Introduction:
Under the influence of rapid social development, banks continue to develop, greatly increasing the requirements on the quantity, diversity and quality of deposits, withdrawals and loans, making the management and operation of small banks more difficult than in the past decade. Based on this reality, it is very important and valuable to design a fast and convenient small bank management system. For the traditional management model in the bank, the bank management system has many incomparable advantages, the first is the rapid update of order information, followed by a large amount of information management, the last is a high degree of security, as well as the use of simple characteristics, which makes the management and operation of small bank management system is very convenient. With the continuous improvement of network and information technology in modern society, people’s living standard has reached a new level. Developing a management system for small banks is exactly what we need. This paper studies the development and implementation of related management system, from demand analysis, overall design to specific implementation, and finally completed the entire bank management system, so as to facilitate users and improve the management level of the bank.
System design:
The main implementation:
Home page, personal center, announcements, information management, user management, staff management, network management, management of account information, account deposit management, account management, account transfer withdrawal management, online consulting, sales information management, loan product management, information management, and payment information management application management, system management, and other functions, it has a simple interface, Convenient application, powerful interaction, completely based on the characteristics of the Internet.
The whole system is composed of multiple functional modules. It is necessary to list all the functional modules one by one, and then carry out the functional design one by one, so that each module has a corresponding functional design, and then carry out the overall design of the system.
System structure drawing
The following technologies are mainly used:
Eclipse
This system uses Eclipse, Eclipse is an integrated development environment, can be used for Java or mobile applications and other aspects of the program development. It has many powerful functions such as compile, debug, test and publish. Support some other languages such as: HTML scripting, SQL, SPRING BOOT, CSS styles, SPRING, Hibernate, Javascript, etc.
MySQL
MMySQL database is a well-known relational database. It uses a large number of two-dimensional tables to store data rather than encapsulating and storing data in the same “warehouse”, which is very conducive to improving speed and flexibility of data application.
The preferred database for sme website developers is also MySQL. SQL is its standard language. The database is favored by developers because of its size, speed and operating costs, especially its open source technology.
The Spring framework of the Boot
The Spring framework is an open source application framework on the Java platform that provides containers with inversion of control features. Although the Spring framework itself has no limitations on programming models, its frequent use in Java applications has made it so popular that it has since been used as a complement to, or even a replacement for, the EJB (EnterpriseJavaBeans) model. Spring framework for development provides a series of solutions, such as the use of the core features of the inversion of control and realize control FanZhuanLai through dependency injection container management object life cycle, using aspect oriented programming to declarative transaction management, integration of a variety of persistent data access technology management, to provide a large number of excellent Web framework for development, and so on. The Spring framework has the Inversion of Control (IOC) feature, which is designed to facilitate project maintenance and testing and provides a way to uniformly configure and manage Java objects through Java’s reflection mechanism. The Spring framework takes advantage of the lifecycle of container-managed objects, which can be configured by scanning AN XML file or specific Java annotations on a class, and obtained by developers through dependency lookup or dependency injection. The Spring framework has a section-oriented programming (AOP) framework, which is based on the proxy pattern and configurable at runtime. The AOP framework modularizes the cross-concerns between modules. The Spring framework’s AOP framework provides only basic AOP features and, while not comparable to the AspectJ framework, can satisfy basic requirements through integration with AspectJ. Spring FRAMEWORK transaction management, remote access and other functions can be implemented by using SpringAOP technology. Spring’s transaction management framework brings an abstraction mechanism to the Java platform that enables local and global transactions, as well as nested transactions, to work with savepoints and in almost any environment on the Java platform.
