A computer-implemented method for performing constraint analysis, the method comprising: receiving a request from a user to instantiate a data object, the data object comprising a plurality of features, at least a portion of the plurality of features being subject to one or more constraints of a set of constraints; receiving user input selecting one or more values for one or more of the features; receiving a request to determine whether a set comprising two or more of a domain, a value, or a combination thereof are valid or invalid with respect to the set of constraints, said domain, value, or a combination thereof representing said user selected values for one or more of the features; receiving a table representing the set of constraints, the table comprising a plurality of rows, each row having a row ID, and a plurality of columns, each column having a column ID; receiving a domain for at least a first column of the plurality of columns, the domain comprising a plurality of values that represent valid values for the at least a first column; receiving a domain or a single value for at least a second column of the plurality of columns, the domain or single value representing one or more valid values for the at least a second column; sequentially analyzing the rows of a first selected column of the plurality of columns to determine a first row of the plurality of rows having a value matching a value, or being within a domain, of the first selected column; setting a putative minimum index of a first valid tuple for the table as the index of the determined first row; analyzing a value of a second selected column at the determined first row to determine if the value matches a value, or is within a domain, of the second selected column, wherein the putative minimum index is increased if an invalid value is found; determining a value for a minimum index of the first valid tuple of the table as the putative minimum index of a row of the plurality of rows where column values for the row match a value, or are within a domain, of the respective columns, or determining that the table does not comprise a valid tuple; and sending an indication of whether the set of constraints is violated or entailed; determining that the domain associated with at least one column of the plurality of columns has changed or the at least one column has been assigned a single value; and starting at the minimum index of the first valid tuple, carrying out at least the sequentially analyzing, analyzing, and determining for at least the at least one column. receiving a request from a user to instantiate a data object, the data object comprising a plurality of features, at least a portion of the plurality of features being subject to one or more constraints of a set of constraints;
