Max Neunhöffer from ArangoDB shows an use case for multi-model NoSQL databases on Strata + Hadoop World 2015 in London. Join his Session on 6th of May.
We describe a case study in aircraft fleet management, where we needed a database that would store data about all the different parts and subunits of an aircraft. A single aircraft already contains some 6,000,000 parts, not counting components.
The particular structure of the queries arising naturally from day-to-day processes quickly led to the insight that no single data model was sufficient to ensure satisfactory performance. Whichever data model we tried, there was always at least one important query that would either take ages to complete or be unbearably complicated, or indeed both.
