Described herein is a framework for providing and securing data access by external users. In accordance with one aspect of the framework, an external schema is generated to pair with an existing company schema in a database. The company schema may own data stored in the database. One or more access-control views that expose one or more subsets of the data may further be generated. The external schema may be granted access to the one or more access-control views. Synonyms may be created to rename access-control views, so that the synonyms share common names with corresponding database objects accessible via the company schema. External users may then access the data visible to them via the synonyms that are used to alias the access-control views.
