Abstract:The integration of project control and big data technology has practical significance in realizing the three basic objectives of the project. From the point of view of system analysis and design, this paper studies the core architecture and big data application framework of project control platform in big data environment. By identifying the project risk factors, analyzing the project data in the data process layer, this paper construct the target control platform for big data in terms of project progress, quality and cost. The project control platform based on big data can effectively pre-alarm the progress delay, quality problems and excess cost, then provide decision-support analysis for project managers so as to realize the basic goals of the project rationally.
