This database course teaches you everything you need to know about databases!
This course is divided into 4 sections - watch them in sequence:
Section 1. Introduction to Databases (Very Basic)
Section 2. Design Phase (Practical Theory)
Section 3. Physical Phase (SQL) with lots of exercises - You will practice on Oracle platform
Section 4. Five Real-world Hands-on Projects (Fast paced. You have to watch section #2 and section #3 first)
Through out the course, you'll receive 50 downloadable resources such as exercises and projects to help you follow along with me.
With no experience required, this database course will take you from a
complete beginner to a confident and competent database developer who is
able to productively contribute to projects and achieve the results you
Feel free to ask me questions! I'll be happy to help you out.
Database classes are expensive. You pay for Hotel + Food + Travel + Tuition fees! A combined Relational Database Developer (RDBMS) Class + SQL Query Writing Course + Advanced SQL Writing Class quickly adds up to more than $5000. You are getting this course for LESS than a fraction of that cost!
Important Notice: this course is NOT part of udemy promotions program and not subject to any udemy discounts.

Warning: this database course is quite intensive and you have to watch them in sequence unless YOU HAVE DATABASE EXPERIENCE. I broke the course into many short videos to help beginners understand the course.

Reminder: first name, last name, and email is not a Candidate Key because we can reduce the key to email
Superkey is every possible key out there the ones that can be reduced
and the ones that cannot be reduced. The keys that can't be reduced get
elected as Candidate keys and then ONLY one of those candidate keys can
be selected as a primary key. For example, "First Name, Last Name, Email" is a superkey but cannot be a Candidate Key. However, Email is a Candidate Key because Email is unique enough to identify a record without the need of first name and last. In short, First Name, Last Name, Email is superkey not a candidate key.
Note: In the first five seconds, the voice sounds as if it got cut in half when in fact its not. This problem was caused by audio issues.
Important Note: Fourth Normal Form is listed under lecture 124 by the very end of the Physical Phase; I didn't create appendix section. Why did I move 4NF to lecture 124? 4NF+ is more theortical and may confuse you and distract you if I demonstrated it right after 3NF. Also, 4NF and above are supplementary and not mandatory.
You can find lots of free youtube tutorials on how to design ERD on Microsoft Visio. For the time being, don't worry about designing ERD on MS Visio because it's luxury rather necessity. Anyhow, if still interested in MS Visio, here is few resources:

From 1:40 to 1:50 there was a video editing issue that may cause confusion:
total salary sum of department 90 is 88,000 NOT 58,000
In this lecture, I added the keyword "CONSTRAINT" when assigning primary key and foreign key. Note that the "CONSTRAINT" keyword is optional. The fact is whenever you create a constraint such as primary key or foreign key, the Oracle system automatically
gives each constraint a unique name implicitly; so, rather than letting
Oracle assigning the constraint name automatically, you can use the keyword "CONSTRAINT"
as shown in this lesson. How can assigning CONSTRAINT name help you? It
helps you when you decide to drop the primary key or foreign key from a
table! How would you identify the PK and FK to be dropped? You identify
them through the CONSTRAINT name.
Comments regarding this video tutorial:
You do not necessarily have to enclose an alias with double quotation. The only time you are obliged to wrap double quotation on an alias is when the alias has spaces, such as First Name; you will have to write as "First Name". Also, the keyword AS is optional. You don't have to use it to name an alias.
Congratulations for the excellent effort you put in!
