How Database Management Systems work on a computer system?
Database management system is a type of server application software that is used to process the data in the relational model to provide the output data on the tabular form of data to the row and their field mentioned with the record and their attributes that contains a value to define the data of the subject or object inserted into the cell in the relational database model.
Database management system for the user can process the data through the commands applied on the DBMS server application software.
The data command is also known as SQL that includes the different types of keywords which is a command to perform an operation on the database file in the Database Management System on the computer system.
The data can be processed through the database programming to provide the result on the database file on the particular software system such as:- web application, application software, website and the operating system on the computer system.

There are some points on the computer system and database technology related to the topic of "How Database Management Systems work on a computer system?" following below here:
- Database is used to process the data in the relational database model
- Database uses the record to process the data of attributes
- Data can be manipulate using DML
- Data can be defined through the DDL
- Data can be used for security purpose for processing the verification system
Let's discuss the points listed above about the computer system and database technology related to the topic of "How Database Management System works on a computer system?" explanation following below here:
Database is used to process the data in the relational database model
The relational database model is used to process the data on the DBMS server application software that is used to apply the SQL program to process the data using the commands on the database file in the relational database model.
The relational database model is used to process through the SQL and the SQL included the different types of commands are: DDL, DML and DCL.
Database model of relation included the row and column to provide the table format of the database file.
The relational database has a row is known as a tuple or record and the column is an attribute, property or field on the relational database model. The record is used to describe the subject and object depending on the text data on the relational database model and the attributes are used to describe the property of the subject and object.
The relational database model processes only the text data.
Database uses the record to process the data of attributes
Database uses the record to process the data of the attribute to provide the property on the record to describe the details of the subject and object depending on the data inserted into the cell. The cell is a combination of the record and attributes where they cross and make a section or box that describes the cell of the record.
Record has infinite values of attributes that describe the detail depending on the data and its types to insert into the cell of the record according to the attributes of the records in the database file of the relational database model.
The record is a row that is described by the attributes and the key attributes are applied to uniquely identify the records on the relational database file.
Data can be manipulate using DML
Data can be manipulated using the DML means the Data Manipulation Language to process the data on the relational database model.
DML is used to provide the manipulation operation on the database file to provide the output data using the manipulation language operation applied on the record of the relational database model.
The DML is used to provide the management of the data on the relational database model file. The manipulation commands such as:- select, delete, update etc.
These are the DML commands that are applied on the records and the attributes to change or manipulate the value on the relational database model on the computer system.
Data can be defined through the DDL
Data can be defined through the DDL that means the DDL is a data definition language that is used to define the database file on the DBMS.
The SQL provides the DDL to provide the definition of the database file and define the relational database model to insert the new data on the file to provide the output data after the processing system on the database file.
DDL is used to define the data on the DBMS application to provide the file for using the file in the application software for new option or program to store the new data because the defined database file is blank and need to insert a new data on the database file on the DBMS server application software on the computer system.
Data can be used for security purpose for processing the verification system
Data can be used for security purposes for processing the verification system on the application software to provide the security layer to verify the data on the database file.
The database file is used to process the data using the data control language or DCL from the SQL which is a type of SQL to control the data and provide the verification system on the application software.
The DCL is used to provide the logical system to grant the user permission to access the user account on the application software is a common example of the application software. The database file is used also for providing the security layer on the application software and the user can access the account after verification of the attributes of the record which is inserted into the user record in the relational database file.
Such as:- username and password is a type of attribute to provide the verification process.
The key attributes have a major role to verify the record and their attributes of the verification on the security model of any types of software systems on the computer.
The key attribute record is used to define the record’s property as a unique value in the columns and provide the verification system on the security interface and program for the client user on the software systems.
