1970 E.F. Codd initiated a significant transformation with his paper 'A relational model of data for large shared data banks, Communications of the ACM, Volume 13, Issue 6 (June 1970),' which laid the foundation for the widely utilized database query language SQL that we see today.
This application provides a demonstration of fundamental and derived operations, including:
- Sample queries for SQL92 and SQL86/89,
- The query results, and
- Accompanying descriptions.
In addition to this, users can access the SQL test script employed to generate the examples.
This application serves as a valuable resource for individuals new to the field of databases as well as those transitioning from using SQL86/89 queries for more than two decades and are looking to adapt to SQL92.
