The solution we developed uses a database (sqlserver 2005) for persistence purposes, and thus, all updated data is saved to the database, instead of sent to the program.

I have a front-end (desktop) that currently keeps polling the database for updates that may happen anytime on some critical data, and I am not really a fan of database polling and wasted CPU cycles with work that is being redone uselessly.

Our manager doesn’t seem to mind us polling the database. The amount of data is small (less than 100 records) and the interval is high (1 min), but I am a coder. I do. Is there a better way to accomplish a task of keeping the data on memory as synced as possible with the data on the database? The system is developed using C# 3.5.

  1. Since you’re on SQL2005, you can use a SqlDependency to be notified of changes. Note that you can use it pretty effortlessly with System.Web.Caching.Cache, which, despite it’s namespace runs just fine in a WinForms app.
