Database Design and Use Group Assignment
Assignment Description -
In this assignment you will use your normalized "City Jail" database you have created in your assignment one. You will form a group (2-3 students) and implement your designed City Jail database using Oracle SQL developer 12c. You will also perform different types of SQL queries on it to sharpen your SQL skills to implement and manage the database.
Assignment Tasks need to be executed -
-Discuss with in your group to find the best normalized "City Jail" database design to implement in Oracle database.
-Write down all the SQL statements require to construct the entire City Jail database. Execute all SQL queries in Oracle SQL developer 12c to implement the "City Jail" database in Oracle 12c. The CREATE TABLE statements should be created as a group.
-Execute the following queries individually and provide your answers:
Group member One:
- Insert 5 different entries in each table. You can create fictitious data to create those entries.
- Add a column named Mail_flag to the CRIMINALS table. The column should be assigned a data type CHAR (1).
- Set the Mail_flag column to 'N' for all criminals who don't have a street address recorded in the database.
- Change the phone number for a criminal to 7225659032.
- Remove a specific criminal from the database. Make sure you remove all the associated information relevant to that criminal.
