Processing queries using explicitly defined relationships and inferred relationships of data objects

A non-transitory machine-readable medium having instructions stored therein, which when executed by a processor, cause the processor to perform operations for managing use of data sources of a distributed system, the operations comprising:

• obtaining a data operation request;
• identifying a template based on the data operation request;
• generating a refined dependency graph for the data sources by at least:
• extracting database schemas from databases of the data sources, each of the data sources being a computing device, the database schemas comprise data objects stored in the databases, and each of the data objects being a data structure that stores data;
• extracting all of the data objects from the data schemas;
• and
• generating inferred relationships between the data objects, the inferred relationships supplement explicitly defined relationships between the data objects that are already defined in the database schemas;
• populating the template using the refined dependency graph to obtain a processable query, the refined dependency graph comprising:
• a plurality of nodes based on the data objects,
• a first plurality of edges between the nodes, the first plurality of the edges being based on the explicitly defined relationships between the data objects, the first plurality of the edges having different edge types based on a similarity level between the nodes connected by the first plurality of edges, and
• a second plurality of the edges between the nodes, the second plurality of the edges being based on the inferred relationships between the data objects;
• and
• processing the processable query using a query servicing entity to provide one or more computer implemented services to complete the data operation request, a first level of accuracy of the one or more computer implemented services provided to complete the data operation request using both the inferred relationships and the explicitly defined relationships being higher than a second level of accuracy associated with using only the explicitly defined relationships without the generating of the refined dependency graph to generate the inferred relationships.
