CoreData vs Jugglingdb: What are the differences?

Developers describe CoreData as "A framework that is used to manage the model layer objects in your application". It is an object graph and persistence framework provided by Apple in the macOS and iOS operating systems. It allows data organized by the relational entity–attribute model to be serialized into XML, binary, or SQLite stores. It provides generalized and automated solutions to common tasks associated with object life cycle and object graph management, including persistence. On the other hand, Jugglingdb is detailed as "Multi-database ORM: redis, mongodb, mysql, sqlite, postgres, neo4j, memory". JugglingDB(3) is cross-db ORM for nodejs, providing common interface to access most popular database formats. Currently supported are: mysql, sqlite3, postgres, couchdb, mongodb, redis, neo4j and js-memory-storage (yep, self-written engine for test-usage only). Jugglingdb also works on client-side (using WebService and Memory adapters), which allows to write rich client-side apps talking to server using JSON API.

CoreData and Jugglingdb belong to "Object Relational Mapper (ORM)" category of the tech stack.
