Abstract: A package dependencies representation and usage thereof. A data structure representing package dependencies in a computer program. The data structure comprising: a set of package instance nodes, each of which representing a different instance of a code package, wherein each package instance node comprising a unique identifier in the set of package instance nodes and a reference to a package record, wherein the package record representing a package, wherein the instance package is an instance of the package; a set of edges connecting package instance nodes of the set of package instance nodes, wherein an edge from a source node to a target node represents a dependency relationship of a package represented by the source node on a package represented by the target node.

Abstract: A system, product and process for building a package dependencies data structure. The method comprises determining a package instance identifier of the package to be processed. The package instance identifier is determined based on a unique identifier of the package to be processed and based on a unique identifier of a dependency sub-tree of the package to be processed in the package instance identifier. The package instance identifier is utilized to determine if a node representing the package to be processed exists or not. In case the node does not exist already in the data structure, the node is created and added.
