We have so far explored Spring Framework's comprehensive coverage of all technical aspects around data access and transaction. Spring provides multiple convenient data access methods, which removes much of the hard work for the developer involved in building the data layer and standardizing the business components. The correct usage of Spring data access components makes the data layer of the Spring application clean and highly maintainable. Leveraging Spring Transaction support ensures the data integrity of applications without polluting the business code and makes your application portable across different server environments. Since Spring abstracts much of the technical heavy lifting, building the data layer of your applications becomes an enjoyable piece of software engineering.
