How FactSet used Dgraph and DQL to build a Point-in-Time Model of Financial Objects

The universe of financial objects includes Countries, Companies, Securities, Stock Exchanges, Indexes, Funds and more. These objects are related in many different ways - and many of these relationships change over time. With this universe loaded into Dgraph, our clients are able to easily explore these relationships as they exist today or at any time in the past.

Great talk! One question for the presenter: I was wondering if you ran into any issues using facets for time bounds, given the limit of only one edge per pair of nodes (Duplicating an edge with a different facet value - #2 by MichelDiz)? Eg. a case where a company’s owner changes from A to B, and then back to A, so that there are two different spans of time for the same relationship.
