Abstract
Key values can be defined at design time (e.g. in a DTTI object) using character strings that include wildcard characters that define multi-dimensional key ranges. Wildcard characters can designate that a single variable character is to be inserted or that a range from zero to multiple characters can be inserted. The use of wildcards can make checks for key intersection non-trivial. During run time, the key values to be accessed from one or more tables are evaluated, and the operation proceeds. An error can occur if the presence of one or more wildcards in two key value strings used in an aggregation operation result in an overlap such that a same record is included more than once.
