One of the most promising areas in the world of NoSQL - graphs based storage and processing system which based on the theory of graphs. Neo4J - is, perhaps, the most popular Graph database at the moment. It provides high performance data storage and working with graphs, using various Java APIs and declarative query language Cypher.
Adobe, Cisco, classmates.com, Deutsche telecom and many others are using Neo4J.

i. For each weak entity type, create a
corresponding relation that includes all the
simple attributes
ii. Add as a foreign key all of the primary key
attribute(s) in the entity corresponding to
the owner entity type

Foreign Key
i. Choose one relation as S, the other T
Better if S has total participation (reduces
number of NULL values)
ii. Add to S all the simple attributes of the
relationship
iii. Add as a foreign key in S the primary key
attributes of T

A. Multiple relations – subclass and superclass
Usually works (assumes unique id at parent)
B. Multiple relations – subclass only
Should only be used for disjoint
C. Single relation with one type attribute
Only for disjoint, can result in many NULLs
D. Single relation with multiple type attributes
Better for overlapping, could be disjoint
