The database environment refers to the components inside a database. Some of these include hardware, software, data, as well as the procedures.
DBMS procedures, or Database Management System procedures, refer to the set of predefined operations or functions that manage and manipulate data within a database. These procedures can include tasks such as data retrieval, insertion, updating, and deletion, as well as maintenance activities like backup and recovery. They are often implemented as stored procedures in the database, allowing for efficient execution of complex operations and ensuring data integrity. Additionally, DBMS procedures help standardize database interactions, making it easier to maintain and manage the data.
