US Patent 10489360 Specifying and applying rules to data

Validation rules are specified for validating data included in fields of elements of a dataset. Cells are rendered in a two-dimensional grid that includes: one or more subsets of the cells extending in a direction along a first axis, each associated with a respective field, and multiple subsets of the cells extending in a direction along a second axis, one or more of the subsets associated with a respective validation rule. Validation rules are applied to at least one element based on user input received from at least some of the cells. Some cells, associated with a field and a validation rule, can each include: an input element for receiving input determining whether or not the associated validation rule is applied to the associated field, and/or an indicator for indicating feedback associated with a validation result based on applying the associated validation rule to data included in the associated field.
