6、gt;　　Research Status</p><p>　　Many different kinds of student dormitory management systems has developed on the Internet at present, although the function is relatively complete, the interface give a person

7、a kind of very complicated feeling, dormitory management personnel in our school do not have great advantages to learn new knowledge relatively at the age, need some time to learn and adapt for new dormitory management m

8、ode as well, although students as another kind of end user with the ability to quickly learn new knowle</p><p>　　Research Content and Goals</p><p>　　Main features of dormitory management system

9、include the following points:</p><p>　　The system is divided into two identities to log in, one is the dormitory personnel, and the other is student, function of each identity is slightly different after log

10、in.</p><p>　　The dormitory management personnel can mainly realize the inquiry about the</p><p>　　students and dormitory information as well as the addition, deletion and modification of their i

11、nformation after login.</p><p>　　Users can check express information</p><p>　　Users can submit and inquire about repair information;</p><p>　　Students can add or delete their own in

12、formation on leaving and returning to school.</p><p>　　User can change user's own password.</p><p>　　This dormitory management system emphasizes the completeness of functions and</p>

13、<p>　　the friendliness of the interface, which has made a lot of efforts in convenience of use, in order to make the content seem simple and easy to understand without losing the functional integrity, I have designe

14、d many different kinds of window layout, finally choose one of the most satisfactory layout to achieve the object of simple interface.</p><p>　　DEMAND ANALYSIS</p><p>　　Feasibility Analysis of S

15、ystem Development</p><p>　　Technical feasibility: with the development of computer technology, the life and work of people have involved in computer field more or less, now it is hard for people to break awa

16、y from a convenient science and technology, on the whole, the popularization of the computer makes people's life efficiency have a leap. Dormitory management system store is management software which stores a lot of

17、information on students and dormitory, including students and dormitory information' inquiry, addition, </p><p>　　Feasibility of organization and management: a lot of conservative state have got rid of i

18、n the concept of modern people, if the developed management software function is strong enough, it can bring to life, so it can get school logistics support, because no one will give up a chance which can do things easie

19、r, and conservative do inefficient things.</p><p>　　It can be seen from the above feasibility that developing such a management system can make the management of the dormitory more convenient and fast, and c

20、an make the whole management mode improve one step. Therefore, it is necessary to develop dormitory management system.</p><p>　　Users' Needs Analysis</p><p>　　The system's end users are

21、dormitory managers and students. According to my daily experience in the dormitory, investigate the dormitory management teachers in my school and the students in the same dormitory; I come to the practical needs of the

22、following user terminal:</p><p>　　Students live in dormitory, daily life of many dormitory management personnel in</p><p>　　dormitory building.</p><p>　　Student's basic informat

23、ion:</p><p>　　After the students entering the school, the school will automatically generate for each student a primary key, which is the only student ID as well, and it is assigned to the specified dormitor

24、y buildings and dormitory. Each dormitory has a unique dormitory house number; student registration time is the time when students enter school. In addition, students generally with the same college live in the same buil

25、ding ,in order to facilitate the management; there are corresponding department names i</p><p>　　Basic information of dormitory:</p><p>　　Each dormitory has a primary key dormitory number; each

26、dormitory has a phone, it is corresponding to the dormitory phone number.</p><p>　　Basic information of dormitory property project:</p><p>　　The school's public property includes light bulbs

27、, beds, tables and chairs, etc. in order to make better distinction for different items, and item numbers are assigned for each item. The main purpose is to be more conducive to repair and manage dormitory public items.&

28、lt;/p><p>　　Basic information of express:</p><p>　　There is express management in each dormitory. When students have a letter on the building, the arrival time of the letter will show corresponding

29、ly, and accept the letter with student's name and the house number of his dormitory. A student can have several express at one time, it is necessary have column that show the number of express. When the express arriv

30、es, there will be an arrival time. After the student has successfully received express mail, it shows successful receipt.</p><p>　　Basic information of public repair:</p><p>　　The public propert

31、y of dormitory often need to be repaired due to damage, at this time, the students should number the item, item name, and the cause of the damage, and report to the dormitory management system, management will see it thi

32、s time, notify the relevant personnel to repair dormitory property. The report will generate an report time, and have a successful repair time after the repair is completed.</p><p>　　Basic information of nig

33、ht return:</p><p>　　Students sometimes are over the closing time of dormitory because of some things, at this time, dormitory management personnel should make corresponding record on the system, for example:

34、 time of night return, personnel's name of night return, student number, the reason for return late and so on, in order to verify later.</p><p>　　Basic information for leaving school:</p><p>

35、;　　Every year when the school in winter vacation, summer vacation, and all kinds of small holidays, in order to facilitate the students' safety management and know where the students are going, they should do their b

36、est to record where the students are, when they leave and when they return to school.</p><p>　　User's requirements for the system:</p><p>　　Dormitory management personnel:</p><p&g

37、t;　　Information requirements:</p><p>　　The dormitory management personnel can check all the above information, including any information in the student's dormitory, the receipt information of the express

38、, the information of the property, etc., so as to manage the whole dormitory.</p><p>　　processing requirements:</p><p>　　Dormitory management personnel not only can inquire the relevant informat

39、ion, and have the right to change a lot of information, such as the change of students' information changes, which is mainly modified by dormitory management personnel, when students' express arrive, the manageme

40、nt personnel record it, after the express is successfully received, and the dormitory management personnel confirm and receive.</p><p>　　When the student reports the damaged property for repair, dormitory ma

41、nagement personnel can inquire the fixed time, that is to say, the dormitory management</p><p>　　personnel cannot only inquire the students' information, but also have authority to add and remove informa

42、tion.</p><p>　　Safety and integrity requirements:</p><p>　　Safety requirements:</p><p>　　The system has two different users' ID to login, and different user id login has differe

43、nt system window, and should ensure that the users' name and password are legal.</p><p>　　The system has the same access to the same data set, and users can inquire and handle the types and contents of a

44、ll information of the access rights.</p><p>　　The system sets different authorities for administrators and students. Users with different authorities have different access rights and change authorities for d

45、ifferent data, which are divided into dormitory personnel' authorities and students' rights.</p><p>　　Integrity requirements:</p><p>　　All kinds of information records must have data; th

46、e completeness of information must be ensured:</p><p>　　Meticulously linked all kinds of data;</p><p>　　The same data record should be consistent, no matter which page is the same.</p>&l

47、t;p>　　Students in this dormitory:</p><p>　　Information requirements:</p><p>　　The students live in this dormitory can inquire dormitory they live in, students' express, their dormitory pr

82、領(lǐng)域，現(xiàn)在人們很難擺脫這種方便的科學(xué)技術(shù)，總的來說，計(jì)算機(jī)的普及使人們的生活效率有了飛躍。宿舍管理系統(tǒng)存儲(chǔ)是管理軟件，它存儲(chǔ)了大量學(xué)生和宿舍信息，包括學(xué)生和宿舍信息的查詢、添加、刪除、更改等操作、學(xué)生遲到的記錄、宿舍物品的維修登記以及查詢并輸入學(xué)生的信件等。這樣的管理體系的發(fā)展使得對(duì)學(xué)生生活方式的了解變得更容易。該系統(tǒng)使用Eclipse和數(shù)據(jù)庫技術(shù)，Eclipse安全且易于使用，如上所述，數(shù)據(jù)庫使用起來更為方便和簡單，因此開發(fā)管理系統(tǒng)在

83、技術(shù)方面完全沒有問題。</p><p>　　經(jīng)濟(jì)可行性：開發(fā)這個(gè)系統(tǒng)只需要將軟件安裝到計(jì)算機(jī)上，并且可以隨時(shí)隨地進(jìn)行，因此開發(fā)這樣的軟件并不是很大的經(jīng)濟(jì)壓力。</p><p>　　組織管理的可行性：很多保守國家已經(jīng)擺脫了現(xiàn)代人的概念，如果開發(fā)的管理軟件功能足夠強(qiáng)大，那它可以被帶入到生活中去，所以它可以得到學(xué)校后勤部門的支持，因?yàn)闆]有人會(huì)放棄一個(gè)可以使事情變得更容易的機(jī)會(huì)，而不會(huì)保守地做一些
