Let us discuss about categorization of object in database management system?

What do you understand by the categorization in DBMS?

What do you mean by categorization of object in DBMS?

  • Object has so many properties and entity relationship model can express their properties.
  • Object has properties to categorize by declaring the classes in the database.
  • Sub-classes are also categorizing the object characteristics in the database model.
  • Categorization of object is reduces the value of number in counting.
  • It can be benefit to the grouping of the object such as gender of same person, city of employees and street of the student in a same class etc.
  • The categorizations of the objects are very useful for easily to find the unique object if the unique identify have not yet at a time of the object attributes.

In the categorization the sub-class is known as weak attribute under the strong attribute in the database model such as you can say ‘state’ is a weak attribute but the strong attribute is their ‘complete address’ of the person object lives in the state.

Object has so many properties in DBMS model

Let us take the object as a student of school.

So there are so many attributes of the student in the school which can relate from the school's attributes.

Such as "classes" of every student who is studying in the school. The class is the attribute of the student. The student daily comes in the class of the school and studies in the particular class room with their section as declared by the school. 

In the example the student has categorised by their class room and section of the class in the School.

In the school database it reduces the numbering of the student object in the school from the single database of the school and categorised by the class and section. 

This means the categorisation of the student in the school by the classes and section of the classes to reduces from single database of the school.

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 ...
