The databases that compose a database system are typically referred to as a "database schema." A schema defines the structure of the database, including the tables, fields, relationships, and constraints. It serves as a blueprint for how data is organized and accessed within the database system. Additionally, the entire system, including the database and the database management system (DBMS), is often referred to as a "database environment."
