In this article, you will see how to create a generic data access layer (DAL) in a WCF project. b. We'll build on the Abstract DAO class we saw in our previous articleon Spring and Hibernate, and add generics support. The modules may also be grouped together to provide better functionalities in a Web application. In this course, Spring Framework: Overview of Spring Data, you'll learn about how Spring Data can be used to make data access easier. Spring Data JPA is a method to implement JPA repositories to add the data access layer in applications easily. This article will focus on simplifying the DAO layerby using a single, generified Data Access Object for all entities in the system, which will result in elegant data access, with no unnecessary clutter or verbosity. In this blog, we will create data access layer using Entity Framework Code First Approach. The repository's whole point is to define a contract that your data access layer will implement. Dynamic query derivation from repository method names Spring Web Flow, and Spring Web MVC. In this part of the Spring architecture, we are going to discuss OXM, JMS, ORM, Transaction Modules, and JDBC.
