Abstract: Example embodiments relate to extract graph topology from a plurality of databases. The example disclosed herein access metadata from a plurality of distributed databases. The example further access a set of predetermined rules to transform the accessed metadata into a graph description schema. The example finalizes when the visualization of the graph description schema is built.

Abstract: 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.

Abstract: Example embodiments relate to translate a GQL query into a SQL query. The example disclosed herein receives a graph query language (GQL) query, transforms the GQL query into a representation of an abstract syntactic structure of the GQL query, translates the representation of the abstract syntactic structure of the GQL query into a structured query language (SQL) query, and sends the SQL query to a relational database management system.

Abstract: Example embodiments relate to solve a graph route into a set of possible relationship chains. The example disclosed herein receives a graph route, identifies an edge expansion wildcard based on the graph route, expands the graph route into a plurality of sub-graph routes based on the edge expansion wildcard, solves the plurality of sub-graph routes in parallel into a plurality of sub-graph routes results, and joins the plurality of sub-graph routes results into a set of possible relationship chains.
