Hello from Tom - I'm an HR Systems consultant in the UK

Hello everyone. I'm a complete novice not a techy but want to develop a database to map the relationships between the different types of functionality and the different HR Systems' vendors (at its simplest Function A [is provided by] Vendors 1,2,3...]. The goal is to provide visitors to a web site with the means of finding those vendors that provide the functionality they are looking for. I found out about graphs and Neo4j from a friend who has built a graph database to support his much more complex business.
