基于JavaEE技术的学生管理系统研究与实现摘要随着信息技术的发展,信息化逐渐扩展到了校园管理、行政办公中,现有学生管理系统因其适应性问题已不能满足目前实际的需要。随着高校招生的增加,学生管理系统的复杂度越来越高,迫切需要借助计算机来实现学生信息管理和统计,更好的为师生提供服务。论文在研究基于优先级回溯的排课算法的基础之上,使用UML建模语言进行业务建模与设计,基于JavaEE平台研发出具有一定特色的学生管理系统,并具有较好的可靠性、可移植性和安全性。论文的主要工作如下:(1)分析当前环境下学生管理的业务应用流程,构建学生管理的业务模型,并进一步应用UML进行用例描述,系统建模与设计。(2)在传统优先级回溯算法基础上,提出基于优先级回溯的排课算法;该算法融入了实际院校的优先级选课因素,有效地提升了排课算法在实际中的应用,解决了资源冲突问题。(3)在前期需求与数据分析基础上,对系统功能模型进行进一步的设计,将JavaEE技术应用到系统的研发过程,完成基础课程维护、学生管理、排课管理等核心功能模块,实现一套完整的学生管理系统。论文进一步结合本校学校学生管理业务实践,将学生管理系统在全校推广试运行,取得了较好的成效。该管理系统上线运行大大地改善了学生管理工作效率,为学校节约了大量的人力、物力,增强学生、班级、教师、专业间的信息交流和互动,促进学生管理工作的开展,对高校实现信息化具有重要的参考意义。关键词:排课算法;JavaEE;优先级回溯;UMLIAbstractWiththedevelopmentofinformationtechnology,itgraduallyextendedtothecampusmanagement,administrativeofficesandtheexistingstudentmanagementsystem.Studentmanagementsystemhasbeenunabletomeetthecurrentactualneedsbecauseoftheadaptability.Withtheincreaseenrollmentofcollegeandtheincreasingcomplexityofthesystem,it’surgenttousecomputerstoachievestudentinformationmanagementandstatistics,andtoprovidethebetterservicesforteachersandstudents.BasedonprioritySchedulingalgorithmsbacktracking,thispaperusedUMLmodelinglanguagetoconductbusinessmodelinganddesign,anddevelopedstudentmanagementsystembasedontheJavaEEplatform.Thesystemhascertaincharacteristics,andhasgoodreliability,portabilityandsecurity.Themainworkisasfollows:(1)AnalysisofbusinessapplicationprocessedinthenewenvironmentofstudentmanagementtobuildthebusinessmodelandfurtherapplicationoftheUMLforcasedescriptions,systemmodelinganddesign.(2)Thetraditionalprioritybacktrackingalgorithmisproposedbasedonpriority-basedbacktrackingSchedulingalgorithms.ThisalgorithmincorporatesfactorsthattheactualpriorityelectiveinstitutionstoeffectivelyenhancetheSchedulingalgorithmsusedinpracticetosolvetheresourceconflicts.(3)Aftertheearlyrequirementsanddataanalysis,wegivenafurtherdesignofthefunctionalmodelofthesystem.UsingtheJavaEEtechnologytodevelopthesystem,thisarticlecompletedthecorefunctionmoduleasbasiccoursemaintenance,studentmanagement,andcourseschedulingandmanagement.Atlastweachievedacompletesetofstudentmanagementsystem.Furtherintegratingtheschoolstudentmanagementpractices,thestudentmanagementsystemispromotedtotestrunintheschool,andachievedgoodresults.Thesystemlineoperationgreatlyimprovedstudentmanagementefficiencytosavealotofmanpower,materialresources,whichenhancedinformationexchangeandinteractionbetweenstudents,classesandteachers,professionalandpromotedtocarryoutstudentsmanagementworkontheuniversity,hadimportantreferencevaluetoachieveinformationtechnology.Keywords:curriculumarrangementalgorithm;JavaEE;Prioritybacktracking;UML;II目录学位论文原创性声明..............................................................................................
