Keith Andrews, Thomas Traunmüller, Thomas Wolkinger, Robert Gutounig, Julian Ausserhofer · 2015
Statistical open data is usually provided only in the form of spreadsheets or CSV files, which can sometimes be very large. The writer of an open data app is confronted with two choices: restrict themselves to managable bite-sized chunks of data, which can be consumed (read, parsed, and held in memory) in one go, or install and maintain their own data server which the app can query on demand.
