A data model is a collection of concepts that can be used to describe the structure of a database.
Data models can be broadly distinguished into 3 main categories-
1)high-level or conceptual data models (based on entities & relationships)
It provides concepts that are close to the way many users perceive data.
2)lowlevel or physical data models
It provides concepts that describe the details of how data is stored in the computer.
These concepts are meant for computer specialist, not for typical end users.
3)representational or implementation data models (record-based,object-oriented)
It provide concepts that can be understood by end users. These hide some details of data storage but can be implemented on a computer system directly.

Data models in DBMS represent the logical structure of the database by defining the relationships, constraints, and properties of the data stored. They provide a way to organize and structure data for efficient storage, retrieval, and manipulation. Common types of data models include relational, hierarchical, network, and object-oriented models.

What are three types of dbms?
Three types of DBMS (Database Management Systems) include relational DBMS, object-oriented DBMS, and NoSQL DBMS. Relational DBMS organizes data into tables with rows and columns, object-oriented DBMS stores data as objects and classes, and NoSQL DBMS handles unstructured and semi-structured data with flexible schemas.
What is the difference between OODBMS and DBMS?
Object-Oriented Database Management System (OODBMS) stores data in the form of objects with attributes and methods, allowing for complex data structures and relationships. Traditional Database Management System (DBMS) stores data in structured tables with rows and columns, focusing on relational data models. OODBMS is better suited for applications with complex data structures and relationships, while DBMS is more widely used for simpler data storage and retrieval needs.
What is the fullform of DBMS?
The full form of DBMS is Database Management System.

List the characteristic of the modern DBMS?
Some characteristics of modern database management systems (DBMS) include support for relational data models, ACID-compliant transaction processing, scalability for handling large volumes of data, support for a variety of data types, and advanced security features to protect data integrity and confidentiality.
How data will store in DBMS?
Databases store data using any of the robust data structures for efficient management of data. They can use any of the record based logical models to represent the data. Hierarchical, Network or Relational data models.
What does an DBMS do?

What are three types of dbms?

How does DBMS reduce data redundancy?
DBMS stands for database management system. DBMS reduce data redundancy as it checks if the data is duplicate and if duplicate then store it as a single record.
Discuss the main categories of data models?
The main categories of data models are conceptual, logical, and physical. Conceptual data models represent high-level concepts and relationships between different data elements, focusing on understanding the business requirements. Logical data models map the conceptual model into a specific data storage technology, translating the conceptual model into a more structured format. Physical data models define how data will be stored, organized, and accessed in a specific database system, incorporating details like tables, columns, keys, and indexes.
What are rows in dbms?
In DBMS the data is stored in the form of table . Each row in DBMS is known as tuple.
What is DBMS and what r the features of Dbms?
DBMS stands for data base management system. DBMS is a collection of programs that enables users to create and maintain a database. The DBMS is a general purpose software system used to facilitate the process of defining, constructing and manipulating data bases for various applications. features of DBMS: 1.Data independence 2.Efficient data access 3.Data integrity & security 4.Data administration 5.Reduced application development time

What is data integration in dbms?
Data integration in DBMS refers to the process of combining data from different sources and formats into a unified view for analysis and decision-making. It involves mapping and transforming data to ensure compatibility and consistency across multiple systems. Data integration helps organizations make better informed decisions by providing a comprehensive and accurate view of their data assets.
What is DBMS?
