The invention discloses a system and a method applied to a P2P network lending enterprise data access model. The system is divided into three modules, namely a data access module, a data preprocessing module and a data loading and storage module, wherein the data access module completes identity authentication of a network lending platform and normalization of a data access interface; the data preprocessing module completes data integrity and validity verification, establishes all kinds of data integrity and validity verification rules and performs de-weighting and correction operation on data; and the data loading and storage module completes a large-scale data secure storage technology and provides secure and convenient data support service for data analysis modeling. The system and the method have the advantages that a normalized and unified standard can be formed for a large amount of heterogeneous data in the network lending platform, normalized, secure and stable data access can be performed, and a data foundation is laid for P2P network lending platform supervision.
