Static analysis techniques, such as abstract interpretation, can be extended to query languages in a database.
This allows for the development of sound approximation techniques to analyze and understand the behavior of queries.
By abstracting the relational database systems, it becomes possible to apply these techniques for various purposes, including security-related tasks like fine-grained access control and watermarking.
