Creation of scope definitions

A computer system, comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage media, and program instructions stored on at least one of the one or more computer-readable tangible storage media for execution by at least one of the one or more processors via at least one of the one or more computer-readable memories, wherein the computer system is capable of performing a method comprising:
• receiving an ownership graph comprising a first set of nodes and a first set of directional edges, wherein each of the first set of directional edges connects two nodes and indicates ownership of a first node by a second node, each node having at most one owner, the ownership graph being acyclic;
• receiving a dependency graph comprising a second set of nodes and a second set of directional edges, wherein each node of the second set of nodes in the dependency graph corresponds to a node in the first set of nodes in the ownership graph, wherein each of the second set of directional edges connects two nodes and indicates a dependency of the first node on the second node, the dependency graph being acyclic, wherein each node of the second set of nodes in the dependency graph with an incoming edge is a decision node;
• for each decision node in the dependency graph, automating computer code to implement a respective decision by:
• an enumerator builder arranged to automatically create a respective enumerating variable declaration for each node in a path from an owner node of a current node to a root node in the ownership graph, by the one or more processors, wherein the respective enumerating variable declaration comprises a variable name, a variable type, and a path expression specifying a variable range;
• an informational-scope builder arranged to automatically create a respective accessing variable declaration for each owner node in the dependency graph of the current node, by the one or more processors, wherein the respective accessing variable declaration comprises a second variable name, and a second path expression specifying one or more values for a variable;
• automatically generating a cumulative business decision for the root node, by the one or more processors, based on the created enumerating variable declarations and the created accessing variable declarations;
• and
• automatically updating items in a digital shopping cart associated with at least one node in the path from the owner node of the current node to the root node in the ownership graph by the one or more processors based on the automated decisions.

A computer program product for controlling a system comprising a processor, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by the processor to cause the processor to:

• receive an ownership graph, wherein the ownership graph comprises a first set of nodes and a first set of directional edges, wherein each of the first set of directional edges connects two nodes and indicates ownership of a first node by a second node, each node having at most one owner, the ownership graph being acyclic;
• receive a dependency graph, wherein the dependency graph comprises a second set of nodes and a second set of directional edges, wherein each node of the second set of nodes in the dependency graph corresponds to a node of the first set of nodes in the ownership graph, wherein each of the second set of directional edges connects two nodes and indicates a dependency of the first node on the second node, the dependency graph being acyclic, wherein each node of the second set of nodes in the dependency graph with an incoming edge is a decision node;
• for each decision node in the dependency graph, automating computer code to implement a respective decision by:
• automatically creating a respective enumerating variable declaration for each node in a path from an owner node of a current node to a root node in the ownership graph, wherein the respective enumerating variable declaration comprises a variable name, a variable type, and a path expression specifying a variable range;
• automatically creating a respective accessing variable declaration for each owner node in the dependency graph of the current node, wherein the respective accessing variable declaration comprises a second variable name and a second path expression specifying one or more values for a variable;
• automatically generating a cumulative business decision for the root node, by the processor, based on the created enumerating variable declarations and the created accessing variable declarations for each automated decisions;
• and
• automatically updating items in a digital shopping cart associated with at least one node in the path from the owner node of the current node to the root node in the ownership graph by the processor based on the automated decisions.
