Join William Lyon for an in-depth discussion in this video Query data, part of Database Clinic: Neo4J.
- [Instructor] Now lets verify that our data…was imported correctly by writing some queries.…The first thing we can do is inspect the schema…by executing call db.schema.…This will inspect the data that we have on the graph…and show us the graph data model…of the data we have created.…And we can see this matches the data model…that we defined in ERAS,…with a node for population prediction,…a node label for county,…and a for county relationship connecting them.…
Lets query the data to inspect a few data points.…First lets see if we can find San Mateo county.…So lets match on the county mode…where the name property is equal to San Mateo.…And I'm going to hit the control enter key…here to execute a multiple line cipher statement.…And we can see here the San Mateo county node.…We can double click on these to expand out,…and we can see we have a number of population prediction…nodes connected to San Mateo county.…
Lets see if we can answer the question, "How many…"population predictions do we have for San Mateo county?"…
