A mid-sized hоspitаl system is prepаring tо implement а new electrоnic health record (EHR) system. The leadership team first wants to identify how the database can support their business goals, such as improving patient care and streamlining billing. At this stage, they are not yet concerned with specific tables, data types, or technologies. What type of data modeling are they working on? Options: A. Physical data modeling B. Logical data modeling C. Conceptual data modeling D. Schema deployment Answer: Conceptual data modeling Explanation:The hospital leaders are starting with broad business goals (patient care, billing) without worrying about technology or table details. This aligns with conceptual data modeling, which focuses on business concepts and goals. Logical modeling would add more detail (entities, attributes, relationships), while physical modeling specifies actual tables, keys, and database technologies. A schema is the visual blueprint, but it’s not a stage of modeling itself.
