2.1∣Demand analysis and data collection
Through the investigation of multiple residentia, it was found that almost all of the communities under investigation did not use the property management system, and still used manual ”work” methods to manage the communities. At the same time, a large number of texts, tables and graphics were collected during the survey. Analyzing the received data, it is found that the data is diversified, the format is random, and the filling is random, which involves all aspects of property management. Organize and analyze the collected data, extract data structure and functional requirements, and determine the system development technical framework.
