As an integral part of the IFH Survey Data-Core, we will leverage a unique JAVA based web-application developed specifically for conducting multilingual, in-person research with difficult-to-reach populations, which allows for flexible data collection, monitoring, and storage to adhere to regulatory standards and best practices. Our survey data collection system has been rigorously field-tested and implemented to collect data with thousands of participants around the world. Data collection is most reliable when conducted in-person, and today, most survey research and field in-person data collection rely on either manual input or third-party systems which are inflexible, time consuming, and less secure.
Our platform utilizes a Struts web framework, Spring application framework, and Hibernate database ORM framework, with an SQL back-end database to provide these five primary, innovative benefits.
