DataQualityTools is a collection of tools to help businesses improve the quality of their databases. The central components are a series of functions which help to find duplicate records and, above all, a function for error-tolerant doublet search based on postal addresses. This allows you, in the case of direct marketing, to avoid double solicitations and the redundant maintenance of customer addresses and other records. Of course, this saves significantly on your expenses. But it also improves the outward image of your company. And through the consideration of advertising black lists, you can also avoid trouble with advertising recipients who do not wish to receive advertising.
