Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

  3. Retrieve objects from data store
  4. Update object and persist changes back to data store using ORM framework
  5. Delete data in data store
  6. Detach data and reattach data
  7. Implement eager loading of related domain
  8. Implement lazy loading of related domain objects
