Couchbase Lite is a NoSQL mobile database that uses a document data model with key-value pairs and handles data one document at a time. It supports push and pull replication for syncing documents between devices and servers, including both continuous and one-shot replication with options for persistent or non-persistent settings. The document provides details on Couchbase Lite's data structures, basic operations, replication features, and includes links to related resources and a demo app that uses Cloudant as the backend data layer.

2. NoSql
Specifics
●
Data not modeled in tabular relations
●
Typical structures: graph, tree, key-value pairs
●
Simpler design
●
Horizontal scaling
●
Used for big data and availability applications
Drawbacks
●
Consistency
●
Lack of standardized interfaces and full ACID support
●
Use of low level query languages

3. Database mechanisms
Documents (JSON) are building blocks, handled one at
a time
●
Reading
– Key-based lookup mechanism
– Client provides the key(s range)
●
Writing
– Key-based update mechanism
– Documents are updated (low latency)
●
Push and pull replication
●
Conflict management support

7. Creating a database

8. Create, update, delete

9. Replication
●
Key feature that enables document syncing
– Pull, remote to local
– Push, local to remote
– Sync, configuration consisting of pull and push
●
Continuous replication
– Open connection, acts upon detected change
– Connectivity change aware!
– cannot get a marker on the map by an id
●
One shot replication
– Active until changes are copied
●
Persistent replications vs non-persistent
●
Filters
