Using InterBase Change Views

usingibchange

With Change Views, you have this patented method to work with that is a lot easier to develop and scale for your customer base. Using InterBase Change Views, you can now identify specifically what deltas have changed at the field level.

Change views are a subscription based model used to subscribe to some data and identify what data has changed in your InterBase database.  You create a subscription that covers different tables and columns and allow users the rights to subscribe to changes in the data.

During a connection, you can get an alert and then fetch your delta changes or use an TFDEventAlerter component in Delphi/C++Builder and even color code specific changes. For spanning a connection, you don’t have to be connected for it to record the changes. Once you start a database transaction you can have a subscription active then disconnect from your database and then start a new connection with a new transaction at a future point in time.

With Change Views, you :

  • Reduce costs and disk I/O by minimizing data syncs
  • Have little impact on performance
  • No external log tables
  • Scalability of users, even mobile ones
  • Track changes the way you want
