The invention relates to the technical field of program development, in particular to a low-code business
system and method based on custom configuration, and the
system comprises: a form engine module, which is used for customizing a form field and a
data field of a
data model; a
process engine module, which is used for customizing a
business process; a
rule engine module, which is used for customizing business models and business generation rules; a center module, which is used for generating businesses according to the custom content of each engine module; a state
machine module, which is used for monitoring the node state of the
business process and identifying and
processing the abnormal condition of the
business process according to the node state of the business process; and a digital twin module, which is used for displaying all the generated business process data, analyzing and evaluating the business process data, performing
simulation testing in combination with historical data when the business process is optimized, and evaluating the optimized business process according to a
simulation result. The
system can flexibly carry out self-definition, carries out monitoring and
objective evaluation on the business process, and helps a user to reasonably optimize the business process.
