2.Data organized into files and folders
3.Data organized into a hierarchical tree structure
4.Data organized into a network of interconnected nodes
Solution
The correct answer is Data organized into tables with rows and columns
Key Points
In a relational database, data is structured in tables (also called relations). Each table consists of rows (also known as records or tuples) and columns (also known as fields or attributes).
Rows: Each row in a table represents a single record or instance of data.
Columns: Each column represents a specific attribute or property of the data, with all values in a column being of the same data type.
This tabular format allows for easy data retrieval and manipulation using SQL.
Additional Information
Data organized into files and folders: This describes a file system, not a relational database.
Data organized into a hierarchical tree structure: This describes hierarchical databases, which organize data in a tree-like structure.
Data organized into a network of interconnected nodes: This describes network databases, where data is organized in a graph structure.
