Research and Practice on Business Architecture Construction of Large Integrated System

With the gradual deepening and expansion of the scale of enterprise information construction, it is increasingly required that the system can break business barriers and data barriers, so that it can realize a new software design idea of data sharing, technology sharing and collaboration. Based on the experience of large-scale integration projects, this paper first analyzes the maturity of enterprise business, discusses how to do a good planning and design in the conceptual stage of project start-up, and promotes the whole process management of the project. Next, it enables demanders and developers to communicate effectively under a unified business architecture, and with the help of big data technology, allows designers to sort out the focus of the public and ideal deliverables based on data analysis of various indicators accumulated by previous systems. Finally, the project team can achieve the output of deliverables quickly and accurately. This method has great development potential for software R & D, and it can be widely used in major enterprises. It also brings effective solutions for later enterprises in the face of complex integrated projects.
