ETL Phases

Oracle BI Applications ETL processes includes three main phases: SDE, SIL, and PLP.

• SDE stands for Source Dependent Extract. In this phase, SDE tasks extract data from the source system and SDS and stage it in staging tables. SDE tasks are source specific.

• SIL stands for Source Independent Load. Load tasks transform and port the data from staging tables to base fact or dimension tables. SIL tasks are source independent.
• PLP stands Post Load Process. PLP tasks are only executed after the dimension and fact tables are populated. A typical usage of a PLP task is to transform data from a base fact table and load it into an aggregate table. PLP tasks are source independent.
