A Model-Driven Approach to Generate Schemas for Object-Document Mappers
IEEE Access, 2019 Many actual NoSQL systems are schemaless, that is, the structure of the data is not defined beforehand in any schema, but it is implicit in the data itself. This characteristic is very convenient when the data structure suffers frequent changes. However,
