Abstract:
Maintaining large scale healthcare information systems poses significant challenges due to their evolving complexity and sparse documentation. This paper presents a methodology and supporting tool for exploring and understanding extensive data models, motivated by and applied on the Wise Antimicrobial Stewardship Support System (WASPSS) application, an antimicrobial stewardship support system in production across several Spanish hospitals. The proposed tool enables incremental, interactive visualization of the Java Persistence API (JPA) based domain model in WASPSS, including inheritance and relationships, facilitating maintenance and onboarding. Key features include partial view saving, entity tagging, and dynamic inheritance propagation. An evaluation based on the Technology Acceptance Model (TAM) confirms the tool's perceived usefulness and ease of use among software professionals, supporting its applicability in real world maintenance workflows and its potential reuse in other healthcare contexts.
