Which type of logical database model treats data as if stored in two-dimensional tables?

The relational database management system (RDBMS) treats data as if it is stored in two-dimensional tables, which consist of rows and columns. This table format is fundamental to how RDBMS organizes and manages data, making it easy to understand and use. Each table represents a different entity, while the rows correspond to individual records, and the columns represent the attributes of those records. Additionally, relationships between tables can be established using primary and foreign keys, which facilitates complex querying and data manipulation using structured query language (SQL). This structure allows users to perform operations like insertion, updating, and deletion of data efficiently while maintaining data integrity and reducing redundancy. The relational model's reliance on set theory and first-order logic provides a robust foundation for querying and managing data effectively in various applications.
