Report on Database System Technology: BI Reports, DBMS Codes & Demo

This report provides an overview of database system technology, focusing on Business Intelligence (BI) reports and Database Management System (DBMS) codes. It includes visual representations of data through BI reports, such as total purchase amounts by individual buyers and the total amount of car sales against months. The report also presents the SQL code used to create the database schema, including tables for buyers, cars, car owners, sales invoices, and sellers, along with constraints and relationships between these tables. Sample data is inserted into the tables to demonstrate functionality. Finally, the report briefly mentions a live demo of the database, showcasing its practical application. Desklib is a platform where you can find similar assignments and study resources.
