-Visual Explain is.....
+Visual Explain is an essential tool for anyone who wants to use SQL Query Engine (SQE) insight to understand the performance characteristics of their SQL.
+Visual Explain is often referred to as VE. SQE, as a cost-based optimizer, considers many factors before settling on the "plan" for query implementation. 
+By using VE during development and unit tests, IBM i application developers can gain crucial performance insights, and tune their SQL prior to promotion.

 For this section, we are using the sample database. If you're doing this workshop as part of a lab, the sample data will be created for you automatically. You can use `qsys.create_sql_sample` to create the same sample data if you are using your own system.

 Notebooks are documents that contain a mix of rich Markdown, executable code snippets, and accompanying rich output. These are all separated into distinct cells and can be interleaved in any order. They are great storytelling devices, allowing you to interleave Markdown elements like images, math equations, and explanatory text with your code. Notebooks can be a perfect way to share and explain your ideas with coworkers or the public community.
