A data warehouse storing databases for a plurality of users, including service providers hosting data for other users of the data warehouse may implement a data exchange. A provider of data creates a listing in the exchange including metadata. A consumer browses the metadata and select a listing to add to consumed shares of the consumer. Browsing may be filtered to implement a private exchange. Adding of data may be limited by access controls requiring verification of the consumer's identity. The added data may be filtered to include only data that relates to the consumer. Sharing may be bi-directional such that a request to add a listing for first data of a provider may also reference second data of the consumer such that the first data is added to the consumed shares of the consumer and the second data is added to the consumed shares of the provider.
