Object oriented means the internal structures used in an application represent the real world 'objects'. This means the application you are creating is using a model that is closer to the real world and that is always an advantage. The biggest advantage may be in the form of easy maintenance as the application evolves.
two main early navigational data models were the hierarchical model and the CODASYL model (network model)
Advantages and Disadvantages of primary data are: Advantages 1. Data is basic 2. Unbiased information 3. Original data 4. Data from the primary market/ population 5. Data direct from the population. Disadvantages. 1. Large volume of data. 2. Huge volume of population. 3. Time consuming 4. Direct and personal intervention has to be there. 5. Raw data.

Three ways of organizing data are through hierarchical structure, where data is organized in a tree-like format with parent and child relationships; relational databases, where data is stored in tables with relationships established through keys; and object-oriented databases, where data is organized as objects with attributes and methods. Each method has its own advantages and is used based on the specific requirements of the data and the system in which it will be stored and accessed.

advantages of object oriented data base
Object-oriented programming is a feature in C++ that allows you to better model real-world objects. An object is an instance of a class, which is a data structure in C++ that allows you to group different, but related types of data together.
The advantages are Data Encapsulation Data Hiding Easy to maintain the code Reuseability of classes And disadvantages are wastage of time in case of small projects or codes
A data model is a collection of concepts that can be used to describe the structure of a database and provides the necessary means to achieve this abstraction whereas structure of a database means the data types,relationships and constraints that should hold on the data. Data model are divided into three different groups they are 1)object based logical model 2)record based logical models 3)physical models Types: Entity-Relationship (E-R) Data Model Object-Oriented Data Model Physical Data Model functional data model
The purpose of constructor in object oriented programming is to initialize data. Likewise copy constructors are used to initialize an object with data from another object.
Data-Oriented Programming (DOP) focuses on decreasing the complexity of the Object-Oriented Programming (OOP) application systems by rethinking data
This breaks the problem in terms of objects. It is different from functional approach, as it binds the data and the operations that can be performed on data in a unit. By doing this it promotes encaptulation.
No, object-oriented databases do not store data in tables like relational databases. Instead, they store data as objects that have attributes and methods associated with them. Objects in an object-oriented database can also have relationships with other objects, making it a more flexible way to store and access data.
Before Object oriented programming the term which was used was “Structural Programming” where a programmer has to use the predefined data types, they cannot define their own data type. But when the term object oriented programming start in programming programmer become able to define its own data type according to their own use. Here a coder can define its own data types called classes and then create object from these classes. Coding in Object Oriented language Advantages of Object Oriented Programming One of the main advantages of OOP over procedural programming techniques is that they enable programmers to create modules that do not need to be changed when a new type of object is added. A programmer simply can create a new object that inherits from existing objects many of its features . This makes object-oriented programs easier for programmer to modify.
An object-oriented database (OODB) is a type of database that stores data in objects rather than in tables, making it easier to represent complex relationships and hierarchies in data. OODBs are designed to work well with object-oriented programming languages and frameworks.
No. C is not object-oriented, it is a procedural language.C++, while object-oriented, is not purelyobject-oriented. One of the requirements for a pure object-oriented language is that everything is an object. C++ still has primitive data types (int, long, double, etc.), and so is not purely object-oriented.
