Tackling the Gaps and Islands Problem with T-SQL Window Functions

The gaps and islands problem is a common problem in data analysis. Some examples are:

• How long are active periods that my server was running? Or, how long are the periods that the server was down?
• On average, how long are the billable periods of my consultants?
• What was the longest stretch of days without rain?

In this session, you'll be introduced to the powerful concepts of window functions in T-SQL. With a practical use case, the gaps and islands problem is explained and solved. At the end of the session, you should feel confident in using window functions in your own data analyses.

A basic understanding of T-SQL querying concepts is required to follow this session.
