The invention relates to the field of computer application, in particular to a method, a device, equipment and a medium for integrating a heterogeneous business
system and a
workflow system.The method comprises the steps that
business entity modeling is conducted on business receipts of the heterogeneous
system, and a business table structure, a field type and a
business entity referenced by associated fields are described in a setting form; binding a corresponding heterogeneous
service system data query API (Application Program Interface) for the created service entity; performing approval form modeling, binding a mapping relationship between form control display contents and
business entity fields, generating an approval form, and mapping business form data in real time by the approval form; performing flow modeling, defining a
flow chart and binding a flow event, and calling a heterogeneous
service system data query API to write back service form data at the event
execution time; and modifying a submission button response event of the business form, and calling an
open standard API of the
workflow system to initiate an approval process. And flow
centralized management and control are realized, approval entrances are unified, and consistent approval experience is provided.
