All Known Implementing Classes:

DefaultReactiveDataAccessStrategy
```
public interface ReactiveDataAccessStrategy
```
Data access strategy that generalizes convenience operations using mapped entities. Typically used internally by DatabaseClient and repository support. SQL creation is limited to single-table operations and single-column primary keys.
