Example embodiments relates to method and systems to infer graph topologies. A computing device for inferring a graph topology, comprises a physical processor that executes machine readable instructions that cause the computing device to process a set of unclassified tables. For each table the computing device determines a primary key comprising a set of columns of a table being analyzed, determines a set of foreign keys, each foreign key comprising a column of the analyzed table, and identifies a parameter based on the analyzed table, the primary key and the set of foreign keys. The parameter may comprise a node identification, a set of node attributes, a set of edges without attributes, a set of edges with attributes or a set of edge attributes. The computing device can cause the display of the graph topology based on the processed set of unclassified tables.
