Abstract

A method and system are described for managing data quality. An example method may include obtaining a first data stream interval including a first group of data items and a first aggregated data quality value associated with a quality of obtaining the first group, each data item including data attribute values, each data quality item including data quality attribute values associated with one of the data items. The first aggregated data quality value, a first indicator associating the first aggregated data quality value with the first group, and the first group may be selected. The first group and the first indicator may be stored in a user table of a database. A data quality table associated with the user table may be determined based on an entry in a system table. The first aggregated data quality value and the first indicator may be stored in the data quality table.
