Summary
PRIST-2 is a new tool for rapid prototyping of clinical applications in hospital information systems. It extends relational databases with object-oriented features for better data independence and semantics.
Area of Science:
- Computer Science
- Medical Informatics
Background:
- Large-scale Hospital Information System (HIS) projects require efficient tools for rapid application prototyping.
- Existing relational database management systems (RDBMS) offer portability but lack the semantic richness for high data independence.
Purpose of the Study:
- To introduce PRIST-2, a fourth-generation interactive environment for developing clinical applications within HIS.
- To propose an extension to the relational model that incorporates object-oriented database management system (OODBMS) characteristics.
Main Methods:
- Developed PRIST-2 as an interactive prototyping environment.
- Utilized an SQL-based commercial RDBMS for system portability.
- Extended the relational model with OODBMS concepts like "types" and "encapsulation".
Main Results:
- PRIST-2 facilitates rapid prototyping of clinical applications.
- The proposed extension enhances relational databases with object-oriented features.
- Improved data independence and application semantics are achieved.
Conclusions:
- PRIST-2 offers a robust solution for clinical application development in large HIS.
- The hybrid relational-object model addresses limitations of traditional RDBMS.
- This approach enhances data management and application development in healthcare settings.
