Generate SQL for your Database

Our natural language database interface allows non-technical users to obtain easy access your company's data without using a structured query language. Users simply ask for what they want in their own words. We provide an SQL output, which is used to query your database.
How it Works

Demonstration

The following three sample databases are used to demonstrate the Natural Language Database Query system. You can view the data in the databases, query the databases in natural language, see the generated SQL, and verify the results in the database. Some sample questions are included to show the variety of questions that can be handled. (Note: data in World Country database are not current.)
