Offline Defaulting Service for Data Object Fields
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing software applications fail to provide default values for data object fields in offline mode, requiring users to resubmit previously entered information when switching from online to offline usage, disrupting the consistency of user interface experiences.
Innovation Solution
A system that receives default group mappings and field mappings on a client device, allowing it to set default values for data object fields locally when offline, and synchronizes changes back to the server when reconnecting, ensuring consistent default selections across all connection modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the application uses online mode to provide default values for data object fields, then the default values can be retrieved from the server, but the application cannot provide default values when offline, requiring users to resubmit information
Solution Approach 1:
The application performs preliminary actions by storing default value mappings and field configurations in a local repository before offline mode is activated. This allows the offline defaulting service to retrieve and apply default values without requiring server connection, thus resolving the contradiction between reliable default value provision and offline adaptability
Solution Approach 2:
An offline defaulting service is introduced as an intermediary component that bridges the gap between online server-based default value provision and offline local operation. This service interceptors field value requests, checks the local repository for cached mappings, and provides appropriate default values without direct server interaction, enabling both reliability and offline capability
2Stability of the object's composition
If the application requires users to resubmit previously entered information when switching from online to offline mode, then data consistency can be maintained, but user convenience and interface consistency deteriorate
Solution Approach 1:
The application creates copies of essential default value mappings and field configurations from the server and stores them in a local repository. This copying mechanism allows the offline defaulting service to replicate server-side default value behavior locally, maintaining data consistency while eliminating the need for users to resubmit information, thus improving ease of operation without sacrificing data stability
Solution Approach 2:
Default values and field mappings are preliminarily cached in the local repository before offline mode begins. This preliminary action ensures that when users switch to offline mode, the copied data structures are already available locally, allowing the application to maintain interface consistency and user convenience while preserving data consistency through the use of pre-cached mappings

AI summary
The present disclosure involves systems, software, and computer implemented methods for providing default values for fields of data objects in an offline mode. One example method includes receiving, at a client device, a default group mapping that includes a default group identifier and a default value to be used as an initial value for a field. A field mapping can be received that includes a default group identifier and a field identifier. A request can be received while the client device is offline to create an instance of an object. A determination can be made that the field mapping includes a field identifier for a field of the object. A default value can be retrieved, from a local repository on the client device. A field value of the field in a created instance of the data object can be set to be the default value.
