Graphic of databse workflow. The graphic shows that "data sources" (IoT: soil & weather, rover: image & point cloud, drone: imagery data, manual: height, boll count. nodes count, etc.) are ingested into a box called "data loader (JMeter Scripts)." The data then is inserted into both "Database (MongoDB) and "Database (Neo4j)." The data goes through "workload test" and goes into a single "performance testing (JMeter: CRUD, Queries)." The data then goes through "collect results" into "Metric collection (CPU, RAM, response time)." The save logs go into "Result storage (CSV)" and are analyzed into "visualization & analysis."
