Neo4J data integration pipeline
Background We’ve been using Neo4j for around five years in a variety of projects, sometimes as the main database MELODI and sometimes as part of a larger platform (OpenGWAS). We find creating queries with Cypher intuitive and query performance to be good. However, the integration of data into a graph is still a challenge, especially when using many data from a variety of sources. Our latest project EpiGraphDB uses data from over 20 independent sources, most of which require cleaning and QC before they can be incorporated.
