. It acts as a reference for the DBMS to manage the data effectively.
