The invention is applicable to the technical field of finance, and provides a method and a device for
service development. The method and the device aim to solve the problem that financial
service development and maintenance are high in cost, low in efficiency and low in reliability in the prior art. The method comprises the following steps: obtaining service components that a user chooses and set parameter information, and establishing
service component living examples; associating with the
service component living examples according to associated information of the service components that the user inputs, and forming a visual
service flow chart; compiling the visual
service flow chart, generating and issuing a corresponding
service flow chart file. Through the technical scheme, financial
service development can be simple like block stacking by using the service components, and complicated service becomes easily understood through a visual service
flow chart customizing manner, so that the development difficulty can be reduced, the development efficiency is effectively improved, the
software development and maintenance cost is greatly reduced, and the quality of
software product is improved.
