9、新技术构建一个校园网 络平台,加快学校信息化的进程,改善学校的信息环境,提高信息管理水平和工 作效率,加强对教育教学信息的管理;提高教学水平和效率,提升学校的知名度。天津市三十中学作为一所达到现代化达标标准的普通初中学校,该课题在对校园网平台相关理论进行研究的基础上,采用了先进的B/S开发模式,基于PHP技术和MySQ数据库管理技术对该网站进行设计和开发。解决我校教育教学资源 建设与管理的现实问题。该课题的研究意义体现在:推动我校适应当前信息化技术发展,改善教育教 学信息的管理,提高教育教学资源利用率,加强学校、老师、学生和家长的联系, 提升学校的知名度,使校园网成为学校建设中不可缺少的一个重

10、要组成部分。鉴于以上原因,我选择基于PHP技术的校园网站的设计与实现这一课题,作为 我的论文题目。2. 校园网现状我校地处天津市河北区边远城乡结合地区, 是一所普通初中校,其地位和声 誉都逊于一般学校。在此之前,我校没有自己的校园网站,对于各处室的工作均 是采用纸质办公,往往传达一些通知文件通过最原始的办法。这样既浪费人力又 费时。对于教师的档案管理也比较混乱,常出现经常让老师们上交获奖论文课件 等,但还找不到的情况,不利于学校资源的合理有序的管理和利用。 通过校园网 站改善教育教学信息的管理,提高教育教学资源利用率。学校所招收的学生对学 习缺之兴趣、缺之主动性,往往有厌学、学习困难等现象。调

11、动学生学习的积极 性和主动性,加大宣传,提升学校知名度。针对以情况的分析,一是通过校园网站的“网站信息”、“网站公告”模块加 大宣传,使社会公众对我校的了解不断加深,加大宣传,提升学校知名度;二是 借助校园网站这一平台的“共享资源”、“友情链接”模块,使教师摆脱重理论轻 实践的应试教育理念,合理地采用生动、丰富的现代教育手段以适应我校学生的特点,调动学生学习的积极性和主动性,提高学生的学习效果。3. 需求分析校园网是一个实用性很强的系统,其设计规划和解决方案优良、成败的关键 不在于使用多么价高、性优的设备和前沿的技术,而是看其是否能深入了解学校 的需求,并通过技术反应在应用系统设计中,使有限的

12、资金为学校提供贴切而有 效地服务。我所在学校为天津市三十中学,是一所普通初中校,作为学校的校园网站, 不仅对校内起着信息交流、资源共享、方便办公管理和教学活动以及丰富校园文 化的作用,对外也是学校与外界交流的窗口,具有向社会介绍学校情况,展现学 校特色,与教师、家长和学生的交流。本校园网站设置了四种用户权限: 超级管理员、处室管理员、注册用户和匿 名用户,他们在整个系统中具有不同的功能需求和权限。“超级管理员”主要负责用户管理、公告管理、资源管理和系统管理等;“处室管理员”主要完成本部 门的信息的添加、编辑、删除等操作;“注册用户”可以浏览相关信息,发表评 论,留言、下载学习资源等操作;“匿名

13、用户”是未经注册的网站访客,只享有 浏览页面的权限。另外,还需要网站界面简洁、大方、友好、易于操作。4. 网站的设计与实现4.1网站的设计4.1.1功能设计本系统的功能设计采用 B/S结构(Browser/Server,浏览器/服务器结构)和 模块化的设计思想。它是一个适用于 In ternet环境下的模型结构。所有的模块 按某种方法组织起来,成为一个整体,完成整个系统所要求的功能,每个模块完 成一个特定的功能,且尽量保持其独立性。该网站结构优化,可扩展性强,代码 基于三层架构原理编写,这样既降低了软件系统的复杂性,又有利于提高系统的 可读性、可维护性。根据应用需要,该校园网站从逻辑功能上分为

14、 7大功能模块,其功能结构图,如图4.1,具体说明如下:图4.1校园网站功能结构图1 用户注册与登录:用户分为管理员和普通用户。对当前登录者输入的必要信息,系统根据用户注册时提交并保存在数据库中的信息,进行验证。合法用户通过验证,进入到功能页面,非法用户拒绝登录,并进行相应提示。2 网站公告:公告学校的最新信息和新闻。3共享资源:为师生提供丰富的教育教学资源。4 网站信息:“网站信息”其栏目设置如下,所谓栏目设置就是对要发布 的信息进行归类,使信息发布后显示在相应栏目的对应位置。 该网站设置了学校 概况、党建工作、职能处室、德育在线、教学资源等几个栏目。5站内搜索:在站内实现相关主题或内容的查

15、询。6. 友情链接:对相关的教育教学资源站点进行链接, 共享其教育教学资源, 方便浏览者获取更多的有效资源。7. 站内调查:了解用户对某些问题的意见、观点等,及时调整方针政策。4.1.2 数据库设计在系统的数据库设计中,先要对系统分析得到的数据图中的数据存储进行分 析,分析各数据存储之间的关系,然后得出系统的关系模式。该校园网站是一个 主要面向我校三十中学使用的平台, 数据库的设计要遵循建立数据库的原则, 做 到尽量使用最少的数据库表、最优化的去实现我校校园网功能的需求, 提高数据 存储的效率,保证数据的正确性、有效性、相容性,并使检索数据库做到最简单 和咼效。数据库设计是系统最重要的部分,一

16、个数据库设计的好坏直接影响系统的最 后质量。根据对我校校园网站的需求分析,本系统在数据库中建立了以下主要数 据结构表。表4.1为数据表清单,如表:表4.1 数据表清单序号数据表名称数据表说明1dede adm in系统用户管理表2dede fli nk友情链接表3dede member会员表4dede plus插件管理表5dede sysconf系统参数表6ig dede archive文档主表7s dede m yn ews公告管理表8dede arctype栏目表结构系统用户管理表(表:dede_admin):存储系统中所有后台管理员的用户名、密码、性别、电话、邮箱、登录时间等信息。友情链

30、 one another, and were probably all composed at different times. The main subject is the beatification of the dead, who were supposed to recite the chapters in order that they might gain power and enjoy the privileges of the new life. The work abounds in magical references. The whole trend of the Bo

31、ok of the Dead is thaumaturgic, as its purpose is to guard the dead against the dangers they have to face in reaching the other world. As in most mythologies, the dead Egyptian had to encounter malignant spirits and was threatened by many dangers before reaching his haven of rest. He also had to und

32、ergo judgment by Osiris, and to justify himself before being permitted to enter the realms of bliss. This he imagined he could in great part accomplish by the recitation of various magical formula and spells, which would ward off the evil influences opposed to him. To this end every important Egypti

33、an of means had buried with him a papyrus of the Book of the Dead, containing at least all the chapters necessary for encountering the formidable adversaries at the gates of Amenti, the Egyptian Hades. These chapters would assist him in making replies during his ceremony of justification. First amon

34、g these spells were the words of power. The Egyptians believed that to discover the secret name of a god was to gain complete ascendancy over him. Sympathetic magic was in vogue in Egyptian burial practice, which explains the presence, in tombs of people of means, of paintings of tables laden with f

35、ood and drink, with inscriptions attached conveying the idea of boundless liberality. Inscriptions like the following are extremely common To the ka essential double or soul of so-and-so, 5,000 loaves of bread, 500 geese, and 5,000 jugs of beer. Those dedications cost the generous donors little, as

36、they merely had the objects named painted upon the wall of the tomb, imagining that their ka or astral counterpart would be eatable and drinkable by the deceased. This of course is merely an extension of the Neolithic conception that articles buried with a man had their astral counterparts and would

37、 be of use to him in another world. Pictorial representation played a considerable part in the magical ritual of the Book of the Dead. One of the pleasures of the dead was to sail over Heaven in the boat of Ra, and to secure this for the deceased one must paint certain pictures and mutter over them

38、words of power. Regarding this belief, E. A. Wallis Budge states in his book Egyptian Magic (1889): On a piece of clean papyrus a boat is to be drawn with ink made of green abut mixed with anti water, and in it are to be figures of Isis, Thoth, Shu, and Khepera, and the deceased; when this had been

39、done the papyrus must be fastened to the breast of the deceased, care being taken that it does not actually touch his body. Then shall his spirit enter into the boat of Ra each day, and the god Thoth shall take heed to him, and he shall sail about with him into any place that he wisheth. Elsewhere i

40、t is ordered that the boat of Ra be painted in a pure place, and in the bows is to be painted a figure of the deceased; but Ra was supposed to travel in one boat (called Atet) until noon, and another (called Sektet) until sunset, and provision had to be made for the deceased in both boats. How was t

41、his to be done? On one side of the picture of the boat a figure of the morning boat of Ra was to be drawn, and on the other a figure of the afternoon boat; thus the one picture was capable of becoming two boats. And, provided the proper offerings were made for the deceased on the birthday ofOsiris,

42、his soul would live for ever, and he would not die a second time. According to the rubric to the chapter in which these directions are given, the text of it is as old, at least, as the time of Hesept, the fifth king of the 1st. dynasty, who reigned about 4350 B.C. , and the custom of painting the bo

43、at upon papyrus is probably contemporaneous. The words of power were not to be spoken until after death. They were a great mystery, but the eye of no man whatsoever must see it, for it is a thing of abomination for every man to know it. Hide it, therefore, the Book of the Lady of the Hidden Temple i

44、s its name. This would seem to refer to some spell uttered by Isis-Hathor that delivered the god Ra or Horus from trouble, or was of benefit to him, thus was concluded to be equally efficacious in the case of the deceased. Many spells were included in the Book of the Dead for the purpose of preservi

45、ng the mummy against molding and for assisting the owner of the papyrus to become as a god and to be able to transform himself into any shape he desired. Painted offerings were also provided so the deceased would be able to give gifts to the gods. It is apparent that the Book of the Dead was undoubt

46、edly magical in character, consisting as it did of a series of spells or words ofpower, which enabled the speaker to have perfect control over all the powers of Amenti. The only moment in which the dead man is not master of his fate is when his heart is weighed by Thoth before Osiris. If it does not

47、 conform to the standard required for justification, he is cast out; except for this, an absolute knowledge of the Book of the Dead safeguarded the deceased in every way from the danger of damnation. A number of the chapters consist of prayers and hymns to the gods, but the directions as to the magi

48、cal uses of the book are equally numerous; the concept of supplication is mingled with the idea of circumvention by sorcery in the most extraordinary manner.There is a lso evidence of a higher proportion of perinatal complications (complications arising around the time of giving birth) among childre

49、n with autistic symptoms. These complications include maternal bleeding after the first trimester and meconium in the amniotic fluid. (Meconium is a substance that accumulates in the bowel of the developing fetus and is discharged shortly after birth.) Some evidence suggests that the use of medicati

50、ons during pregnancy may be related to the development of autistic symptoms. As newborns, children with autistic behaviors show a higher rate of respiratory illness and anemia than healthy children. ALLERGIES, INFECTIONS, AND IMMUNIZATIONS. Some professionals believe that autistic disorders may be c

51、aused by allergies to particular fungi, viral infections, and various foods. No controlled studies have supported these beliefs, but some parents and professionals report improvement when allergens and/or certain foods are eliminated from the diet. Viral infections of the mother, such as rubella, or

52、 of the young child, such as encephalitis, mumps, and measles, occasionally appear to cause autistic disorders. The issue is not how hazardous boxing is but whether the hazards are acceptable. The term autism refers to a cluster of conditions appearing early in childhood. All involve severe impairme

53、nts in social interaction,;grappling,communication, imaginative abilities, and rigid, repetitive behaviors. To be considered an autistic disorder, some of these impairments must be manifest before the age of three. The reference book used by mental health professionals to diagnose mental disorders i

54、s the Diagnostic and Statistical Manual of Mental Disorders , also known as the DSM. The 2000 edition of this reference book (the Fourth Edition Text Revision known as DSM-IV-TR ) places autism in a category called pervasive developmental disorders . All of these disorders are characterized by ongoi

55、ng problems with mutual social interaction and communication, or the presence of strange, repetitive behaviors,interests, and activities. People diagnosed with these disorders are affected in many ways for their entire lives. Description Each child diagnosed with an autistic disorder differs from ev

56、ery other, and so general descriptions of autistic behavior and characteristics do not apply equally to every child. Still, the common impairments in social interaction, communication and imagination, and rigid, repetitive behaviors make it possible to recognize children with these disorders, as the

57、y differ markedly from healthy children in many ways. Many parents of autistic children sense that something is not quite right even when their children are infants. The infants may have feeding problems, dislike being changed or bathed, or fuss over any change in routine. They may hold their bodies

58、 rigid, making it difficult for parents to cuddle them. Or, they may fail to anticipate being lifted, lying passively while the parent reaches for them, rather than holding their arms up in return. Most parents of autistic children become aware of the strangeness of these and other behaviors only gradually. Imagine too the state of even the winners hands, protected only by having been soaked in br
