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.
