Informatica PowerCenter ETL steps

Informatica PowerCenter is included inside Hyperion Integration Management now. It has another name called DIM as a Hyperion component. The basics steps:
1. Create the 1st repository using Workflow Manager
2. Set up the Source connection and Target connection using Workflow Manager
3. Create the target tables using Designer->Tools->Warehouse Designer, select create table and drop table, don't need to add primary key
4. Use Designer->Tools->Transformation Developer to set up the transformation rules, such as : Max(), Min(), and some more complicated functions
4. Using Mapping Designer to set the mapping between the source tables and the target tables, and drag in the transformation objects. Save the repository
5. Use Workflow manager->Session->Task, to create a session that include the previous mapping
6. Create the work flow that include the session task
7. Everytime if you change the mapping and the transformation,you need to refresh the session and workflow, there is no refresh button, but you need to edit the connections and save the repository and validate. This is important even if you make a slightly change in the mapping.
8. Run the workflow and see it in the workflow onitor.
