Neo4j：Data Model Transformation：From Relation To Graph

Here are some tips that help you with the transformation:

• Each entity table is represented by a label on nodes
• Each row in a entity table is a node
• Columns on those tables become node properties.
• Remove technical primary keys, keep business primary keys
• Add unique constraints for business primary keys, add indexes for frequent lookup attributes
• Replace foreign keys with relationships to the other table, remove them afterwards
• Remove data with default values, no need to store those
• Data in tables that is denormalized and duplicated might have to be pulled out into separate nodes to get a cleaner model.
• Indexed column names, might indicate an array property (like email1, email2, email3)
• Join tables are transformed into relationships, columns on those tables become relationship properties
