3. 3 The app should work offline “ ”
4. 4 “The app should work offline” means: • Equipment List; • Floor layout; • Maintenance history; • Maintenance Plan; • Work Order; • User data; • …
5. 5 • Collaborative Database of Events; • SaaS • Public and Private events; • But …
6. 6 • Collaborative Database of Events; • SaaS • Public and Private events; • But … We don’t want others to have access to our private events.
7. 7 How to solve this issue? • Let them run their own instances • The main goal of the project is having a collaborative database of events • Synchronize Databases via XDCR (Federation); • Compromises the scalability of the project, if 200 companies are using it, I will need to allow my database to replicate to all of them. • Store private events locally and public events remotely • A lot of extra coding and complexity. It can also limit some features like reports.
11. 11 Sync Gateway Synchronization • Synchronize data between Couchbase Lite and Couchbase Server • REST, Stream, Batch, and Event APIs • Pluggable authentication • Fine grained user/role-based access control • Elastically scalable in real-time
12. 12 Lightweight embedded NoSQL database with full CRUD and query functionality. Secure web gateway with synchronization, REST, stream, batch and event APIs for accessing and synchronizing data over the web. Highly scalable, highly available, high performance NoSQL database server. Built-in enterprise level security throughout the entire stack includes user authentication, user and role based data access control (RBAC), secure transport (TLS), and 256-bit AES full database encryption.
