Database Links: Connecting Data Across Distributed Systems

What are database links in the reference of distributed system or distributed database technology? Database is a file that can be linked from the tables and their attributes included in the table. The database links provide the connection of data sharing to each other in the distributed system or distributed database models. The database links allow access to the information and retrieved from the database linked from the tables of other database files. The user can access information from single or multiple through query performance which is possible through the database links. This database link provides information according to the user’s locations to access their information quickly because the website is based on a distributed database model to provide data access from nearby and the user performs the query from the nearby server to the database. In the context of distributed systems or distributed database technology, database links are connections that allow a database to commun...

What are the disadvantages or drawbacks of the Object oriented database management system [OODBMS]?

What are the disadvantages or drawbacks of the Object oriented database management system [OODBMS]?

Drawbacks or disadvantages of the object oriented database management system

  • OODBMS is hard to create in their structure.
  • In this database without inheritance characters you will not able to create the object oriented database.
  • It is very heavy database.
  • It used only for very complex project.
  • It is also used for major application project not minor application development.
  • Generally the object oriented databases are required for system software development.

Let's discuss these points listed above about the object oriented database management system with drawbacks or disadvantages following below here:


OODBMS is hard to create in their structure:-

OODBMS is a complex database which includes the object which is a real life based object that can be designed or created with their attributes and is very complex to develop.

The object can be defined through the class and described with their properties or attributes of the objects.

Such as:- an object has 2d shape and their coordinates are (3,4), (2,3) and (5,4). These coordinates are based on the X and Y axis of graphs that need to be displayed on the computer graphics. In the details of the object the 2d shapes object is a triangle shape of object that lies on these coordinates of x and y graphs.



OODBMS is hard to create in their structure,disadvantages or drawbacks of Object oriented database management system,Disadvantage of object-oriented data model, object-oriented database example,object oriented database example in dbms,object-oriented database management system

These details of the object describe the shapes according to the graph at the values of coordinates which is a complex to design and describes at an atomic level of values.


In this database without inheritance characters you will not able to create the object oriented database:-

Without the characters of inheritance the user cannot be able to create object oriented database models for specific projects.

Without inheritance characters the fundamental principles of object oriented programming cannot support it. Hence, the object oriented database model cannot be developed and it is impossible to develop the object oriented DBMS for specific projects.

Without inheritance characters there is no way to apply the inheritance concept which means the characters are important for the inheritance concept of object oriented database management system to apply on it.

Inheritance characters are important because it is a part that allows one to apply the property on the object defined in the object database model for using the inheritance concept on the object, Name, size, shape name, color, category of model, model number etc. These are the inheritance characters that are important for inheritance concepts applied on the oops in object oriented database models.



Can object database models be easy to use?

No, the object database model is only used for complex application software development.
The object database model is used to process the real life object, classes and its properties or attributes of the object in the object database model.
Such as:- an object has so many types of properties.

For example:- a tennis ball has two categories which means two classes long tennis and table tennis.
Class: long tennis
Class: table tennis
Object: ball
Size of long Tennis ball: heavier than table tennis
There are so many types of properties that are difficult to describe but can be properly described with complex information about the object in the Object database file.

About the memory and its Classification of the computer Memory

"Hi everyone, I'm Rudra, a CS engineer and passionate blogger. Welcome to my post on [About the memory and its Classification of the computer Memory. ], where I'll share insights on Information Technology and Computer Science education. My goal is to provide helpful information and answer your questions. Feel free to ask me anything in the comments below. Let's dive into today's topic…🙂” 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 s...

Describe the different ways of mobile communication systems for users?

Describe the different ways of mobile communication systems for users? Mobile communication makes it easy to connect with many users through the different types of ways to provide the communication system, share the information to each other and make communication between two or more users through the mobile devices. Such as:- an internet service provides many ways to connect the users in the text, audio, image and video file or data connections sharing the information to each other using these data types to communicate to each other. The user needs to communicate with the other user on the data communication system application software provide the process the data to send the file or message to the user who is connected to the communication application software through their user ID name or email to communicate to share the text or audio file or video file or image file also can be shared into the application software to the user such as:- if the application software provide the chatt...
