The education system in China's education industry has been undergoing continuous reform. The current educational resources integration and sharing system is inefficient and needs a lot of time to find resources, which greatly affects the efficiency of education. The integration and sharing of educational resources have become unavoidable problems in teaching. In order to solve this problem, this paper takes the rational planning of educational resources as the research object, analyzes the problems faced by the integration and sharing of educational resources, discusses the main direction of the integration and sharing of educational resources, designs the integration and sharing system of educational resources based on big data fusion, compares it with the traditional ant colony algorithm and cloud computing teaching resources integration and sharing system, and analyzes the performance and efficiency of this system. The educational resources integration and sharing system designed in this paper is closer to the ideal value and has stronger integration and sharing ability.
