    Design Patterns used in Hibernate Framework

    Image
    In this post, let's discuss a different kind of design patterns which are widely used in the Hibernate Framework. Design Patterns denote the best computer programming practices in the object-oriented software development. Hibernate framework has been built by using the following design pattern or standard practices. I list few known design patterns used in Hibernate Framework. Please mention in a comment, if you know any other design patterns used in Hibernate Framework. You can also read my post of  Design Patterns used in Spring Framework Domain Model Pattern The domain model is treated as POJO in Hibernate. The domain model is an object model of the domain that incorporates both behavior and data.

    Value List Handler

    The  Value List Handler  provides the search and iteration functionality. To perform a search, the Value List Handler uses a  Data Access Object  to execute the query and retrieve the matching results from the database. It is hard to understand this pattern so my suggestion is to go to  source code  section and have a look at code step by step gives you more clarity. This pattern is divided into a number of sections for simplicity like problem, forces, solution etc. Problem (Problem section describes the design issues faced by the developer) You have a remote client that wants to iterate over a large results list. Forces (This section describes Lists the reasons and motivations that affect the problem and the solution. The list of forces highlights the reasons why one might choose to use the pattern and provides a justification for using the pattern) You want to avoid the overhead of using EJB finder methods for large searches. You want to implement a...
