== Domain Model

Each *League* has multiple *Level*s like playoffs, quarter-finals etc. The levels are ordered: first is playoffs, +NEXT+ is quarter-finals, +NEXT+ is semi-finals and then the next and last one is the finals. The ordering is represented using a http://docs.neo4j.org/chunked/milestone/cookbook-linked-list.html[linked-list].

A *Player* can play for more than one team over multiple leagues but can only play for a single team in a given league. This is captured by the +PLAYED_IN_FOR_LEAGUE+ http://docs.neo4j.org/chunked/milestone/cypher-cookbook-hyperedges.html[hyperedge] between player, team and league using http://docs.neo4j.org/chunked/milestone/cypher-cookbook-hyperedges.html[hypernode] *PlayerTeamLeague* . A team can register in a new league with a different name in which case, we want to know what it was +PREVIOUSLY_KNOWN_AS+.The fact that a player had for a given team (irrespective of which league) is capture

== Domain

A product catalog is a collection of products, their categories, manufacturers with their pricing information. Products can be sold separately, included in one or more catalogs or used as substitute products

You can perform the following operations on a product:
Create, Update, Delete (Not recommended, deactivate instead), Deactivate (We should deactivate products that are no longer available instead of deleting them, because they are included in past orders, quotes, or opportunities.), Search etc.
