摘要

公司规模的不断扩大令行政部的管理工作日益繁重，所以其迫切需要开发一个MIS(Management Information System)系统来使其行政管理规范化、制度化、所需各种数据标准化。在大型系统的开发过程中，使用Hibernate作为业务逻辑层和数据库层之间的持久层，实现对象到关系数据库的持久存储，不但解决了对象模型与关系模型之间的“阻抗不匹配”问题，也提高了项目开发的效率。所以，某公司决定开发基于Hibernate技术的Equipment Management System。
Hibernate是目前最流行的开源对象关系映射框架，是面向对象的程序设计语言和关系数据库之间的桥梁。它对JDBC作了轻量级的封装，不仅提供ORM映射服务，还提供数据查询和数据缓存功能。作为优秀的持久层框架实现，Hibernate提供了强大、高性能的对象到关系数据库的持久化服务，其良好的持久层映射机制，使得操作完全面向对象。
本文研究了Hibernate技术，分析了Hibernate的对象关系映射框架实现机制及其工作原理。最后，结合实践，介绍了基于Hibernate技术的Equipment Management System的开发。

Hibernate –Based
Equipment Management System Development

Abstract
With the company expanding the scale, the workload of Administration Department is increasing. So their urgent need is to develop a MIS (Management Information System), which makes the administration to be standardization and institutionalization. In the process of large systems development, it uses Hibernate between business logic layer and database layer as the persistence layer, implementing the persistent store from objects to relationship database. It solves the impedance mismatch difficulties between the object model and the relationship model, and improves the efficiency of the project development. Therefore, the company decides to develop Equipment Management System of Hibernate-based.
Hibernate is the most popular open source object-relational mapping framework, and also a bridge between the object-oriented programming language and the relational database. It makes JDBC a lightweight package. And, it not only provides ORM mapping services, but also provides data query and data cache function. As a good framework for achieving persistence layer, Hibernate provides a powerful， high-performance persistence service from objects to the relational database. Its good mechanism for persistence mapping makes operations object-oriented fully.
In this paper, some research has been done on the Hibernate technology, and also analysis object-relational mapping framework for the realizing mechanism of the Hibernate and its working principles. Finally, according to practices, it introduces the development of Equipment Management System, which is based on Hibernate technology.
