1.1 Project Development Background
With the rapid socio-economic development, people's living standard has been significantly improved, but the attendant social problems is also increasing. One of the most significant is the employment issue. To this end, the Chinese government has also put forward the policy of "promoting employment through entrepreneurship", offering innovation and entrepreneurship courses in universities to improve the overall quality of college students, enhance their understanding of innovation and entrepreneurship, and their ability to innovate and entrepreneurship. In terms of the forms of undergraduate entrepreneurship in my country, the main problems faced by undergraduate innovative entrepreneurs are: passive entrepreneurial motivation, unsteady entrepreneurial will, lack of social resources, insufficient venture capital, lack of market and social experience, low degree of socialization, and unity Poor cooperation ability, imperfect social security, etc. Therefore, encouraging college students to innovate and start businesses is an important means to solve the employment difficulties of our country's college students, and it is also a key strategy to promote the country's economic development. It can make our country become a big country with comprehensive strength faster and earlier.
1.2 Significance of project development
At this stage, various domestic colleges and universities have successively established their own campus networks to improve the narrow and inefficient information channels of their respective graduate schools in teaching and learning, scientific research, and administrative management. Connect with top universities outside the country. But in fact, there is still no progress in the development of the network-based employment management information system, and the real interconnection effect of the network is not fully utilized. According to the survey, there is currently no mature employment management information system software products at home and abroad. Although some colleges and universities are already using employment websites, on the whole, their functions are relatively single and have limitations. It is roughly manifested in the following points: posting recruitment information on search engines; only recruitment information of employers but no self-recommendation information of unemployed persons; no specific and classified employment consulting system. Most of the functions are only the publication of employment information, the publication of static statistical results of employment information and simple employment information query, its practicability and interactivity can no longer meet the needs of college students' employment form, which leads to the blind employment of college students. Therefore, it is urgent and necessary to open a complete set of college students' employment management information system.
1.3 The main content of the project The main content of

2 Introduction to related technologies and system environment development conditions
2.1 Introduction to related technologies
Java, as an object-oriented development language, not only absorbs the various advantages of many languages, but also its entire ecology is the best openness among all languages. In learning, you can find a lot of similar functional codes for future reference and learning. For example, the current asp.net development language is largely imitating the thinking of java. If you learn java programming, you can master another language and learn. It's very fast, because of its simplicity and structural orientation, which reduces the complexity of code management, makes the programming process clearer, and logically decouples more layered.
As a project version management software, Maven can better manage the use of jar packages. There was no Maven management tool before, and many versions of jar packages need to be downloaded online. Sometimes the incompatibility between versions affects the use of the system. Play, sometimes different bugs appear, after using the Mavern project, this difficult problem can be eliminated very well.
MySQL is an open source relational database. Because it is open source, there is no copyright dispute. Now many companies are using MySQL as database storage. Not only its storage rate is relatively fast, but it can also be used for secondary development. Customize a database that is more suitable for the company.
2.2 System environment development conditions

3 system Demand analysis and design
As in the software development process, the project needs to be analyzed. First, we must understand what the business does, what kind of function it implements, and subdivide the use background of each functional module in the functional module. Only in this way, in software development, It will not recur because of the flaws in the architecture design, leading to the occurrence of the underlying data structure of the secondary design. In addition, some non-functional features, such as database performance, security considerations, and network speed reflection time, are all used as constraints for demand analysis Conditions are also targets that need to be analyzed at runtime after project development is completed.
System data integrity The
system data is connected to the database, and the data is complete to enable the system to complete various operations. In order to ensure the orderly progress of various operations, the data information record must be complete and not empty. At the same time, the data of the same user must be consistent , To ensure the accuracy of the data.

3.1 Feasibility analysis The feasibility analysis of
the system is essential in the process of system development. The feasibility study is to evaluate whether the problem can be solved and to be solved with the least time and the least cost. In order to achieve the above goals, the advantages and disadvantages of the methods to solve these problems must be considered, and the economic benefits brought by the development of these systems must also be considered. Here we can use technical feasibility, operational feasibility, and economic feasibility to conduct a feasibility study of our system.
3.1.1 Social feasibility: Demand analysis is the foundation of the entire entrepreneurial project management system design process. Its quality directly affects the quality of the entire entrepreneurial project management system. The demand analysis stage is mainly based on in-depth research and analysis. Clarify the requirements of the system, including data requirements and business processing requirements around these data. If the requirements analysis is not done well, or the user's requirements are not clear, the entire database design, development and coding work will need to be reworked. This system focuses on research from the organizational structure and functions of the entrepreneurial project management system, work flow, data analysis, functional requirements, system use case models, performance requirements, etc.
3.1.2 Technicality: The system designed in this project mainly adopts layui front-end development, the back-end uses java language and springboot integrated development framework, adopts mysql database, according to one's own major, combined with online case list and library materials, development and realization There is no big problem.
3.1.3 Economical: The development of a mature software requires a long process. The design of software needs analysis, planning, development personnel, testing links, and debugging process all require capital and manpower input. And the development of this set of software can be learned through online open source source code and related materials. The hardware and computer use are all used by oneself, so the development cost can be ignored.
Since the design of the system has relatively low requirements for computer software and hardware, existing equipment can be fully utilized without the need to purchase additional software and hardware equipment, and the expenditure on software and hardware is negligible. In addition, the system development is developed by the internal IT technicians of the unit, and the expenditure on labor costs is very limited. After a series of investigations before the system design, it is shown that the cost of the system design is very low. Once the system is developed and put into use, it will greatly reduce the workload of managers, thereby greatly improving the efficiency and quality of entrepreneurial project management, so it is completely feasible from an economic point of view.
3.1.4 Operability: The functions designed by this system mainly include user management module, employment policy module, employment service management module, tripartite agreement module, and college management module. The relevant knowledge of these functional modules is usually designed Common functions are all achievable in operation.
3.2 Demand analysis
By understanding the needs of users, we can know that simple-to-operate systems are more likely to be favored by users, and at the same time can manage information accurately and completely. After the travel recommendation platform analyzes the needs accordingly, it comes to the conclusion that the system is mainly divided into five roles: administrator, enterprise, teacher, student, and employment office.
The administrator module is mainly used for data update management. The functions are divided into system user management and college information management; the employment module functions are divided into employment management, employment service management, statistical information, and user information; the enterprise module functions are divided into user information and employment policies; The function of the teacher module is divided into tripartite agreement, statistical information, and user management; the function of the student management module is divided into user management, tripartite agreement, employment policy, and employment service management. The use case diagram is shown in Figure 2-1.
3.2.1 General overview of
the system This system plans to use the development tool IDEA for program development, and database sql for database design. The employment project management information that the system needs to manage is obtained by investigating the university student employment project management system. Carry out the division of functional modules, and design each functional module according to the design principle of high cohesion and low coupling, and allocate the input and output information of each module. Finally, the program and database are designed.
The project management system is mainly based on the B/S design model. The functions of the system design include: user management module, employment policy module, employment service management module, tripartite agreement module, and college management module. The system structure is shown in Figure 3-1:
3.2.2 Functional requirements
This system is designed and completed by using modern computer network technology to integrate traditional information propaganda methods. At the same time, the service is improved, and a student employment management system platform is initially designed to facilitate the operation of related affairs. In order to make the system play a greater role in various management and realize computerized and efficient management, the development target function requirements are now introduced as follows:

3.2.4 The flow chart design
employment workflow management system for the students:
. The following is the overall flow chart design as
shown in Figure 3-2: Figure 3-2 The overall flow chart design
Login management flow chart: The login management function is the management entrance of the system, and of course it is also the highest level of system protection. If there is no good security prevention and control mechanism, the system will be vulnerable to attacks; for this, the following are the main considerations when designing Aspects. The following are as follows: 1. Verify that the user name and password are recorded in the database table; 2. Verify that the user name and password input is legal, especially SQL injection to prevent intrusion into the system and tampering with permissions; 3. When the user logs in to the system, it will be provided for each user A seesionID has an expiration time of 30 minutes. If the user does not use the system for a long time, the system will automatically jump to the login page after 30 minutes. The following is part of the flow chart design, as follows:
3.2.5 System ER diagram design and
development of applications, the operation of the database is indispensable, the database design is determined according to the needs of the program and its realization function, the rationality of the database Will greatly affect the development process of the entire system.
This system uses the mysql database. The database design is a key issue in the realization of the Internet system. A good database structure can ensure the smooth progress of the database system. On the contrary, the blind establishment of an unreasonable database often results in the system running poorly and even halfway through. Conceptual structure design occupies a core position in the entire database design. It can synthesize, summarize and abstract system requirements to form a conceptual model that does not depend on specific database management systems, that is, ER diagrams. ER diagram can be used to visually present and analyze the relationship between data.
The user management module includes employment offices, enterprises, administrators, students, teachers and other roles. It can manage the user management module, employment policy module, employment service management module, tripartite agreement module, and college management module respectively.
