1. A system configured to facilitate performance of quantitative analysis, the system comprising: a computer system comprising one or more processors programmed to execute one or more computer program instructions which, when executed, cause the computer system to: store, in non-transitory storage media, a graph comprising nodes used in the performance of calculations, wherein the graph nodes comprise at least one node representing a calculation object, wherein the graph nodes are identified by keys that comprise node identifiers and contextual label collections, obtain a result calculated using a first calculation object represented by a first node of the graph nodes, wherein the first node is identified by a first key that comprises a first node identifier and a first contextual label collection; generate a second key for identifying a second node that represents the obtained result such that the second key is generated to include a second node identifier and a second contextual label collection, wherein the second contextual label collection includes one or more contextual labels of the first contextual label collection based on the first calculation object being used to calculate the obtained result; assign the second key to the second node for identifying the second node; and store, in the non-transitory storage media, the second node as part of the graph.
