How should I design a design sol... from 陈豪's blog

User interface is the window of human-computer dialogue, which must be considered in the design of LEUNG Chi hong. User interface design should adhere to the principle of friendly, simple, practical and easy to operate as far as possible, and avoid tedious and fancy interface.

The main user interface design methods are menu mode, session mode and prompt mode.

The module design of the system is to prepare the detailed process of each module in accordance with the requirements of the overall system design for each module processing function, considering the characteristics of the system development environment and development tools. When designing the modules, attention should be paid to the principle of modularity, i.e., the modules need to have their own independent operation capability and be connected to the outside world through only one interface.

The design plan of the system consists of a system outline design specification and a module design specification.

The purpose of the outline design specification, also known as the system design specification, is to explain the design scheme of the system. It includes the design of the application system, the system operation platform and the design of the system operation network structure and equipment.

The main contents of system implementation include implementation of physical system, establishment of database, program design, system testing, personnel training, system conversion, system import and system maintenance, etc.

Program design is a very important step in system implementation. The program design work is based on the description of the module processing process in the system design specification, choosing a suitable computer language and preparing a correct, clear, easy to maintain, easy to understand and efficient program.

System testing includes broad testing and narrow testing. The broad system testing is considered from the perspective of ensuring the safety and effectiveness of system operation, and all errors that may lead to system operation failure should be tested before the system is put into formal operation. Therefore, the system testing should include testing of equipment, network testing, testing of various operating platforms and testing of application software.

The process of introducing ERP systems in enterprises is divided into four main phases: project initiation, introduction preparation, implementation and integration and continuous change.

In order to improve the organization's information technology efforts, the development and application of management information systems need to be evaluated to accumulate experience and lessons learned for future development.

With the change of management environment and the development of information technology, the management information system has undergone great changes, from a system supporting management operations to a system supporting information resource management and decision management, and from supporting internal management to supporting external management. In this development process, new systems and concepts such as information resource management, e-commerce, geographic information systems, decision support systems, data warehousing and data mining have emerged.
