DMLRecipes
Demonstrates various ways of making Data Manipulation Language (DML) calls. Note that this class demonstrates both Database.* methods as well as DML Keywords. Note: There is a @suppressWarnings annotation on this class for Cyclomatic Complexity. You can read more about what Cyclomatic Complexity is here: https: Cyclomatic Compelexity score are harder to test, and more prone to bugs because of the sheer number of branching logic paths available. This class is made up of a number of small methods, each of whom does CRUD/FLS Checks and therefor every method includes at least one branching path - but not much else. Because this class is designed to teach safe DML I've decided to mute this warning. Other classes in this repository do not have such a high Cyclomatic Complexity because the ratio of logic to if/else statments is much lower.
