About This Architecture

Conceptual Entity-Relationship model for a medical clinic system with four core entities: Medico, Paciente, Consulta, and Convenio. Medicos maintain many-to-many relationships with Convenios through an associative entity, while each Medico conducts one-to-many Consultas with Pacientes. The schema captures essential attributes including physician credentials (cod_medico, especialidade, dt_admissao), patient demographics, consultation details (descricao, diagnostico, medicacao), and insurance provider information. This ER diagram demonstrates proper normalization for healthcare data, supporting queries across physician specialties, insurance networks, and patient consultation history. Fork and customize this template on Diagrams.so to extend it with additional entities like Prescricao, Internacao, or Laboratorio.
