The volume of data available is huge and increasing daily. Structured Query Language -SQL (pronounced as sequel) is the standard language used to communicate and interact with data stored in relational management database systems like Microsoft  SQL Server Oracle, PostgreSQL,MySQL etc. Different database management systems have their own proprietary  version of the SQL language  but they all conform to using some commands in SQL the same way.   Microsoft SQL Server's version of SQL is known as Transact-SQL  (T-SQL). In this course you will learn the basics of the SQL language and Transact-SQL since  both use certain commands in the same way. What You will learn includes: Installing SQL Server Install SSMS Basic Database  Concepts Creating Database Creating Table Creating Views Creating stored procedures Reading data from a database Updating database records Backing up database Deleting Records Truncating Table Dropping Table Dropping Database Restore Database

From the creator of SAP LSMW Made Simple, comes another introductory course. Follow the instructor as he shows you step-by-step on how to properly execute queries in a database using SQL. This course assumes you have no prior knowledge of SQL. The lectures are organized in an 'easy-to-learn' format so as to make learning fun.

It is becoming ever more important that companies make data-driven decisions . With big data and data science on the rise, we have more data than we know what to do with. One of the basic languages of data analytics is SQL, which is used for many popular databases including MySQL , Postgres , SQLite , Microsoft SQL Server , Oracle , and even big data solutions like Hive and Cassandra . I’m going to let you in on a little secret. Most high-level marketers and product managers at big tech companies know how to manipulate data to gain important insights. No longer do you have to wait around the entire day for some software engineer to answer your questions - now you can find the answers directly, by yourself, using SQL! In this course, SQL for marketers , we'll start from the basics - installing SQL onto your Mac, Linux, or Windows machine and explaining what a relational database is. Next, we'll look at basic tasks like creating tables and loading data into those tables. We will look at a wide variety of SQL commands and I will show you how to speed things up using indexes . Once you know all the SQL commands we will start doing advanced examples - answering questions marketers and business people often have, like where are customers dropping off in our sales funnel ? And which of our locations has the highest revenue ? In the last section, we'll do Advanced SQL queries on Spark , the big data framework that is the successor to MapReduce and also runs on top of Hadoop . I will teach you how to install Spark, create a cluster very quickly on Amazon EC2 , and run SQL queries, allowing you to apply everything you learned up until this point in a big data environment. Do you want to know how to optimize your sales funnel using SQL, look at the seasonal trends in your industry, and run a SQL query on Hadoop? Then join me now in my new class, SQL for marketers!

WHAT SOME OF MY STUDENTS SAY ABOUT THE COURSE: "It was a great course and very easy to follow especially for someone who had no experience in SQL. The examples given were simple and Dr. Cas breaks it down really well so you can understand better. She walks you through all the different queries thoroughly and also writes down some helpful hints if you get stuck. She was also very attentive when I got stuck on one of the challenges and reached out to her one late night. She helped me understand it better by giving me more guidance and helped me think outside the box. Overall, this was a great course to take and now I have another skill under my belt all thanks to Dr. Cas! Thanks for everything!" - Karla Flores , Senior Financial Analyst, Adobe (California, USA) "Excellent course and terrific inputs about every query. Majority of the job interviews that I appeared before this course had questions on SQL and I used to mess it up since I didn't have my basics strong.This course not just helped me with the basics but also with the advanced concepts. It's absolutely brilliant. I just feel completely charged up to attend any DS interview where SQL is a skill set that is asked. My motivation was not to give any chance to the interviewer/recruiter is to not provide any more opportunities to them to reject me and this helped me at least get to that stage. Rest of the outcome depends on the practice that I do. Only need some practice on the Data Cleaning section else I think I am prepared from an interview standpoint. Thanks for all the inputs and support Ava." - R Suraj Kumar "This was my first time taking an online data analysis class outside an academic setting. I worried about how the design would work for me as a working professional and if it would enable me grasp the material, but I must say that everything about the online course was smooth, convenient, and enjoyable. The concise tutorial videos, quizzes with solutions and availability of the instructor, made it easy for me to understand the topics. The method, order, and scheduling were accommodating and in my opinion, makes it convenient for anyone, anywhere to take the course, and of course, the content was very useful to me. I'm glad I took this course and I will strongly recommend it and others to follow, to anyone trying to develop more skills for data analysis. " - Clare Ofodile , Project Manager, Quality Assurance and Research Development Agency Nigeria (Lagos, Nigeria) "I like this course as it is very easy to understand and relevant for a beginner like me. I wish I could have some more courses like this one. I really enjoyed it and I started to like SQL more. A big thank you to my teacher!" - Ana Rotari This instructor is highly effective and efficient in getting the critical knowledge across. Unlike other courses, this one did not drag. Time was well managed with the instructor's teaching approach. In just three and a half hours, this course can be a career changing investment. – Jose Floresca Jr. "This course sparks my most interest in SQL and you MUST take to get strong foundation in SQL. Teacher Ava provides a very organized and informative course which is worth best 5 ***** (stars). And more than that, she always be there to support you to clarify your confusion. Believe me, after this course, your level of confidence improves a lot and exceed your expectation. For me, I'd like to attend more SQL courses from Ava in next levels. I hope she will have some good news." – Dannie Le
