Accessing data using R2DBC

R2DBC ("Reactive Relational Database Connectivity") is a community-driven specification aimed at standardizing access to SQL databases with using reactive templates.

Package hierarchy

The R2DBC abstraction structure in the Spring Framework consists of two different packages:

• core: The org.springframework.r2dbc.core package contains the DatabaseClient class and many related classes. See "Using R2DBC Core Classes to Manage Basic R2DBC and Error Handling".

• connection: The org.springframework.r2dbc.connection package contains a helper class to provide easy access to ConnectionFactory and various simple ConnectionFactory implementations which can be used to test and run unmodified R2DBC.
