摘 要本文主要讲述了一个船舶柴油机数据库的开发与设计过程，包括对柴油机数据（型号、各项参数）的系统分析、需求分析、数据模型图即 E-R 图的设计选用、表 结构（包括表中字段、规则等）的确定、数据库功能模块的程序编写和实现及最后 的应用系统集成与发布。84405

首先，目前比较常见的数据库有三种：ACCESS , SQL Server 和 Oracle。本次 数据库的开发与设计主要便是以 Visual FoxPro 6。0 为平台的，其主要过程都是基于 SQL 语言的一种设计。在本文中，将会详细阐述依据 Visual FoxPro6。0 所完成的项 目数据库表的创建、视图的创建查询以及功能模块的实现。

其次，在本文中将会简单介绍一下船舶柴油机的分类及型号说明，以方便对各 项参数有一个较为深刻的理解，从而能对柴油机数据的系统分析、需求分析进一步 完善。

最后简述一下本次数据库所需要实现的功能，其包括所建立数据库软件的密码 登陆退出、对船舶柴油机型号及对应各项参数（功率、转速、缸径、冲程等等）的 上下页浏览、查询以及一个能实现各条件查询筛选的子模块。

最终，在通过本次毕业后，将会建立起一个现阶段下相对完善、功能较为齐全 的一个简单的船舶柴油机数据管理系统。

Abstract This article mainly tells the process of development and design of marine diesel engine 。 The process includes the date(model,parameter) analysis of the system of diesel engine,demand analysis,the design and selection of the data model figure-E-R figure,the determination of form structure(include field and rules,etc) the programming of data function module and finally the integration and release of the system of application。

Firstly,at present there are three common kinds of database:ACCESS,SQL Server and Oracle。The development and design of the database is mainly based on Visual FoxPro 6。0 as a platform,and the main process is a kind of design which is based on SQL language。This article will elaborate the creation of the project,the datebase and the form,the creation and query of the view,and the realization of function module which are completed by Visual FoxPro 6。0。

Secondly,this article will introduce the working principle and the working area of marine diesel engine in order to develop a deeper understanding of the various parameters。In this,we can achieve further perfect with system analysis and requirement analysis of diesel engine。

Finally,we will briefly describes the function which need to be implemented in the database,that include password,log in and out of database software that have been established,browse and query of the models and various parameters of marine diesel engine,and a query filter which can realize all kinds of conditions of sub module。

In the end, through this graduation design, we will establish a simple management system of data of marine diesel engine, which is relatively perfect and whose fuction is more complete at this stage。

Keywords: marine diesel engine; database; development and design; writing program; function implementation; management system。
