SQL

This course provides a comprehensive introduction to the language of relational databases: Structured Query Language (SQL). Topics covered include: Entity-Relationship modelling, the Relational Model, the SQL language: data retrieval statements, data manipulation and data definition statements.

All interactive reading problems involve the use of "live" SQL. Homework will be done using databases running in MySQL which students install on their machines. Students develop a real-world database project using MySQL during the course.

SQL Training Course Objective:

• Learn structured query language (SQL) to an intermediate/advanced level.
• Be able to write data retrieval queries and evaluate the result set.
• Be able to write SQL statements that edit existing data.
• Be able to write SQL statements that create database objects.
• Understand the structure and design of relational databases.
• Understand the importance and major issues of database security and the maintenance of data integrity.

Why This Course is Required:

SQL may be quite an old computing language, but it is still as relevant as ever. This is why you need to learn SQL if you are going to work with data. In fact, in the recent numbers found, it was found that SQL is still the most commonly used in data science. This puts the language ahead of even R or Python!
