Our whole design approach with our web applications is based on reducing round-trips and minimising the size of data being sent back and forth. We have come up with a number methods to achieve this. First and foremost we return all data from SQL Server in XML. Like the article suggests this allows us to build up mutiple 'select' statements within a single SP and return a single block of data. This means we can populate a form with one SP which includes all the data such as lookup info for combos, the parent record and related child recordsets if appropriate. Where we have to return complete recordsets - again we do this in the ADO XML format - we strip out the updates, deleted etc on the client app before posting them back to the server. If a user changes data then that changed data exists on the client - therefore in many cases there is no need to send it back to the server and then refresh the whole record - simply send back your changes and return only what you must - which may be nothing! We have found that this approach makes a huge difference to performance and even helps compartmentalise the structure of the database along with reducing the number of unnecessary SPs, not to mention the reduced impact on bandwidth and performance gain.
