Development Scope
Scope and Basic Check
Determine the existing foundation, technical dependencies and content that needs to be developed based on the size of a single piece of data, sampling frequency, storage media, offline duration, confirmation method and data retention priority.
Implementation and integration
Design persistence queues, serial numbers, write verification, confirmation of deletion, re-transmission speed limit and capacity overflow strategies, taking into account storage life and online data.
Delivery Documentation
Deliver cache module, parameter description and network and power outage records.
Verification and Constraints
Offline recording capabilities have capacity, power supply and media boundaries, and verifiable storage duration and overflow behavior need to be given.
Project implementation process
Verification of data and interfaces → Confirmation of technical solutions and verification use cases → Implementation of integration with the target environment → Regression of abnormal scenarios → Transfer of version data.
Verify the implementation results in the target hardware and software environment, and deliver records of associated interface configurations, version dependencies, and problem handling to facilitate subsequent integration and maintenance by the enterprise R&D team.
Project Inputs
- Single data size, sampling frequency, storage medium, offline duration, confirmation method and data retention priority.
- Design information, code, interface permissions and target test equipment can be provided.
- Source files, programs or tools expected to be delivered, inter-module integration testing responsibilities and project nodes.
- Acceptance samples, environment, test conditions and passing thresholds.
Deliverables and Acceptance
| Deliverables | Delivery content | Verification method |
|---|---|---|
| achieve results | Deliver cache module, parameter description and network and power outage records. | Test data continuity during network outages. |
| Integrated data | Versions and dependencies, interface configuration, usage or deployment steps, and integration changes | Perform power-down testing during the write and acknowledge phases. |
| Verify records | Test conditions, execution records, problem lists and regression results | Verify full storage, duplicate confirmation and supplementary transmission sequence. |
The delivery scope and acceptance criteria are determined based on the target environment. Third-party SDK, licenses, laboratories, cloud resources, equipment materials and on-site support are listed separately; when the existing information is insufficient, follow-up work will be determined through interface verification or key function verification.
Frequently Asked Questions
How to estimate offline cache capacity?+
First calculate the payload based on data size, sampling frequency and offline duration, and then add indexing, verification, write management and reserved space. It is also necessary to verify the storage life and disposal strategy after the data is full.
4G What information do I need to provide first for the development of offline cache and resumable data upload?+
Please give priority to the single data size, sampling frequency, storage medium, offline duration, confirmation method and data retention priority. At the same time, the existing implementation, problems encountered, expected changes, and compatible test conditions are explained to facilitate the determination of implementation scope and reproduction methods.
Can it be implemented on existing products?+
You can first evaluate the scope of existing designs and versions that can be changed, retain the verified parts, and determine the interfaces and dependencies that need to be adjusted. This service requires attention: offline recording capabilities have capacity, power supply and media boundaries, and verifiable storage duration and overflow behavior need to be given. Existing and new functions must undergo regression testing within the agreed scope after the changes.
