what are the main differences between relational database and object oriented database in a model designing?

What are the differences between Relational database system and Object oriented database system?

Relational database system

The relational database system depends on the rows and columns.
It is based on the table or matrix form.
It can generate by structure query language [SQL].
In this database the table is called relation.
In this database rows and columns called tuple and attribute respectively.
In commercial business field the relational database most commonly use as compare to object database.

Object oriented database system

The object database depends on the objects and classes.
It is based on the inheritance hierarchical relative structure.
It can generate by object oriented programming language C++ or JAVA.
In this database the real world entity is called object.
In this database entity and attribute are called object and class respectively.
In commercial business fields the object database rarely used as compare to relation database but the object database is best for custom design software or application development and custom database design.

What are the main differences between OODBMS and RDBMS model?

There are some major difference between object databases management system model and relational database management system model. Here are some points to remember about the difference between OODBMS and RDBMS below.

The object database is uses to stores atomic value.
It describes the atomic value with all types of attributes of their atomic value data and information.
Object database easily illustrates the integral parts of atomic value data.
ODB best describes all types of data with different attributes the data types are such as integer, float, string, character etc.

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 ...
