This document contains SQL queries to create tables, insert records, update records, and perform aggregation functions on sample employee and student data. The key steps are: 1) Create tables to store student and employee data with various fields 2) Insert sample records into the tables 3) Update records by calculating totals, averages, and increasing/decreasing field values 4) Use aggregation functions like count, sum, avg to analyze the data 5) Display records by filtering on field values
