Data Collection Automation

I need a macro/script which will search a database and download the data that is provided for each search.? I have a file of company codes and need to automate the data collection process since the search needs to be performed separately for each case.? The database does internally update though (instead of taking you to a new page in each step) so you would need to access the pages (layers)? separately. The automation would be very standard though, with? very little? heterogeneity in? the search/automation process.? It would need to be in? either a program that I have or can easily get.? (so for instance java,? imacro would be fine) Thanks!
