Database concepts

There are two interfaces for handling database changes:

• EntityDb
• RxDb (for Java)

The key read (get, getRange, etc), write (insert, upsert, etc) and subscribe (subscribe, bulkSubscribe) operations for these interfaces are described in detail in the relevant sections:

• EntityDb read operations
• EntityDb write operations
• RxDb read operations
• RxDb write operations
• Subscribe

This section looks at one other database concept:

• Optimistic Concurrency
