The most commonly used database in healthcare is the relational database model. Relational databases organize data into tables with predefined relationships, allowing for efficient storage and retrieval of structured data. This model is well-suited for managing patient health records, clinical data, administrative information, and other healthcare-related data. Relational databases offer flexibility, scalability, and support for complex queries, ensuring data integrity and consistency. SQL (Structured Query Language) is commonly used to interact with relational databases, enabling data manipulation and retrieval. Many healthcare organizations utilize relational databases, such as Oracle Database, Microsoft SQL Server, MySQL, or PostgreSQL, as the foundation for managing their healthcare data. These databases provide a solid framework for secure and efficient storage of patient information, supporting critical healthcare operations and decision-making processes. Specialized healthcare software solutions, like the Drlogy Clinic Software, leverage relational databases to effectively manage and secure patient data, streamline workflows, and facilitate interoperability among healthcare providers.
