Embodiments are directed to managing data using network computers. A data model that includes a plurality of data objects, a plurality of data relationships, and a plurality of shortcuts may be provided. If portions of the data model being are selected in the user interface for removal from the data model further actions may be performed, including: determining edges and nodes associated with the portion of the data model; determining critical edges that may be associated with nodes included in the portion of the data model; traversing the data model based on the critical edges; determining critical shortcuts based on the traversal and shortcut specifications that may match the critical shortcuts; modifying the data model by deleting each critical shortcut unmatched to the shortcut specifications and deleting the selected portions of the data model along with the associated plurality of nodes and edges; or the like.

Determining shortcut relationships in data models

Embodiments are directed to managing data using a network computers. A hierarchy model that includes edges that represent dependency relationships between fields may be generated. In response to a query for determining values of metadata associated with an anchor field performing further actions, including: traversing the hierarchy model upwards from the anchor field based on the query, and in response to visiting field nodes in the hierarchy model, collecting the values of the metadata that correspond to the visited field node and terminating the traversal based on a type of the query; in response to visiting a calculation node, terminating the traversal of the hierarchy model associated with the visited calculation node; and in response to visiting a flow node that is dependent on two or more other nodes, terminating the traversal of the hierarchy model. The collected metadata may be provided in a response to the query.
