Study Notes
Offline Mobile Application Architecture
- Offline-first apps are designed to perform core functionality without internet access, ensuring a seamless user experience even in low or no connectivity scenarios.
- Essential strategies for seamless user experience include identifying essential functionality, implementing data synchronization, and storing data locally.
Best Practices for Offline Mobile Application Architecture
- Identify essential functionality to ensure a seamless user experience.
- Implement data synchronization to ensure consistency and resolve conflicts.
- Store data locally using methods like SQLite databases, key-value stores, and NoSQL databases.
Local Storage Methods
- SQLite databases: a popular choice for local data storage due to their lightweight nature and efficiency, suitable for storing structured data.
- Key-value stores: a simple and efficient way to store data as pairs of keys and values, suitable for storing small pieces of data.
- NoSQL databases: alternative to traditional relational databases, offering flexible schemas and support for complex data structures.
Security and Privacy Considerations
- Encrypt sensitive data stored locally on the device to protect it from unauthorized access.
- Implement secure data handling practices to minimize the risk of data breaches or leaks.
- Obtain explicit user consent before accessing or storing personal data on the device.
- Define clear data retention policies to govern how long data should be stored locally on the device.
- Ensure secure communication channels between the mobile application and any external services or servers.
Data Synchronization Techniques
- Push-based synchronization: local data source mirrors network data and updates server notifications.
- Pull-based synchronization: the app fetches data from the network on demand.
- Hybrid synchronization: a mix of pull and push approaches based on data type.
Conflict Resolution
- Resolving discrepancies between local and network data ensures consistency between local and network data.
- Common approaches to conflict resolution include "Last Write Wins", client wins, server wins, time-based resolver, and version control systems.
Approaches to Offline Mobile Application Architecture
- Local storage: store all necessary data locally on the device using a local database.
- Offline-first: design an app to work offline by default, with online connectivity being a secondary consideration.
- Hybrid: use a combination of local storage and online connectivity to provide the best of both worlds.
- Progressive enhancement: design an app to work offline by default but provide additional functionality when an internet connection is available.
Tools and Frameworks
- Pros: improved user experience, reliability, and reduced data usage.
- Cons: limited functionality, limited storage, conflict resolution, and increased development cycle.
When to Use Offline Mobile Application Architecture
