A Web‐Based Query Interface for Health‐Care Data Warehouses

This paper presents a new type of computer interface to large population health-care data repositories via the Internet. It does not require programming knowledge but is flexible enough to handle the ad-hoc queries common in research settings. The interface allows for the automated creation of SAS programs by the end users using a GUI-based questionnaire. The interface is the front end of a three-tier client/server system for on-line information retrieval for large health-care data warehouses.
