摘要

公司規(guī)模的不斷擴(kuò)大令行政部的管理工作日益繁重，所以其迫切需要開(kāi)發(fā)一個(gè)MIS(Management Information System)系統(tǒng)來(lái)使其行政管理規(guī)范化、制度化、所需各種數(shù)據(jù)標(biāo)準(zhǔn)化。在大型系統(tǒng)的開(kāi)發(fā)過(guò)程中，使用Hibernate作為業(yè)務(wù)邏輯層和數(shù)據(jù)庫(kù)層之間的持久層，實(shí)現(xiàn)對(duì)象到關(guān)系數(shù)據(jù)庫(kù)的持久存儲(chǔ)，不但解決了對(duì)象模型與關(guān)系模型之間的“阻抗不匹配”問(wèn)題，也提高了項(xiàng)目開(kāi)發(fā)的效率。所以，某公司決定開(kāi)發(fā)基于Hibernate技術(shù)的Equipment Management System。

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.

Key Words: Hibernate, Persistence, Object Relation Mapping
