This document shows the steps taken to connect to a MySQL database named "akademik" and perform various operations like creating tables, inserting data, running queries, and correcting errors. The key events are: 1. The user connects to the MySQL database server and selects the "akademik" database. 2. Several tables are created to store student, course, and grade data and data is inserted. 3. Queries are run to view the data and calculate grade point averages, though some errors are encountered and corrected.
