The Researcher/Analyst’s Challenge “The researcher cannot get access to the data; if he can, he cannot read them; if he can read them, he does not know how good they are; and if he finds them good he cannot merge them with other data.” Information Technology and the Conduct of Research: The Users View National Academy Press, 1989

Data Flow Resistances These resistances can be overcome through a distributed system that catalogs and standardizes the data allowing easy access for data manipulation and analysis. ,[object Object],[object Object],[object Object],[object Object],The data flow process is hampered by a number of resistances.
