EFFICIENTLY HANDLING LARGE DATA SETS ON MOBILE DEVICES

摘要

A system, method, and computer program product are provided for efficiently fetching and displaying large datasets on mobile devices, such as devices running the iPhoneTM operating system. The method fetches data for a mobile device from a server and displays a plurality of data rows in a ListView within a user interface on the mobile device. The method stores primary keys on the mobile device until their corresponding data rows are to be displayed. The method reacts to user inputs such as scrolling actions and touch screen gestures to efficiently fetch and display list view subsets of large datasets. The method facilitates quick response times when navigating through large lists of data on a mobile device by: fetching displayable or visible rows of data in a data list view, preloading the visible rows on the mobile device; and binding the visible rows to user interface elements on the mobile device.
