Consider the ER diagram illustrated in the following figure. Convert the ER diagram to relations and write SQL DDL statements for creating the tables for those relations. Pick suitable data types for each attribute. For string attributes pick reasonable lengths. Include the appropriate constraints (domain, primary key, foreign key, UNIQUE, and NULL constraints) in your SQL DDL statements. Note: For the one-to-many binary relations, combine the relation with the many side.

PLZ help with the following: Translate your ER diagram into a relational schema in the form of SQL DDLs. Choose appropriate data types for each attribute and include primary key and foreign key constraints, Check and Not Null constraints. Normalize the relations to 3NF.
In SQL, foreign key constraints can reference only the primary key attributes ofthe referenced relation or other attributes declared to be a superkey using theunique constraint. As a result, total participation constraints on a many-to-manyrelationship set (or on the “one” side of a one-to-many relationship set) cannotbe enforced on the relations created from the relationship set, using primarykey, foreign key, and not null constraints on the relations. Explain why
The task is to write SQL statements to define tables for the corresponding relations. Make sure that the data and size for each attribute is appropriate. An example of this is how the data type DATE is a better choice than a string data type for the attribute dayOfGame. Additionally, SQL statements to load data into each table based on the given records must be written down. Goals: Write SQL statements to remove tables from the database. Due to foreign key constraints, the sequence of removing tables should be in the reverse order of creating tables. Write SQL statements to define the three tables in the database showcased in the image. Each table should exactly have one PRIMARY KEY. The PRIMARY KEY may have more than one column. Besides the PRIMARY KEY, the table GameStats has two FOREIGN KEYs. Write SQL statements to display the structure of the newly built tables. Write SQL statements to load records into the tables. Add one more record for each table.
Consider the relational schema shown in Figure 8.8. Give a schema definition in SQL corresponding to the relational schema but using references to express foreign-key relationships.
