Join William Lyon for an in-depth discussion in this video Insights on calculations in Neo4j, part of Database Clinic: Neo4J.
- [Instructor] This problem asked us…to compute population forecasts…by combining two datasets and querying across them.…In order to combine the datasets,…we refactored our graph data model.…Once we did that, importing an additional dataset…on top of our already existing database…was just a matter of writing a simple…LOAD CSV Cypher statement.…Having worked with Neo4j for a while now,…one aspect of data modeling that I've noticed…is the flexibility of the graph.…It's very easy to not only refactor…and evolve the data model,…but also to extend it by adding new datasets.…
This is actually a very common approach…to graph data modeling.…It's a much more agile process than other systems…where we might need to deal with…things like schema migrations.…We also took advantage of Neo4j's…extensibility in this problem.…We installed the APOC procedure library…and used two procedures,…one for splitting up our refactor…across multiple transactions,…and another for parsing date strings.…Having this user-defined procedure framework…
