You should never stop learning, especially within the IT industry. There are many fields to move into nowadays within the data space, you still have your classic / cloud DBA roles (crossing over to roles such as data engineer) and development roles too. Looking at the industry I see things like Big Data and Data Science becoming more popular. This led me to the Microsoft Professional Program where I spent my time completing the Big Data track – unfortunately it will be retired by Microsoft.
I wanted to find something else, more generic with theory-based background as well as learning the software practical skills in my own time. I researched and found 365datascience.com A well-structured course made up of both videos and lecture notes to get to grips with data science.
All the topics covered are those that you would expect – spreadsheets (excel) , probability, statistics, SQL, python and R. I am not saying you will become an expert over night, but you will become more confident with the different topics.
