Abstract:In response to present condition of low collaboration in land use business and the lack of a fully established business lifecycle management mechanism, taking the "one code association" construction project as the starting point, business process has been optimized and the construction and application of "one code management of land" have been carried out . Through associating spatial graphics of different business stages, by using "codes" as the unique identifier, using "resource codes" to connect the entire business processes of construction projects together, such as "planning, review, use, supply, construction, inspection, and registration", a complete data chain has been formed, the sharing of process data and achievement data have been achieved, and full process information has been traceed. This can effectively ensure business applications issuing certificates upon delivery and acceptance, and furtherly optimize the business environment.
