Spring Data

There are multiple sources of data in today's world--SQL (relational) and a variety of NOSQL databases. Spring Data tries to provide a consistent data-access approach to all these different kinds of databases.

Spring Data provides integration with a varied range of specifications and/or data stores:

• JPA
• MongoDB
• Redis
• Solr
• Gemfire
• Apache Cassandra

Some of the important features are listed as follows:

• Provides abstractions around repository and object mappings--by determining queries from method names
• Simple Spring integration
• Integration with Spring MVC controllers
• Advanced automatic auditing features--created by, created date, last changed by, and last changed date

We will discuss Spring Data in more detail in Chapter 8, Spring Data.
