Key Topics to Focus On 🔑
To excel in study.com’s Computer Science 107: Database Fundamentals is no exception when it comes to core issues that are important to comprehend in order to succeed in the final exam. For your ease, here are the breakdowns of some of these topics along with some comparisons, real-world examples, and tables that will help for a better understanding of the topics.
Data Types in SQL: CHAR vs. VARCHAR
Understanding the difference between CHAR and VARCHAR is crucial for efficient database design.
|
Data Type
|
Description
|
Use Case
|
Example
|
|---|---|---|---|
|
CHAR
|
Fixed length, space-padded
|
When data length is consistent
|
CHAR(10) for phone numbers like 1234567890
|
|
VARCHAR
|
Variable length, no padding
|
When data length varies
|
VARCHAR(255) for addresses
|
Example: If you’re storing country codes, CHAR(2) is ideal because country codes always have 2 characters. For user comments, VARCHAR is better since the length can vary significantly.
Primary Key vs. Foreign Key
Primary and foreign keys are essential for defining relationships between tables in a relational database.
|
Key Type
|
Description
|
Purpose
|
Example
|
|---|---|---|---|
|
Primary Key
|
Unique identifier for table records
|
Ensures each record is unique
|
StudentID in a Students table
|
|
Foreign Key
|
A field in one table that links to the primary key in another table
|
Establishes relationships between tables
|
CourseID in an Enrollments table referencing CourseID in Courses table
|
Example: In a school database, StudentID as a primary key in the Students table ensures each student has a unique identifier. CourseID as a foreign key in the Enrollments table links each enrollment record to a specific course.
Normalization: 1NF, 2NF, 3NF
Normalization is the process of organizing a database to reduce redundancy and improve data integrity.
|
Normal Form
|
Description
|
Example
|
|---|---|---|
|
1NF
|
Eliminates duplicate columns and ensures each field contains only atomic values
|
Splitting full names into FirstName and LastName
|
|
2NF
|
Removes subsets of data that apply to multiple rows of a table and places them in separate tables
|
Moving CourseName to a separate Courses table
|
|
3NF
|
Removes columns not dependent on the primary key
|
Ensuring InstructorName in the Courses table does not depend on CourseID
|
Example: In a student database, normalizing ensures that each table has a specific purpose, reducing data duplication and improving integrity. For instance, splitting student contact information into a separate table linked by StudentID.
Real-World Example: E-commerce Database
Consider an e-commerce site. The database might include tables like Products, Orders, and Customers.
- Primary Key: ProductID in Products, OrderID in Orders, CustomerID in Customers.
- Foreign Key: CustomerID in Orders links to CustomerID in Customers.
- Normalization: Ensures product details are only stored in Products, while order details are stored in Orders.
With these topics and knowing more about them practically, you will be ready for the final examination in database management and future database environments. Remember these concepts, and commit them to memory, You will pass the study.com’s Computer Science 107: Database Fundamentals with ease.
