Hands-on video tutorials for SAP HANA Graph

[PhilipMugglestone]

Hi,

Graph processing is a hot topic right now - especially since it enabled investigative journalists to uncover the world's biggest offshore banking scandal. Commonly referred to as the "Panama Papers", graph processing allowed investigators to sift through a 2.6 terabyte morass of data incorporating 1,400 offshore tax havens and 100,000 companies in order to reveal hitherto unknown connections.

Did you know that SAP HANA includes a native in-memory graph processing capability?

To quotemichael.eacrett's recent blog covering what's new in SPS 12:

"SAP HANA graph data processing is now generally available, providing the processing capabilities help customers extract deeper insights from hyper-connected data and their relationships. SAP HANA includes a graph engine with built-in graph algorithms (neighborhood search, shortest path, strongly connected components, pattern matching) to find connections without manually creating complex JOIN statements. It also introduces a Property Graph model with flexible schema, which enables users to traverse relationships without the need for predefined modeling.  It also comes with a graph viewer tool (for quick visualization and dynamic interaction (i.e. change algorithm parameters) with graph data real-time, and a graph modeler tool that is (integrated with SAP Web IDE for SAP HANA to create and consume graphs visually instead of via SQL or SQLScript."

So you're raring to get going with graph processing but don't know where to start? Well that's where the SAP HANA Academy comes in...

With nearly two hours of hands-on video content, the new SAP HANA Academy playlist covering SAP HANA graph data processing provides tutorials that cover everything from a chalkboard overview and introduction, to downloading, installing, and working with the graph viewer tool, to enabling graph processing inside calculation views via the graphical modeler based on XS Advanced and SAP Web IDE for SAP HANA.
