Introduction
This program is a major database assignment in my sophomore period. I wrote a program after learning the database. It is a student dormitory management system, which can realize the management of student dormitories.
This program is written in Java and developed using eclipse. The database uses MySQL database with Navicat for data management. The program uses JDBC technology for database connection, and Java Swing is used to develop a graphical interface. The entire system has a beautiful interface and rich functions. Click the "Change Appearance" button on the homepage of this system to switch the appearance of different styles. The system is divided into three modes, student mode, dormitory management mode and system management mode, which are respectively oriented to students, dormitory management and system administrators. The different modes are as follows: For different functions, please refer to the introduction below for details.
This system has complete and rich functions (you can export all kinds of information in the system as excel files), the program has strong error detection ability, and the interface is simple and beautiful (every component has been carefully adjusted), but it was lazy at the time, so some codes were not available. After optimization, it may be a bit complicated, and for the sake of beautiful interface, most of the code is adjusting the interface components, please don't mind, readers can take the essence and discard the dross.
The program source code and program design manual can be downloaded by clicking the link below for your reference.

Table of contents
data design
There are 8 tables in the database of this system. The database table design and ER diagram are shown below. For detailed data design, please download the data design table or program design manual at the beginning of the article to view it.
Procedure flow chart
The general flow of the program is as follows:
function display
This program has a lot of functions and details, and only some of the functions are shown here. If you want to know the complete functions and details, please download the program at the beginning of the article and experience it.
Welcome interface - change the appearance
Open this program, you will first come to the welcome interface, where you can choose student login and administrator login, click "Change Appearance" in the upper right corner to change the overall appearance of the system, there are 5 different styles of appearance.
Log in
Click "Student Login" on the welcome interface, and then enter the student account and password. If the login is successful, the system will enter the student mode; click "Administrator Login", and then enter the dormitory management account password. Enter "admin", the system will enter the system management mode.
student mode
The student mode is aimed at students. After entering their account number (student number) and password, students can enter the menu interface of the student mode, where they can select corresponding functions. The functions of the student mode are less, and the functions are as follows.
personal information
"Personal Information" function, you can view your personal details.
Dormitory repair
The function of "report for dormitory repair" allows you to report for dormitory repair on this interface, and the submitted information will be saved in the database and displayed on the corresponding interface of the dormitory management mode and system management mode.
Suggestions and Feedback
The "suggestion and feedback" function allows you to make suggestions and feedback on this interface, and the submitted information will be saved in the database and displayed on the corresponding interfaces of the hosting mode and system management mode.
change Password
"Change password" function, you can modify your own password on this interface, you need to enter the old password and the new password twice, and there will be a corresponding prompt if you enter an error.
system management mode
The system management mode is aimed at system administrators. After the administrator enters the specified account number and password (both admin), he can enter the menu interface of the system management mode, where he can choose the corresponding functions. The system management mode has the most functions. It can manage students, dormitory management, and dormitories in an all-round way. The specific functions are as follows.
management function
In the system management mode, the dormitory, dormitory, dormitory management, students, and accommodation information can be fully managed, including adding, deleting, modifying, checking, etc. The following uses "student management" as an example to demonstrate the management functions.
Click "Student Management" to enter the student management interface, where you can see the simple information of all students.
Click the "View" button of a student row to view the detailed information of the student, where the student information can be modified and deleted.
For example, click the "Modify Student Information" button to modify the student information. After the modification is completed, click "Save", and the information will be updated synchronously in the database.
Click the "Add" button on the top of the "Student Management" interface to add students to the system. After entering complete student information and confirming the addition, the information will be saved to the database and the student is successfully added.
Click the "Export" button on the top of the "Student Management" interface to export student information into an excel file.
Click the "Query" button on the top of the "Student Management" interface, you will come to the student information query interface, enter the specified conditions and click "Query", the system will query the eligible students, as follows to query all 2019 students.
The above shows the "Student Management" function, and other management functions are similar.
bedroom assignment
The "dorm allocation" function can automatically allocate dormitories to students instead of manual allocation to save manpower. If you want to allocate dormitories accurately and according to your wishes, you need to manually allocate dormitories on the "accommodation management" interface.
check-in
The "Entry and Exit Registration" function can register the records of students entering and leaving the dormitory building, and can add, delete, export, and query the entry and exit records. Click the "Registration" button above to add entry and exit records, and enter the corresponding information. Name, click "Get Current Time" on the right side of the interface, the current time can be automatically obtained and entered automatically.
Dormitory repair
"Dormitory repair" function, in this interface, you can view the dormitory repair information submitted by all students. Click the "View" button to view detailed repair information. In the repair report detailed interface, you can process and delete the report, and the dormitory repair information can also be exported. and query.
Suggestions and Feedback
"Suggestion and Feedback" function, in this interface, you can view the suggestions and feedback submitted by all students. Click the "View" button to enter the detailed interface to view the detailed content, and you can also delete it here. Suggestions and feedback can also be exported.
Delete library and run away
"Delete database and run away" function, this function needs to enter the password "ESCAPE", and then click the "Confirm to delete database and run away" button to delete the database of this system and run away. After this function is successfully executed, it will automatically exit the program . The system will no longer be usable.
host mode
The host management mode is aimed at the host management group. After the host management enters its own account number (ie number) and password, it can enter the menu interface of the host management mode, where you can select the corresponding functions. The functions of the host management mode and the system management mode Similar, but the difference is that in the dormitory management mode, the dormitory management can only operate the dormitory buildings it manages. Since the functions of the two are similar, the functions of the dormitory management mode will not be shown here. Readers can download the program to experience it by themselves.
code display
There are a lot of codes in this program and detailed notes. Only some important codes are shown here. For the complete codes, please download the program at the beginning of the article to learn more.
For the sake of the aesthetics of the system interface , many codes of this program are adjusting the interface components, please don't mind.
