Abstract

In the context of a constraint-based or rule-based model, in which nodes are interrelated by constraints, rules, and conditions, addition of and changes to nodes need to be validated against relevant constraints. A mechanism is provided for performing such validation without loading the entire configuration, which includes a set of constraints and a set of node variables. In response to an intent to modify a node, a subset of the set of constraints is determined, which includes all constraints that restrict the intent to modify. Further, a subset of the set of node variables is determined, which includes all node variables that may have values that affect whether any of the subset of constraints is violated. A subset of node variable information is loaded into volatile memory, which includes only information about the subset of node variables, rather than information about all of the nodes of the model.

Dependent claims

A method for managing an instance of a model, wherein the instance includes a set of nodes with associated node variables and a set of connection constraints, the method comprising the computer-implemented steps of:

receiving an intent to modify the instance, wherein the intent to modify specifies a first node of the set of nodes;
loading into volatile memory information associated with said first node;
determining, based at least on said information associated with said first node, a first subset of said set of connection constraints, wherein said first subset of connection constraints includes all connection constraints that restrict said intent to modify, and wherein said first subset of connection constraints includes fewer constraints than said set of connection constraints;
determining, based on said first subset of connection constraints, a first subset of node variables that are associated with nodes of said set of nodes, wherein said first subset of node variables includes all variables that may have associated values that affect whether any constraint of said first subset of connection constraints is violated;
and
loading into volatile memory a first subset of node variable information, wherein said first subset of node variable information includes only information about said first subset of node variables.
