What are data models in dbms?
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.
Which data structure used in database?

What is the definition of an object and how is it used in programming languages?
An object in programming is a data structure that contains both data and functions. It is used to represent real-world entities or concepts in a program, allowing for more organized and modular code. Objects can interact with each other through methods and properties, making it easier to manage and manipulate data in a program.
What is the main purpose of the structure?
To arrange data in a particular manner.these manner or set of rules is defined in the data structure so that the data used in computer systems can properly used at necessary time.
What are the goals of data structure?
To arrange data in a particular manner.these manner or set of rules is defined in the data structure so that the data used in computer systems can properly used at necessary time.
What's an object and how is it used in programming?
An object in programming is a data structure that contains both data and functions. It is used to represent real-world entities or concepts in a program, allowing for more organized and modular code. Objects can interact with each other through their functions, enabling the creation of complex systems and applications.
