A system and method are disclosed to facilitate exploratory data analytics for an enterprise. A storage area network, for a column-oriented relational database management system, may contain electronic records that store enterprise information. A query engine may receive, from a user via an interactive user interface, query parameters associated with the enterprise information. The query engine may then automatically generate an approximate query for exploratory data analytics using query-time sampling, the approximate query being associated with at least one of: (1) a stratified sampler with randomized row access, and (2) a hash-based, outlier aware join sampler. The approximate query may then be executed in connection with the enterprise information in the storage area network, and results of the executed approximate query may be provided to the user via the user interface.
