SQL & Database Design A-Z™: Learn MS SQL Server + PostgreSQL

via Udemy


Learn Both SQL Server & PostgreSQL By Doing. Enhance Your Data Analytics Career With Real World Data Science Exercises

What you'll learn:
  • Create basic SQL Queries
  • Create advanced SQL Queries
  • Create Left, Right, Inner and Full Outer joins
  • Create new tables, alter existing tables in Databases
  • Normalize Databases
  • Understand database design
  • Understand first, second and third normal form schemas

Are you interested in a career in Data Science or Data Analytics?

In that case, inevitably you are going to encounter databases in your work.

But how do you interact with databases?

The answer is simple:SQL

SQLstands for Structured Query Language and this is one of the main tools used to organize databases, input data into them and extract it on request.

In this course you will learn how to create queries in a popular variation of SQLcalled PostgreSQL.

And even if at your workplace you are using a different variation (e.g. Oracle, SQLServer or MySQL), you will find thatthe skills you learn in this course are easily transferable.

But there are many SQLcourses out there, so the question is:

What makes this course stand out?

The unique advantage of this course is that in addition to learning SQL you will also master the concepts of Database Design.

We will cover off topics such as:

- OLAPvs OLTP databases (Online Analytics Processing &Online Transaction Processing):you will understand exactly how and why the designs of these two types of Databases differ

- Normalization of Databases:we will show you the theory behind normalization ANDtogether we will practice how to normalize a Database step-by-step

Why is that important?

Knowing how databases are designed is not a compulsory skill to have for a Data Scientist / Analyst. However, it's a HUGEadded benefit.

These skills will allow you to better interact with databases and derive results and extract insights from your datafaster.

This course is designed with the Data Scientists and Analystsin mind, so if you want to propel your Data Science career, then this course is for you!

We look forward to seeing you inside,
