Microcomputer-assisted filing system of cardiac catheterization records using a relational database management system

Area of Science:

• Medical Informatics
• Database Management Systems

Background:

• Efficient storage and retrieval of cardiac catheterization records are crucial for clinical practice and research.
• Existing methods may lack flexibility and ease of use for managing large datasets.

Purpose of the Study:

• To develop a computer-assisted database system for efficient management of cardiac catheterization records.
• To leverage a relational database management system for enhanced data handling capabilities.

Main Methods:

• A 16-bit microcomputer system with dual floppy disk drives, 20 MB RAM, and a hard disk drive was utilized.
• Programming was performed using R:base 5000, a relational database management system.
• Data inquiry procedures included direct commands and preprogrammed command files.

Main Results:

• The system allows for easy and rapid database creation and modification.
• Flexible data retrieval based on various criteria is achievable through operational commands and conditional operators.
• Relational capabilities facilitate the reconstruction of new data files from existing ones.

Conclusions:

• The developed system provides efficient storage and retrieval of cardiac catheterization data.
• Key advantages include ease of use, flexibility, powerful data inquiry, and cost-effectiveness.
• The system enhances the potential for data analysis and reconstruction in cardiology.
