Online Training Course- Oracle SQL for Data Science

Upon the requests of many people who listened to my presentations, I have built the online course Oracle SQL for Data Science. This course requires that students already have basic knowledge about SQL. The following is the description of the course.

Most of the core business data in an enterprise are stored in relational databases that support Structure Query Language (SQL). When data scientists perform common tasks such as data cleanse, validation, manipulation and feature variable calculation using SQL within database environment, they can achieve important advantages such as more compact code, easy deployment and security in comparison to moving the data outside of the database to a separate analytics environment. The instructor Dr. Jiang Zhou is one of the pioneers in developing SQL based in-database analytics solutions that are used by banks and insurance companies. In addition to his technical skills, he is, as one of his clients put it, "a great trainer, and a good presenter of theoretical data mining concepts so that they can be understood by most".
In this course, students will learn practical Oracle SQL skills to solve problems such as:

  • Data Validation
  • Data Summary
  • Detect and Remove Duplicates
  • Binning Variable Based on Equal Frequency
  • Build Good Variables for Predictive Models or Business Rules, e.g., RFM Analysis, Time Elapse Since Last Purchase, Number of Transactions in Last 3 Days, Moving Average Purchase Amount in Last 7 Days
  • Random Sampling
  • Gain Chart
  • Using View to Organize Process Flows
  • Histogram
There are totally about 4 hours and 30 minutes video presentations. SQL scripts that create data sets and perform the Data Science tasks are provided. Slides are included so that students can easily find the topics that they interested in.
