Master Data Management Vendors
Data analysis is not new. Even before computers are used, information gained in business travel or other activities is reviewed in order to make the process more efficient and more profitable. Of course this is a relatively small scale business given the limitations imposed by resources and labor; The analysis should be manual and sluggish by modern standards, but still useful. Voting, for example, has been done since the beginning of the 19th century, almost 200 years ago. The first national survey took place in 1916 and involved the publication of Literary Digest which sent millions of postcards and counted the yields. As a result, they correctly predicted Woodrow Wilson's election as president.
Since then, the volume of data has grown exponentially. The advent of internet and faster computing means that vast amounts of information can now be harvested and used to optimize business processes. The problem is that conventional methods are not at all suitable for deciphering all numbers and understanding it. The amount of information is phenomenal, and in that information there are insights that can be very useful. Once patterns are identified, they can be used to customize business practices, create targeted campaigns and remove ineffective ones. However, as with large amounts of storage, special software is required to understand all of this data in a useful way.
