Hi,
I have product data in my source system which i need to load in target.
We need two jobs.
1) full load on weekend.
2) only delta data on weekdays.
on Sunday, we will truncate the staging table. we will load full data from source in staging table. and from staging we will produce a target fla file.
on weekdays, we will identify the changed rows in source. source table has UPDATED_ON column. we just need to compare that column value with sysdate and extract delta for today. we need to update only these rows in staging db. Then extract only these updated rows in target flat file.
What will be the best transforms to use in above two cases.
