The Ch07_LargeCo database stores data for a company that sells paint products . The company tracks the sale of products to customers . The database keeps data on customers (LGCUSTOMER), sales (LGINVOICE), products (LGPRODUCT), which products are on which invoices (LGLINE), employees (LGEMPLOYEE), the salary history of each employee (LGSALARY_HISTORY), departments (LGDEPARTMENT), product brands (LGBRAND), vendors (LGVENDOR), and which vendors supply each product (LGSUPPLIES). Some of the tables contain only a few rows of data , while other tables are quite large : for example , there are only eight departments , but more than 3300 invoices containing over 11000 invoice lines . For Problems 28-55 , a figure of the correct output for each problem is provided . If the output of the query is very large , only the first several rows of the output are shown .
