Object Oriented Database Model Intricacies?

OBJECT ORIENTED DATABASE MODEL


 Object Oriented Database Model: Object-oriented programming is basically divided into two phases: object-oriented analysis and object-oriented design. In the analysis phase, according to the type of problem described in the system, the main problem is divided into several small units or objects, and connections are established based on the results obtained from them. And in the design phase, by reviewing the classes or objects declared in the analysis phase, the classes, member functions and driver programs are designed by determining the class dependency, class hierarchical.


Steps of Object Oriented Analysis:


(i) Analyzing and understanding the main problem.

(ii) Describing user needs.

(iii) Dividing the original problem into smaller parts or objects as required.

(iv) Determining the properties of objects.

(v) Determining the desired results from the objects.

(vi) Making connections between objects based on desired and achieved results.


Steps of Object Oriented Design:

 (i) Review of classes and objects declared in the analysis phase,

(ii) determination of class dependencies,

(iii) class hierarchical organization,

(iv) Class Design,

(v) Member function design,

(vi) Driver Design,

(vii) Program testing and debugging

(viii) Implementation and

(ix) Maintenance.


Types of Object Oriented Language

Object-based programming is a programming paradigm that primarily supports encapsulation identity. Add is an object oriented programming language. Features of Object Based Programming Language:


(i) Data Encapsulation

(ii) Data Hiding & Access Mechanism

(iii) Automatic Initialization & Clear Up of Object

(iv) Operator Overloading.


Object Oriented Programming Language: All the programming languages ​​that provide an opportunity to write in an object oriented method and support various features of this method are called object oriented programming languages.


Object oriented programming languages ​​are-

(i) C++

(ii) Python 

(iii) Turbo Pascal

 (iv) Hyper talk

(v) Java

(vi) Visual Basic

(vii) Visual, FoxPro,

(viii) PHP etc.


Advantages of Object Oriented Database Model--

The advantages of object oriented programming are as follows: Object oriented programming languages ​​are widely used nowadays. Various features of object oriented programming can make any program easier and simpler.

The advantages of object oriented programming model are-

(i) There is no alternative to object-oriented programming languages ​​in designing real-world systems. Because in the light of reality it is possible to solve any problem very easily.

(ii) It involves dividing a large problem into smaller parts and putting the parts together to solve the problem. As a result, it is easy to detect errors.

(iii) Security of program data can be protected through data hiding.

(iv) New classes can be created by extending the scope of old classes by applying Inherited system.

(v) Additional data or functions may be added to the program at any time as required. This does not require changing the entire program.

 (vi) According to the type of problem this programming creates its own data type and any number of objects can be used in it.

 (vii) Objects of more than one data type can be used in the same program if necessary and the same object can be used in different ways.

(viii) Programs can be designed in multiple program systems using the same program.

(ix) It facilitates networking programs.

(x) Program testing and debugging is easy, so program complexity is reduced.

(xi) Program maintenance, modification, enhancement, modification are easy in this method even if the size of the program increases.


Uses of Object Oriented Programming:

(i) In case of real time system design

(iii) In object oriented databases

(v) Artificial Buddha

(vii) In compiler design

(ix) In distributed system design

(xi) Software design and analysis etc.

(ii) In simulation and modeling systems

(iv) On Hypertext, Hypermedia and Expert Systems 

(vi) On Neural Networks and Parallel Programming

(viii) In communication system design

(x) Decision support and office automation systems
