GOMYCODE

We have a graph knowledge system, therefore the number of joins are big, and this has a huge impact on performance when querying data. Also neo4j is a nosql that embraces relationship, check O'reilly graph databases e-book.

Simple, same performance as other frameworks, better suited for modularity. Components are independently implemented with business logic and presentation.

Faster, more reliable and highly scalable.

Python is easily learned, supported by the best machine learning frameworks. R is better suited for data analysis purposes.
