Complex approach of data with graphs and other tools

A way to represent and manage "big data" is to use a graph database. Such a database uses graph structures for semantic queries with nodes, edges and properties to represent and store data locally indexed.
A graph database is essentially a collection of nodes and edges. Each node represents an entity (such as a person or business) and each edge represents a connection or relationship between two nodes.
Every node in a graph database is defined by a unique identifier, a set of outgoing edges and/or incoming edges and a set of properties expressed as key/value pairs.
Each edge is defined by a unique identifier, a starting-place and/or ending-place node and a set of properties. Graph databases are well-suited for analyzing interconnections, which is why there has been a lot of interest in using graph databases to mine data from different media. CIGESMED is testing them in a global ecology framework (graph transversal).
In CIGESMED we will complement this approach by data mining in order to reveal new data patterns which are not accessible through classical approaches.
