- determining relationship data among all domain entities in the domain model diagram based on a first representation vector of the domain model diagram;
- determining a data source entity relationship, a data stream relationship, and impact factors of the at least two data sources based on the relationship data and the at least two data sources;
- and
- generating a dashboard for visualizing data streams of the service system based on the data source entity relationship, the data stream relationship, and the impact factors.
