Importance of Database design in real world applications

Steps in solving a database design homework
- Find out the purpose of Database - It would help you for all the leftover steps.
- Identify the Information Required to Store - Identify the information required to store in the database such as username, password, email, name, date of birth in case of registering user.
- Design Tables required for storing data - Identify the information which is related to an entity and make it a table such as User_account, user_profile.
- Design Columns in the table - Identify which set of data is to be stored in which table. Each item becomes a field and is displayed as a column in the table. For example, username, email, and password become columns of user_account, name and date_of_birth become columns of user_profile.
- Identify primary keys - Each row has to identified uniquely so assign a primary key to a field which would be unique. For example, userid is primary key for user_account table.
- Desing Relationship between Tables - Identify the columns which can be related to another column of the different table to maintain consistency. For example, user_account and user_profile table would be related with column user_id in both the tables.
- Review and Refine your design - After reviewing your database design, create the actual database and tables. Insert some data into the tables and check the correctness of the result fetched. If the result is not correct, redesign your database and recheck for the result.
- Apply the normalization rules - Apply Normalization in the database to make the database design robust.
