see BABOK Techniques 10.15 Data Modelling Logical data model: This model is an abstraction of the conceptual data model that incorporates rules of normalization to manage data integrity and relationships formally. It describes the structure and relationships of data in a more detailed and structured manner than the conceptual model but does not include the implementation specifics of the physical data model. So, the correct statement about a logical database model is A. An abstraction of the conceptual data model that includes rules of normalization. This matches the description provided in the BABOK guide, where the logical data model serves as an intermediate step between the conceptual and physical models, focusing on data structure and integrity.
