Procedures in a database are stored code segments, which can be executed. This is a good way of holding any business logic in a single place. A procedure could be very simple and return the value of the square of two number, or be very complicated, and perform a lot of data validation before inserting data into a table or updating a table for example.
The procedures of a database typically include tasks such as data modeling, database design, implementation, querying, indexing, optimization, security, maintenance, and backup/recovery. These procedures are essential for ensuring data integrity, performance, and availability within a database system.
In an RDBMS (Relational Database Management System), the procedures are typically defined as a set of structured query language (SQL) statements that are stored and executed within the database. These procedures can include functions, triggers, and stored procedures. Functions are used to perform calculations or manipulate data, triggers are used to automatically execute actions when specific events occur, and stored procedures are pre-compiled routines that can be called to perform a specific set of operations on the database. These procedures help in maintaining data integrity, enforcing business rules, and improving performance.
Define the purpose and scope of the database. Identify the entities and attributes that need to be stored. Design the structure of the database using entities, relationships, and data types. Normalize the database to reduce redundancy and improve efficiency. Set up security measures and establish backup procedures for the database.
The five components of a DBMS are hardware, software, data, procedures, and users. Hardware includes the physical devices where the database is stored and processed, while software refers to the actual DBMS program. Data represents the information stored in the database, while procedures define how tasks are carried out within the system. Users interact with the system to input, retrieve, and manipulate data. These components work together to manage and maintain the database effectively.
In DB2, a user is an individual who is granted permissions to access and interact with the database, while a schema is a named collection of tables, views, procedures, and other database objects owned by a user. Users are associated with schemas to define their default schema for objects they create.
The database state refers to the current data stored in the database, including all records and their values. On the other hand, the database schema refers to the structure of the database, including tables, columns, constraints, and relationships. The schema defines how the data is organized and stored in the database.
Database administration
The database environment refers to the components inside a database. Some of these include hardware, software, data, as well as the procedures.
database user
Poor database security, no audit trail, non-validated database procedures, non-validated database install

Make sure the database does not run out of space. Nowdays no manual intervention is required in products from major database vendors like Oracle. Make sure the database jobs are running with no issues. Configure, Schedule backups Make sure backup and recovery procedures work as configured. Database security is another task.
A database management system (DBMS) consists of several components. Each component plays very important role in the database management system environment. The major components of database management system are: 1. Software 2. Hardware 3. Data 4. Procedures 5. Database Access Language..
1.support recover and backup procedures 2.support account setup and high security
