jonniesweb / code.java
Last active June 11, 2017 20:09
Example optimization of implementing existing Java business logic into SQL update statements. The example is of code that moves an 'item' to the correct next 'step' based on if the item is associated to a 'click' of a 'link'.
Step process(Item item, LinkStep step, DataAccess access) {
boolean result = false;
if (step.getLink() == null) {
// item associated with any link being clicked
result = access.userClickedOnAnyLink();
} else {
// item associated with a specific link being clicked
