Offline Processing System for Web Application Data Persistence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing web-based applications fail to allow users to continue interacting when network connectivity is lost, leading to data loss and inability to navigate between pages until the connection is restored.
Innovation Solution
An offline processing system that redirects and stores network communications, allowing users to continue working as if submissions were successful, and automatically posts data when the connection is re-established, using a client-side computing device to simulate an online state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system requires continuous network connectivity for web-based application operations, then data submission and server communication are ensured, but user productivity and system availability deteriorate during network outages
Solution Approach 1:
The system performs preliminary actions by storing submission data locally in a data store before network submission is attempted. When the network is unavailable, the data is already prepared and waiting in the local storage, allowing the system to maintain availability and prevent data loss. This preliminary local storage action resolves the contradiction by ensuring data is preserved regardless of network status.
Solution Approach 2:
The patent introduces a local data store as an intermediary between the user interface and the network connection. This intermediary component buffers data submissions, allowing the system to accept user input locally even when the network is down, and then forward the data when connectivity is restored. This intermediary resolves the contradiction by decoupling user productivity from network availability.
2Loss of information
If the system stores submission data locally during network outages, then data loss is prevented, but system complexity increases due to offline processing requirements
Solution Approach 1:
The patent extracts the data storage function from the network-dependent submission process and places it in a separate local data store. This extraction allows the system to handle data submissions independently of network availability, preventing data loss while keeping the complexity isolated to a specific component rather than permeating the entire system.
Solution Approach 2:
The system creates a local copy of the submission data in the data store, separate from the original network communication process. This copying mechanism allows the system to preserve data locally without fundamentally altering the network submission workflow, thus preventing data loss while minimizing the increase in system complexity.
3Ease of operation
If the system allows local page navigation without server communication, then user experience is maintained during outages, but network reconnection and data synchronization become more complex
Solution Approach 1:
The system enables self-service local page navigation by storing navigation data locally in the data store. Users can navigate between pages using locally stored information without requiring real-time server communication, maintaining ease of operation during outages. The synchronization complexity is managed by the automatic detection and resolution mechanism when the network is restored.
Solution Approach 2:
The patent implements a feedback mechanism that monitors network availability and automatically triggers data synchronization when the network is restored. This feedback loop allows the system to maintain simple local operation during outages while automatically handling the complexity of synchronization only when necessary, thus improving user experience without permanently increasing operational complexity.
Data Source
AI summary
Systems, methodologies, media, and other embodiments associated with offline processing are described. One exemplary system embodiment can include a link detection logic configured to determine a link status of the network connection where the link status includes an online state and an offline state. An offline logic can be configured to allow the application to continue operating when the network connection is in the offline state by redirecting network communications sent from the application and storing the network communications in a post data store. The offline logic can be configured to submit the network communications from the post data store to the remote device when the link status changes to the online state.
