Improving Database Design through Normalization
Continue improving the database (tables) you designed in SLP 2. Here are your tasks:
Discuss whether the tables you designed in SLP 2 (in the previous module) have satisfied 1NF, 2NF, and 3NF. Explain why or why not.
Make changes if the tables do not meet the requirement of the 3NF.
Write Oracle SQL statements to create the tables you have designed, and populate the tables with data.
Note: Use the materials in the background reading for your assignment:
Wang, W. (2017). Introduction to SQL (DDL).
Note: voice-over presentation covering the set of Oracle commands used to create and modify the structure of tables. (Remember that narrated presentations take a little longer to download.)
Wang, W. (2017). Introduction to SQL (DML).
Using data manipulation language (DML) to work with data.
Note: Oracle commands that “ask” database questions.
Wang, W. (2017). Add primary key and foreign key to tables using Oracle SQL.
Note: how to add primary and foreign keys.
Wang, W. (2017). Writing a query using one or more tables.
Note: techniques used when requesting information from a single table, as well as tables connected to one another.
Please note that since you are the designer of this database, you need to create data to fill in the tables. No need to create a lot of data; 5-10 records of data in each table are sufficient.
