New to ETL
hi guys
I am working in an environment where i am new. The following is the scenario we have
We have two projects: Peoplesoft project and java project( java UI with backend oracle)
We have data coming from PeopleSoft project to java project (in oracle database).
Data is exported from oracle (using Java UI) to Peoplesoft.
The above process is done using ETL and Autosys.
Any idea what ETL and Autosys is and how the above tasks are performed using ETL and autosys?
thanks

There is no 'set' tools for etl. It is a concept.
Anything that will allow you to extraxt data, massage it if neccessary, and load it is 'etl.
I believe sql developer has a way to extract data to a CSV file or at the least I think the sqlworksheet will allow the sqlplus spool command.
That works as the 'E' in etl.

Extract:
create table staging_tab as
select * from test_table;
Transform:
update staging_tab set col1 = col1*2;
Load:
insert into final_table (select * from staging_tab);
I know that it's simple and it might not give you the good feeling about ETL, but without specific question it's difficult to help you.
Moreover typically Extract happens on the other systems that the Transform and Load. You typically extract data from online systems, them move them to data warehouse and there you transform and load.

Not sure what 'autosys' reference you are using but try this one:
http://en.wikipedia.org/wiki/CA_Workload_Automation_AE
Your team lead should be able to tell you what it is.
