Hospitals struggle with scattered patient data across multiple databases. This study presents an object-oriented solution for unified database access, reducing programming waste and improving application development.

Area of Science:

  • Computer Science
  • Database Management
  • Software Engineering

Background:

  • Hospitals collect vast patient data across disparate databases.
  • Integrating multiple data sources requires significant, repetitive programming effort.
  • Consolidating all data into a single database is often impractical due to security and administrative concerns.

Purpose of the Study:

  • To address the challenge of managing diverse hospital database systems within applications.
  • To propose a unified approach for accessing multiple data sources efficiently.
  • To reduce programming overhead associated with data integration.

Main Methods:

  • Utilized object-oriented programming techniques to identify commonalities among database management systems.
  • Developed a uniform communication method for applications to interact with various databases.

  • Implemented the solution using C++.

    • Main Results:

    • A C++-based system was developed to manage access to multiple database systems.
    • The approach provides a standardized interface for application-database communication.
    • Reduced the complexity and effort required for data integration in healthcare applications.

    Conclusions:

    • Object-oriented techniques offer an effective solution for unifying access to distributed hospital databases.
    • The proposed method streamlines application development by abstracting database complexities.
    • This approach enhances efficiency and maintainability in healthcare information systems.
