These dml statements populate the tables with sample data that satisfies the many to many relationship between students and courses. the courseenrollment table records the enrollment of students in various courses, with grades assigned to each enrollment. Any time you add a new column to a table, ask yourself whether the data it represents defines that table. if you answer no, then store the data in a different place (e.g. lunch period does not fit within students, so it will have to go in a different table, such as schedule). It is important to understand and design relationships among tables in a relational database like sql server. in a relational database, each table is connected to another table using the primary foreign key constraints. In sql, the create table statement is used to create tables. in this tutorial, we'll learn about creating tables in sql with examples.
