But if something goes wrong you might get an unexpected state in the database. Then you have to do more work in other places to deal with the fact that the database might be in a state that wasn't intended, but is theoretically possible because you didn't use transactions.<br/>=== Rex<br/>Rex: exactly the thing what i did in last year to boost up performance from 700 txn per second to more than 10K txn per second.<br/>Carfield Yim: handle rollback yourself you mean?<br/>Rex: <br/>u've to understand what is a system before talking the details...<br/>different application can apply different rollback.<br/>online/batch different are different.<br/><br/>Rule 1. make your txn simple.<br/>if it can't be simple, your design must have problem<br/><br/>u have to understand your capacity & limitation..... such article is meaningless if you have no actual requirement...<br/>if client is requiring 500 txn, that's no pt to have it like that.<br/><br/><script type="text/javascript"><!--google_ad_client = "pub-9426659565807829";google_ad_slot = "9359905831";google_ad_width = 728;google_ad_height = 15;//--></script><script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script>2007-03-30T11:22:20Z
