摘要： Querying a data set formed from a version of primary data and secondary data is facilitated. First and second versions of primary data are stored in a primary data version store. Secondary data is received. The secondary data is stored in a secondary data store. A query language statement is received. The query language statement is executed by selecting query results from a data set that includes the secondary data and elements of the first version of primary data not inconsistent with the secondary data.

摘要： Technologies are described for facilitating querying a data set formed from a version of primary data and secondary data. First and second versions of primary data are stored in a primary data version store. Secondary data is received. The secondary data is stored in a secondary data store. A query language statement is received. The query language statement is executed by selecting query results from a data set that includes the secondary data and elements of the first version of primary data not inconsistent with the secondary data.
