Having run a heavily modified version of PowerDev’s Circle membership database for five years, users at the Athenaeum Club started to report performance issues culminating in several incidents of database corruption. Whilst these were quickly fixed, they were indicative that the system was reaching Microsoft Access’ limits. The club therefore accepted PowerDev’s proposal to upgrade the system by replacing the server database that was running in Access 2003 with SQL Server 2008 R2 and upgrading the Circle client from Access 2003 to Access 2013. This was co-ordinated with an upgrade of the server, network and PCs at the club. Users at the Athenaeum are currently testing the upgraded system but are already delighted with the speed improvement.
