Chapter One Introduction
1.1 Background of the project research
The student dormitory management system is an essential part of a school. At present, many schools are still in the initial stage of manually recording data by dormitory managers. Manual recording is barely acceptable for small-scale schools, but for colleges and universities with a large amount of student information and a large amount of data that needs to be recorded and archived, Manual recording is quite cumbersome. And when looking for a certain record, due to the huge amount of data, you can only search one by one manually, which is not only troublesome but also wastes a lot of time, and the efficiency is relatively low. Today's society is a world of rapid progress, the original recording method has been eliminated by the society, and computerized management is the product of adapting to the times. The information world will never be a peaceful world. When a technology cannot meet the demand, a new technology will be born to replace the old technology. Today in the 21st century, The information society occupies a mainstream position, the use of computers in all walks of life has been popularized, and automation and information management are more and more widely used in various fields. We have designed a set of student dormitory management system for this. The student dormitory management system adopts computerized management. The system is as humanized as possible. Users will feel that the operation is very convenient. All the administrators need to do is to input the data into the system database. Since the database storage capacity is quite large and relatively stable, it is suitable for long-term storage and is not easy to lose. This undoubtedly provides a convenient and fast operation method for schools with a relatively large amount of information storage. This system has the advantages of fast running speed, high security and good stability, and has perfect report generation and modification functions, and can quickly query the accommodation information required by the school. Student dormitory is an important space environment for college students to study, live and communicate on campus. College students spend about 2/3 of their time in the dormitory environment. With the expansion of the scale of colleges and universities, the academic level, ideological state and cultural level of the students in the school are diversified and complicated, which has brought many new problems to the student management work to a large extent. With the increase in the number of students, the amount of information in the management of student dormitories in colleges and universities is increasing. At present, the management of student dormitories in our school still adopts the traditional working method-the book-based working mode. This mode is slow to obtain information, difficult to consult, and poor in accuracy. , it is difficult to adapt to the needs of high-level dormitory management, and at the same time it brings a lot of waste of manpower, which brings a lot of inconvenience to the work of dormitory management. Based on this, we thought of the need to develop a "student dormitory management system" to improve the management efficiency of the dormitory, improve the management method, and make it in line with the trend of modern informationization. Since the storage capacity of the database is quite large and relatively stable, it is suitable for long-term storage and is not easy to lose. This undoubtedly provides a convenient and fast operation method for schools with a relatively large amount of information storage.
1.2 Project selection and purpose significance
The user who chooses the student dormitory management system as the topic will feel that the operation is very convenient. All the administrators need to do is to input the data into the system database. Since the database storage capacity is quite large and relatively stable, it is suitable for long-term storage and is not easy to lose. This undoubtedly provides a convenient and fast operation method for schools with a relatively large amount of information storage. This system has the advantages of fast running speed, high security and good stability, and has perfect report generation and modification functions, which can quickly query the accommodation information required by the school, and facilitate the management of student dormitories by colleges and universities.
1.3 Objectives and Requirements of Project Research
Overall goal: to successfully develop a student dormitory management system. Realize functions such as querying, adding, and deleting student dormitory information, which is convenient for management and saves manpower.
Tasks and requirements: be able to operate the dormitory management system to achieve the purpose of management. Requirements: Beautiful interface, complete functions such as adding, deleting, and querying.
Chapter Two Feasibility Analysis and Demand Analysis
2.1 Feasibility analysis
2.1.1 Operation Feasibility
The operating system used in this system is windows10, which is relatively simple to operate for people who have entered the Internet age, and it is feasible in terms of operation.
2.1.2 Technical Feasibility
This system is developed by combining technologies such as spring + springmvc, and it is technically feasible. For the development of the interface, the currently popular framework Bootstrap is used, which is very friendly in terms of interaction and easy to operate and develop. In terms of database, mysql is used, which is guaranteed in terms of security, and mysql is more portable.
2.1.3 Design Feasibility
The design of this system adopts the MVC model, which can well divide the page display, business logic processing, and data access. The coupling between each level is low, which greatly improves the flexibility of the project and the overall division of the system. It is relatively clear, so it is also feasible in terms of design.
2.2 Demand Analysis
The student dormitory management system is an essential part of a school. At present, many schools are still in the initial stage of manually recording data by dormitory managers. Manual recording is barely acceptable for small-scale schools, but for colleges and universities with a large amount of student information and a large amount of data that needs to be recorded and archived, Manual recording is quite cumbersome. And when looking for a certain record, due to the huge amount of data, you can only search one by one manually, which is not only troublesome but also wastes a lot of time, and the efficiency is relatively low. Today's society is a world of rapid progress, the original recording method has been eliminated by the society, and computerized management is the product of adapting to the times. The information world will never be a peaceful world. When a technology cannot meet the demand, a new technology will be born to replace the old technology. Today in the 21st century, the information society occupies a mainstream position, the use of computers in all walks of life has been popularized, and automation and information management are more and more widely used in various fields. We have designed a set of student dormitory management system for this.
2.2.1 Processing object analysis
The objects to be processed by the system include basic information of students, basic information of dormitories, basic information of dormitory buildings, basic information of building administrators, and basic information of visitors. The information of each object is as follows:
1. Student basic information (Student): including student number, student name, student gender, student check-in and move-out, student age and student phone number, etc., which can facilitate the query and update of student information;
2. Basic information of dormitory students (Dormitory): including student number, student name, building number, dormitory room, dormitory contact number;
3. Dormitory basic information (Building): including dormitory building number, dormitory building gender classification information, administrator name, etc., which can facilitate the management of the dormitory building and improve query efficiency;
4. Basic information of building administrators (Teacher): including staff number, staff name, gender, work dormitory, and telephone, which can facilitate the appointment, information query and modification of dormitory managers by managers;
2.2.2 Analysis of Functional Requirements
The system mainly completes the following functions:
1. Query and modify the basic information of the dormitory building;
2. Query, update and insert basic information of students;
3. Inquiry and update of dormitory information in each dormitory building;
(1) The dormitory information management system realizes the reading of all the information of students and administrators; realizes the reading of specific information of a student or administrator;
(2) Realize the deletion of a person's information;
4. Check-in and move-out records of occupants in the dormitory building;
2.2.3 Security and Integrity Analysis
Security first passes through the view mechanism, different users can only access the views authorized by the system, which can provide a certain degree of security for system data, and then through the user authorization mechanism, the user is required to log in to identify the user level, and assign users according to this level Permissions to achieve a higher level of data security and confidentiality functions.
Integrity requirements are used to describe the basic information of the dormitory building, the basic information of the students, the basic information of the dormitory, the basic information of the building administrator, and some user-defined integrity (in line with actual requirements)
