Heavy processing in Oracle database?

Hi All,

I am working in an application where I need to be able to process at worst... 620,000+ records. I need to compare data between 2 tables, the first table has 620k records which i need to manipulate and roll upto 20,000 records, these then need to be compared against another 20,000 records in table2.

Our application uses Spring framework and Oracle 10g. It is a web application used internally, when the user clicks a button this processing and comparing needs to happen on the fly and return data to the user. It is not a batch job overnight or anything. I am wondering is this feasible given that it needs to happen on the fly? Also what approach is best, can we use cursors for this? I am not too familiar with using cursors in oracle...are they used just for batch jobs? What about stored procedures?

Any help will be much appreciated from you db experts out there.

Many thanks!
I agree. Here's the link:
