Describe the function of a distributed database with an example applied on the Distributed database system?

What is the function of a distributed database?

Distributed database is a type of database technology that provides the flexibility of access information for the client user or admin user.


Distributed database provides many servers to access the information on the website or a particular computer system.


Distributed database accessed from the website functions of query programs to manipulate and retrieve the database


Describe the function of a distributed database with an example applied on the Distributed database system? What is the function of a distributed database?

The multiple location situated servers of the database provides the distributed data to recover or access the information from the nearby server which reduces the latency of data transfer to the computer system of the client user.


The manipulation commands can be applied on the distributed database such as:- updating the database file, records deleted or changing the information, insert the new record into the table of relational database model which is distributed on the distributed server to the multiple location.


The distributed ledger is based on the distributed database technology for the blockchain maintenance of the transactions of the record in the lists.


For example:- the manipulation command applied on the record in the database file in the relational database model using the SQL program language following below here:


//Create a table with employee db name


CREATE TABLE “EMPLOYEE_DB”;


INSERT INTO ( “ID”, “NAME”, “AGE”)

VALUE ( “1”, “Steve”, “45”);


SELECT NAME, AGE;


Output from SQL in the table EMPLOYEE_DB following below here:-


Steve , 45 


This is an output that comes from the SQL command applied on the record which is created by the insert command into the relational database model in the database file in the table name “employee_db” and these two commands are used from the data manipulation command or (DML) from the SQL server programming on the application which is used in the distributed database system to access and store the data or values into the record on the database file in the table and also it is retrieved from the select command which is working behind the user interface of the application software or web application or website in the distributed database management system.

It is an example of how the SQL commands are working for the backend processing system on the Web application or website or application software for the client user when the user wants to access their information from the relational database model in the distributed database system.


Introduction to the computer related topic of computer application and system technology topic is following below here:


What is the function of a distributed database?


Let’s discuss this topic following above the related topic of computer application and system technology and explanation following below here:


What is the function of a distributed database?

There are some points on the computer system and database applications related to the topic of “What is the function of a distributed database?” following below here:


  • Distributed database provides a flexibility of the data retrieve from any server of database
  • Distributed database cannot be lost because it has a backup of data to receiver from the other server of database to access the backup database
  • Distributed database also provides the backend processing on the website services for the client user
  • Distributed database access the information from the nearby server of database to provide information for the client user on the website 


Let’s discuss the points listed above about the computer system and database technology related to the topic of “What is the function of a distributed database?” explanation following below here:


Distributed database provides a flexibility of the data retrieve from any server of database

The distributed database stored the copy of the data to the multiple servers of the database to be accessed by the user when they want to retrieve the database from the nearby server of the database.


The replication of the data is known as the copy of the data which is used to distribute to the other multiple servers of the database in the distributed database management system.


When the nearby server accesses the copy of data or information by the client user or admin user reduces the latency or improves their performance such as:- fast accessing the information and gives a best performance of processing the data from the nearest server to the user.


When data is divided into many parts of the information or many pieces of information then it follows some patterns to access the complete information or the database from the pieces of information which is collected from the nearby servers to provide the complete information or database.


Distributed database cannot be lost because it has a backup of data to receiver from the other server of database to access the backup database

If the data is replicated which means the data created many copies and distributed to many servers which is used to protect from the data lost if one server has been damaged for any reason then the other servers of the database provide the copy of data which is replicated data in the distributed database management system.


If the distributed database server does not work for the user then the other redundancy of the server provides the copy of data or replication of the data and processing the data due to the nearby server for the user on the distributed database system. This protects from the hardware failure, network problem loses its data when it doesn't work.


It provides the backup recovery system of the database because the other database server provides the replicated database for the user which means the database cannot be lost from the distributed database system for the client user or admin user.


Distributed database also provides the backend processing on the website services for the client user


Distributed database also provides the backend system for processing the database of the website to provide the output data using the query performance applied on the application program and user interface of the application to get the output data using the backend processing system.


The distributed database system provides the backup and recovery system which protects from the data lost of the website or client user or admin user. Such as:- video database, text documents files, image database files, audio database files etc.


The distributed database can provide expandable feature which is known as scalability of the distributed database to provide the system of adding the new servers in the distributed database model to increase the area of distributed database processing for the website business projects or other types of services for the client user or admin user to increases also the performance of the database processing system.


The distributed database also provides the reliability of the database system to enhance the security options and provide more security due adding the new servers of the database to process the security database for the client user or admin user.


Distributed database access the information from the nearby server of database to provide information for the client user on the website 


Distributed databases access the information when the user wants to access the information from their distributed database then the distributed database system provides the nearby server and their functionality of the web application or website or any type of program that provides the functionality to provide the output data.


The smoother performance and faster accessing the information from the nearby geographically for the client user which increases the best performance for the user in the form of services on the website or web application to perform a task then provide the output data to the output interface as a solution.


All servers cannot be accessible to load the database for the single client user on the distributed database model because it increases the buffering or latency of data transfer for the client user and number of copy of data cannot need for the client user, so it only provide the nearest server of database for processing the data for the client user on the distributed database model.

Discuss the role played by the various components of the CPU

Q Discuss the roles played by the various components of CPU? The CPU is the brain of the computer system. All major calculations, manipulations and comparisons are made by the CPU. The CPU is also responsible for activating and controlling the operations performed by all other units of the computer system. The major components of the CPU are: a) Arithmetic Logic Unit (A.L.U.) b) Control Unit (CU) c) Primary Memory Arithmetic Logic Unit (A.L.U.): What is ALU Arithmetic logic Unit? ALU is a part of the CPU. It is a part to calculate the logical term in the CPU where the term refers to an operation of logical type. It also calculates the arithmetic terms in the CPU where the term refers to an operation of arithmetic type. It is used to direct access through the processor controller. The ALU connected to the input and output peripheral system through the bus with the different types of bus. Such as control bus, data bus etc. ALU is a part of the CPU that can calculate the input...

About the memory and its Classification of the computer Memory

What are the memories in the reference of computer system? What is Computer Memory?:- The memory is the essential for the computer to store the data, instruction and information. Without memory, computers are not be able to store data, instruction etc. The memory is an essential part of a computer system. It is require by the computer system to store information. Memory can be divided into the following two categories types: i) Primary or Main memory ii) Secondary Memory or Permanent memory In this figure I'll show the classification of the memory of computer system peripheral and architecture of organisations Primary Memory or Main memory:- i) Primary memory is the memory which is fastest memory of the computer. ii) It is a small but relatively fast storage unit that stores data and instruction which are used by the CPU (central processing unit). iii) This type or category of a memory is the main memory of the computer.It is a temporary memory and also we ...
