Which of the following data models is used to store data in the form of tables/relations?
Correct answer: C. Relational Model
- A. Network Model
- B. Hierarchical Model
- C. Relational Model
- D. Object Data Model
Explanation
The correct answer is (C) Relational Model.The relational model is a type of data model that stores data in tables (also called relations). These tables consist of rows and columns. Each row represents a record in the database, and each column represents an attribute (or characteristic) of that record.Here's why the other options are incorrect:(A) Network Model - The network model allows for a many-to-many relationship between data points. This means a single data point can be connected to multiple other data points, but the connections can become complex and difficult to manage.(B) Hierarchical Model - The hierarchical model organizes data in a tree-like structure, with a parent-child relationship between data points. This means a data point can have one parent, but can have many children. However, this model is not very flexible for representing complex relationships between data points.(D) Object Data Model - The object data model stores data in objects, which encapsulate both data and the procedures that operate on that data. This model is well-suited for object-oriented programming, but it can be more complex to manage than the relational model

About Databases
Databases cover tables, records, fields, keys and relationships, together with database management systems and relational database design. The subject includes primary and foreign keys, normalization, SQL commands such as SELECT, INSERT, UPDATE and DELETE, queries, forms and reports, while distinguishing a database from a spreadsheet used for simple tabular data.
