Data Processing in the National Health Insurance Study

Describes the important factors inherent in the data collection and processing of large surveys in general, and the particular ways they apply to the Health Insurance Study (HIS). These factors translate into data processing considerations that significantly influenced the design of the HIS data processing systems and the database. The design of the HIS database is presented and the principal data sources are identified. Additionally, the paper outlines the architecture of the HIS system and describes the component subsystems.
