Data Driven Forms Local Caching Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Web site authors face challenges in providing a consistent user experience across diverse devices, particularly due to unreliable network connections and bandwidth issues on mobile devices, which complicates the presentation of data-driven forms.
Innovation Solution
A computing system that caches data from a web server and renders multiple views, allowing for low-latency display of data-driven forms without requiring native applications or complete data downloads, by asynchronously loading additional data when the cache is full.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is loaded from a database for presentation in data driven forms, then the data can be updated regularly and presented to users, but network bandwidth is consumed and latency increases especially on mobile devices
Solution Approach 1:
The system performs preliminary actions by caching data locally on the user device before it is needed for presentation. The cache stores data elements that can be retrieved asynchronously, allowing the form to be populated without waiting for network requests during user interaction. This preliminary caching resolves the contradiction by preparing data in advance, reducing both perceived latency and network dependency.
2Ease of operation
If a stand-alone application is released for mobile devices, then the user experience can be optimized for the device, but the device must download all relied-upon data to function
Solution Approach 1:
The invention extracts only the necessary data elements from the complete dataset and stores them in a cache on the user device. Instead of requiring all data to be downloaded, the system identifies and retrieves only those data elements needed for the current form presentation. This selective extraction reduces the quantity of data downloaded while maintaining optimized user experience through local data availability.
Solution Approach 2:
The system implements partial action by loading a subset of data into the cache rather than all available data. The cache stores sufficient data elements to populate the form without requiring complete data synchronization. This partial loading approach reduces network bandwidth consumption while providing responsive form functionality.
3Productivity
If data is cached on the user device, then network communication is reduced and latency decreases, but the cache may become full requiring additional data management
Solution Approach 1:
The system implements self-service cache management where the cache automatically handles data retention and eviction without requiring complex external management. The cache stores data elements with identifiers that enable automatic matching with form data requirements. When the cache is full, the system asynchronously retrieves additional data elements without manual intervention, allowing the form rendering to proceed at high speed while the cache manages itself.
4Adaptability or versatility
If multiple views are rendered from cached data, then data can be presented in different formats without additional network requests, but the cache must store sufficient data for all views
Solution Approach 1:
The system segments data into discrete data elements that can be independently cached and retrieved. Each data element is identified by a unique identifier and can be individually stored in the cache. This segmentation allows the system to assemble different views from the same cached elements without requiring complete datasets for each view, reducing the total cached data volume while maintaining view presentation flexibility.

AI summary
Concepts and technologies are described herein for presenting data driven forms. In accordance with the concepts and technologies disclosed herein, a user device obtains a resource referencing or presenting data driven forms and obtains data displayed or used by the resource. The user device stores the data in a cache accessible by the user device. The user device can render multiple views containing data from the cache. The user device can display one of the views and hide the other views from display. If the user device detects input for viewing other views, the user device can present one of the previously hidden views. The user device also can manage the cache and download additional data, if the cache empties or is not full.
