A logical data model is a high-level representation of the data elements, their relationships, and constraints in a business domain. It focuses on the entities, attributes, and relationships between them, without considering the physical implementation. On the other hand, a relational data model is a specific implementation of a logical data model using tables, columns, and foreign key relationships in a relational database management system (RDBMS). While a logical data model is technology-agnostic and focuses on the business perspective, a relational data model is specific to the implementation in a relational database system. **
