【摘要】 资源加工与生物工程学术信息服务系统是一个为资源加工与生物工程学术领域进行服务的信息系统。对学术信息服务系统而言,共享是交流的基础,交流是服务的保障,学术信息服务需要建立在一个平台之上。本论文的目标,在于满足用户的当前需求与未来的潜在需求,规划、设计并开发一个用于资源加工与生物工程学术领域的学术信息服务系统,以期为该领域的学术、科研、生产实践、产业融资等需求提供服务。本系统首先采用传统的结构化开发方法,将系统分为前台和后台两大系统从而实现大系统的“分而治之”;然后,在架构设计和开发过程中,结合现代的面向对象(Object_Oriented)的思想以及基于WEB的应用技术,采用三层B/S模式进行规划、设计,最后,实现并构建了资源加工与生物工程学术信息服务系统。具体而言,本论文主要完成了以下工作:首先,论述了资源加工与生物工程学术信息服务系统的设计思想,认为一个开放互连的平台是连接学术、教学、科研、成果转化、生产应用的桥梁,是促进学术及学科发展、科技成果转化、产学研一体化的重要措施。该平台能否为学术服务,如何实施服务,以及为学术服务的深度及广度等内容,都与平台的设计与构建过程相关。其次,分析并设计了系统的架构模型。本系统将整个系统分为前台和后台两大部分,前台负责用户交互,后台负责数据处理。用户需求来源于资源加工与生物工程学术信息服务系统。整个系统构建在三层B/S模式之上,是一个基于WEB的应用系统。本系统描述了B/S模式的四大典型特性,即:基于互联网Internet而不是局域网的应用;系统的开放性;系统配置的简单性;终端零维护。论述了三层结构的特性:将表示逻辑与处理逻辑分开;将处理逻辑与数据管理分开。在系统的实现过程中,采用了PHP+Apache+MySQL黄金组合策略,即选用了PHP作为服务器端的脚本语言;选用了Apache服务器用来接收和处理系统的WEB请求;选用了MySQL数据库管理系统来实现系统的数据管理。最后,本论文并对系统的构建和实施过程中的关键过程和问题作了详细论述。结合资源加工与生物工程学科的特点,开发出了一个完整的学术信息服务系统。该系统可以进行学术信息的录入、增加、编辑、修改、查询等基本处理以及文件的上传、下载、视频、PDF文件浏览等高级功能,形成了一个完整的、有学科特色的学术信息服务系统。通过对本系统的深入及有效的研究,我们可以得出如下结论:(1)规划、开发资源加工与生物工程学术信息服务系统不仅是必要的,而且是可行的。(2)开发可采用传统的结构化方法与现代面向对象思想相结合的思路来实现。(3)系统可分为前台和后台两部分,两者在逻辑上相互独立。(4)系统采用三层基于B/S模式,使得表示、逻辑、数据三者独立,并且设计成中英文两个版本。(5)可以将本系统的架构移植到其他专业的学术信息服务系统,从而形成一个通用的学术信息服务系统。本论文的创新之处,一是设计并实现了资源加工与生物工程学术信息服务系统的架构;二是提出了学术信息服务系统的总体拥有成本TCO(Total Cost of Owning)的概念,并用它作为开发模式的依据;三是在现有的架构模型的基础上,抽象出了学术信息服务系统(中英文版)的通用架构;四是提出了学术信息服务概念的内涵,特别是将项目融资的内容加入到其中,突出了学术领域中产、学、研的一体化的思想。更多还原

【Abstract】 To an academic information system,sharing is the base of com- mu nication,while the communication is the guarantee for service,w- hich must be built on the platform.The intention of this paper is to m- eet the user’s current and intending requirements,and to scheme,de- sign and develop an academic information service system for source processing and biologic engineering,and serve for academy,science research,product practice,enterprise financing,etc.The structured development method is adopted in the system,and the system is divided into two parts:front platform and backward one, the "divide and conquer" thought for a large system is realized.Then,in the process of architecture design and development,modern thou- ght of object_oriented and web-based technology and three-layers B/S pattern are adopted;in the end,the academic information service system for source processing and biologic engineering are implem- ented.In detail,these works are described and finished in the paper:At first,the design thought of academic information system for source processing and biologic engineering field is demonstrated.According to it,an open and interlinked service platform is a bridge am- ong academic service,teaching,science research,achievement tran- sforming and production application.It plays an important role in im- proving academic research and subject development,promoting the science and technology achievement transforming,and integrating of producing, teaching and science researching.Whether the platform can serve for the learning and science research or not,how to serve for them,and how much is the depth and width of the service,these dep- end in large part on the designing and building process of the platf- orm.Secondly,the architecture model of the system is analyzed and developed in this paper.The whole system is divided into two parts:the front platform and the background one.The user interacting is done by the front platform while the data processing is done by the background one.The whole system,as a web-based one,is built on the B/S pattern. The four typical characteristics of this kind of system are demonstrated in the paper,that is,the application of Internet- based but not local network-based;the open property;the simpleness of system configuration;no-maintenance for terminal.And the perso- nalities of three -layers are described:separating representation logic layer from processing one,and separating processing one from data management one.Within the system realizing process,the PHP+Apac- he+MySQL,as a gold combination strategy is adopted.According to the strategy,the PHP is used as web script language,the Apache as acceptor and processor for the request of user,and MySQL as data- base management system to realize data management.In the end,those main key problems and solutions for the system designing process are demonstrated in the paper in detail.Combined with the characteristics of subject of"source processing and biologic engineering",an integrated academic information service system has been realized.The system can actualize academic information’s basic processing,including inputting,appending,editing,modifying,searching and advanced function,that is,file transferring and down-loa- ding, video on demand and PDF file browsing,thus,an academic info- rmation service system which is integrated and full of subject charac-teristics is formed.After detailed and effective studies for the system in the paper,we can draw conclusions as follows:(1)Scheming,developing the academic information service system is not only necessary but also possible.(2)For the system development,the traditional structured method and modern object-oriented can all be adopted.(3)The system can be,divided into two parts:the front platform and the background one,and the two parts are individual each other. (4)Three-layer B/S pattern is adopted for the system,which make the representation logic layer,processing one and data management one be individual each other.And two kinds of versions are designed and realized:Chinese and English.(5)We can transfer the architecture of the system to another subje- ct’s academic information service system,thus,a general academic information service system can be informed and realized.One of the innovations of this paper is,having been designed and realized the architecture of resource processing and biologic engineering academic information service system;another one is,having put forward the conception of TCO(Total Cost of Owning),and put it as one of the bases of the development pattern choice;The third one is,on the base of existing architecture model,a general one of all academic information service system is abstracted;the fourth one is,the mean- ings of academic information system are put forward,especially the meaning of project financing is added into the system,thus can inform an integrated system of producing,studying and science researching,that is the very important opinion we emphasize on in this paper at all times.更多还原
