Counting and displaying occurrences of data records

摘要

Occurrences of data records in a non-relational database are counted by first selecting rows of data records. A counter field is created and appended to the selected rows. The counter field is weighted with a fixed value which may be different for different selected rows. A summation is performed on the weighted counter fields to count and subsequently display occurrences of data records. Various counts may be dynamically displayed in response to selection of sort columns in a view of the selected rows of data records.
