Disadvantages or drawbacks of the Relational Database Management and System

If the key attributes of the relational database are fewer quantity, so there is big disadvantage of the relational database to find single or a particular record.
Without any primary key attribute in the relational database it is very to find out the unique record from the table or relational database.
Without any primary key attribute the record you cannot be update.
You cannot be inserting the data without key attribute.
You cannot be deleting the data without using key attribute.
It is not possible manipulate the record without any key attribute or their record’s attribute.
Without user identity and password of the relational database you cannot access the database application.

disadvantage of the granted permission in database

If you applying granted permission on the primary database in the database application first you have to revoke the permission which has granted on the database that is generally uses in the database processing for application.

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 ...
