Functional Dependency in DBMS

Data Models in DBMS in hindi course, in this course we will learn about the data models in Database Management Systems (DBMS), which are fundamental for organizing, storing, and managing data efficiently. Data models define the logical structure of a database and establish the relationships among data elements. We will explore various types of data models, each suited for different types of applications and requirements. We will begin with the Hierarchical Data Model, which organizes data in a tree-like structure, where each child node has a single parent node, suitable for applications requiring a clear, parent-child relationship. Next, we will delve into the Network Data Model, which allows more complex many-to-many relationships through a graph structure. The Relational Data Model is a cornerstone of modern databases, organizing data into tables (relations) with rows and columns, and using primary and foreign keys to establish relationships. The Entity-Relationship (ER) Model will be covered to help in designing relational databases by visually mapping out entities and their relationships. We will also examine the Object-Oriented Data Model, which integrates object-oriented programming principles to handle complex data and relationships more naturally. The Object-Relational Data Model combines the relational model with object-oriented features to offer greater flexibility.
