Summary
This review introduces logic models for evaluating Web-based data query systems (WDQSs). Logic models help assess WDQS development and ensure objectives are met for improved outcomes.
Area of Science:
- Information Science
- Program Evaluation
- Web-based Systems
Background:
- Web-based data query systems (WDQSs) require robust evaluation methods.
- Traditional evaluation approaches may not fully capture the complexities of WDQS development and implementation.
Purpose of the Study:
- To present program evaluation perspectives, focusing on logic models.
- To demonstrate the applicability of logic models to the evaluation of WDQSs.
Main Methods:
- Review of program evaluation literature.
- Application of logic model framework to WDQS components (inputs, constraints, activities, outputs, outcomes).
- Identification of potential evaluation items and outcome examples for WDQSs.
Main Results:
- A logic model framework is proposed for WDQS evaluation.
- Detailed components of a WDQS logic model are outlined.
- Examples of initial, intermediate, and ultimate outcomes for WDQSs are provided.
Conclusions:
- Logic models are crucial for early WDQS development and ongoing maintenance.
- Logic models provide a roadmap to identify and rectify issues in WDQS development, implementation, and maintenance.
- Utilizing logic models enhances the probability of achieving desirable WDQS outcomes.
