OBSOLESCENCE OF BUSINESS databases is accelerating, according to a report from Conduit Business Information. The annual study, covering the top 150,000 UK businesses, shows that database decay -’ the rate at which business databases become out of date -’ has leapt from 19% in 1997 to 24% in 1998. The findings provide a yearly yardstick of the rate at which staff change jobs or leave organisations: over 23% of marketers and 11% of managing directors moved on during 1997. In addition, 8% of company addresses changed during the year, the rate of change being higher among the top 10,000 companies. How-ever, a recession is likely to slow the rate of decay as people are less confident about moving jobs.
