Abstract: An extensible object model system for maintaining extensible object models representing operational systems enables saving and re-using of searches of the models by maintaining a database of search objects representing types of search operations associated with the extensible object models. Search selection input and/or parameter selection input are received via a search selection interface with respect to a particular extensible object model, the search selection input indicating a selected search object and the parameter selection input indicating values corresponding to input parameters required by the selected search object.

Abstract: A method includes obtaining a relational model, the relational model comprising a plurality of nodes and a plurality of links, each of the links of the plurality of links connecting one or more nodes of the plurality of nodes, and each link corresponding to a relationship between a first node and a second node, receiving a request to update the relational model, the request comprising information corresponding to an added and/or edited first node, determining a first probability that the first node is in a relationship with a second node and a second probability that the first node is in a relationship with a third node, and updating the relational model to include the relationship between the first node and the second node at the first probability and the relationship between the first node and the third node at the second probability.
