We'll cover what the use cases are for DSL, motivations for making it, key characteristics, how to use it and some concepts used to create it. DSL queries can be used instead of hand coded finders to write Java code that looks like SQL. Since they are objects, parsing and rewriting DSL queries is much safer than query strings. DSL queries prevent vendor specific syntax, enforce type safety, reduce syntax errors, and improve code readability.

Audience is any programmer that knows some Java and SQL.
