How to create a simple design of student exam database in according to the object oriented database management system model?

If we create a simple design of student exam database in the perspective of object oriented database management system model then what kind of attributes and classes in the database can follow in the diagram object oriented management system model?

The student exam database

How to create a simple design of student exam database in according to the object oriented database management system model?

It is hard copy of student database and their records. It contains basic detail related to the student and their environment of student. It helps to maintain the mark sheet record of every student in the particular class of student. There are some basic attributes and classes related to the student exam database object.

The Name of student

It is a class related to the student exam database which connected with strong line. There are three fields in the class of ‘name of student’ following below

First name, middle name and last name are fields that hold the character data type.

{First name = Character data type}

{Middle name = Character data type}

{Last name = Character data type}

Roll number

It is a Strong attribute of the particular student of which can help to easily find the record of the student in the database of student exam. It holds the both types of data type such as character and numerical.

{Roll number = Character and numerical data type}

Postal Address

It is an attribute of student that helps to find with the combination of two records from the student record. Such as compare with the parent name data and student address which is known as composite data attribute. But here the ‘Postal Address’ is the class in according to the object database and there fields are following below with types of data type.

{Plot number = Numerical data type}

{Street number = Numerical data type}

{City = Character data type}

{State = Character data type}

{Pin code = Numerical data type}

Photo of Student

It is image attribute of student which can identify by their face of real time of the student. It very strong attribute without their unique identity number of student as a roll number in student exam database. It depends on the size of the image with their recommended criteria in the field of image box. It also requires the format of the image such as jpg, PNG, jpeg etc.

{Photo of student = GIF data type}

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 ...

What are the three main purpose of an operating system?

What are the three main purpose of an operating system? There are three main purpose of an operating system. 1. The first main purpose is User interface between hardware and users. 2. The second main purpose is to operate the internal parts of the computer properly and systematically using binary code system in the form of 0 and 1. 3. The third main purpose is to provide an environment for development of an application software and program to uses the hardware resources of the computer and connected to the computer parts which provides output to the user, the output from application software is very useful for users. Interface between user and hardware device  The operating system uses all types of interface such as command line interface, batch command interface and Graphical User Interface to interact with users to hardware peripheral devices through the monitor screen. Monitor has a big role making interface between hardware and users. Monitor visualization of all types ...
