Abstract:In order to solve the problems of the enterprise informatization features not obvious, variable factors are uncertain, and whether the enterprise can not ensure profitability, the enterprise informatization complementary system is designed under the large data environment. The system improves the hardware part of the complementary system according to the phased characteristics of the complementarity mechanism of the enterprise informatization. The complementary variables are set up by means of enterprise informationization capital survey, the investigation speed of enterprise informationization capital is raised, the complementary function is set and analyzed, the difference of complementary mechanism between small and medium-sized enterprises and large enterprises is analyzed, the optimization of system software is completed, and the design of enterprise informationization complementary system under big data environment is realized. The traditional and improved complementary systems are compared to verify the operation benefits of implementing the enterprise information-based complementary systems in the big data environment.The experimental results show that the system can ensure the long-term profitability of enterprise operation and obtain good profits. The design of this system also provides a good external environment for domestic and foreign enterprises to complement each other.
