Introduction to SQL
On 11/3/2022, through the 50-minute live webinar held by Dr. Vazi from the NR Computer Learning Center. I learned more about how to write SQL statements for data analysis. Including topics such as Relational Database Basics, Relationships, Datatypes, Primary & Foreign Keys, Introduction to SQL Statements, Database Manipulation Language (DML), SELECTing All Columns and Rows, SELECTing Specific Columns or Rows, Using the WHERE Clause and Operator Symbols, Checking for a NULL value, Using BETWEEN, IN, LIKE and NOT Operator, Checking Multiple Conditions using AND and OR and Using Common Math Functions. Moreover, this further connects to the MIS: Data Analytics and Turning Number into Visualization courses that I have once taken.
