Read Requirements, Relational or non-Relational Data, Complex Join Queries

Our data is highly structured and requires referential integrity or not required for relationships that is dynamic and frequently changes ?

▪ Should it work with complex queries, table joins and run SQL queries on normalized data models or Retrieve data operations are simple and performs without table joins ?

▪ Deployments, Centralized or De-centralized Structure

Do we deployed to large and one or few locations with centralized structure ? or Do we need to deploy and replicate data across different geographical zones ?

▪ High Performance Requirements

Do we need to achieve fast read-write performance ?
