1. A computer program product comprising:
one or more computer readable storage media and program instructions collectively stored on the one or more computer readable storage media, the program instructions collectively stored comprising:
program instructions to control access to sampled data of a database, the sampled data being a sampling of selected data in which certain selected data is omitted from the sampled data, and wherein the program instructions to control access to the sampled data include:
program instructions to obtain, via a database management system executing within a computing environment, a request to query the sampled data of the database;
program instructions to determine, using the database management system and based on the request, whether the sampled data of the database is to be accessed by the query, wherein the program instructions to determine whether the sampled data of the database is to be accessed use domains defined to control access to the sampled data, the domains including a query domain and a data domain, the program instructions to determine whether the sampled data of the database is to be accessed include program instructions to check the query domain defined for the query with the data domain defined for the sampled data, wherein the query domain identifies a selected domain with which the query belongs and the data domain identifies a chosen domain with which the data belongs; and
program instructions to access the sampled data, via the query, based on the checking of the query domain and the data domain indicating that the sampled data is to be accessed.
