Industrial control systems cannot—unlike humans—see, hear, and monitor processes by themselves. Instead, they use industrial sensors to convert mechanical, magnetic, thermal, optical, and chemical variations into electric voltages and currents. In this course, Zahraa Khalil covers the most common types of industrial sensors used within the field of industrial automation. She looks at proximity, temperature, pressure, and level sensors, and explores the operating principles and common applications of each. If you’ve got the basics of programmable logic controllers (PLCs) programming down and want to see what you can do with industrial sensors, join Zahraa in this course.

Learn how to set up and work with PostgreSQL, one of the world’s most popular open-source database platforms. Learn how to build a database, retrieve data with queries, and more.

In this course, database expert Adam Wilbert introduces you to a number of advanced query techniques that you can use to better understand your data. Statistical analyses involve understanding the shape and size of the full data set, and deeper insights can be gained by grouping data together to obtain some very useful metrics. Adam shows you how to create basic groups and apply aggregate calculations, then moves into window functions that create subgroups for more granular analysis. He goes over statistics that are based on sorted data within groups, such as the median value, the first and third quartiles of a dataset, the most frequent value, and more. Adam also covers ranking, hypothetical sets, percentile functions, and conditional expressions for further manipulating query result sets. He concludes with some additional querying techniques that you may find useful in solving common problems.

PostgreSQL is one of the most popular open-source database management systems.
