ETL Patterns

TEXTETL vs ELT - these two methods are not in contradiction, rather they have different use cases.

ETL stands for Extract-Transfer-Load and is used when the transform better be performed on a fly. Indications are absence of environments, need to scale in transit, need to transform or mask in transit.

ELT is a pattern used when the real-time is not a requirement, processors and memory in transit are scarce, and there is plenty of additional hard drive. This is often a preferred migration method or data masking on the golden copy method.

Sometimes mixed techniques are used.
