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.
Procedures in an RDBMS are programs that are written to accomplish a set of functions that cannot be done using a single query. A procedure contains a sequence of SQL Queries that can be executed one after the other by invoking the procedure. There are two kinds of procedures Functions & Stored Procedures.
The basic steps in planning a database are as follows:Collect informationIdentify key objects or entitiesModel key objectsIdentify the types of information for each object or entityIdentify the relationships between objects or entities
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 schema is the description of the database. It defines how the database is set up and what data it is to contain and control. This description is given to the DBMS to manage the data. The database state is an image of how the database looks at any given time. The database schema is set unless you change how the database is structured. The database state will change whenever new data is entered into the database and the database is updated.
Database administration
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.

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..
