The invention discloses a configurable
system for externally providing multi-source interface data, which comprises a flow arrangement engine, a
data processing engine and a
data processing engine, and is characterized in that the flow arrangement engine comprises a visual node arrangement interface, a dynamic input parameter module and a flow variable
pool; through version isolation, new version configuration is automatically generated when a user modifies a process, an old version continuously processes a stock request until the stock request is completed, and a new request is automatically routed to the new version, so that service switching is non-aware, and the risk of service interruption caused by
server stopping and restarting in a traditional scheme is eliminated; free combination of heterogeneous
data source nodes through a graphical interface and dynamic adjustment of an execution sequence are supported, the solidification problem of a traditional
hard coding process is solved, a
process variable pool temporarily stores an intermediate result of each node for a subsequent node to reference through a preset format, the limitation that a multi-step result cannot be reused in a traditional scheme is solved, and flexible series connection of heterogeneous data sources is achieved; each configuration version has an independent
process variable pool, an
intermediate variable generated by an old version only serves a self task, a variable pool of a new version is completely isolated, data cross
contamination during parallel of multiple versions is avoided, and result consistency is ensured.
