Database marketing is a form of direct marketing using databases of customers or potential customers to generate personalized communications in order to promote a product or service for marketing purposes. The method of communication can be any addressable medium, as in direct marketing. The distinction between direct and database marketing stems primarily from the attention paid to the analysis of data. Database marketing emphasizes the use of statistical techniques to develop models of customer behavior, which are then used to select customers for communications. As a consequence, database marketers also tend to be heavy users of data warehouses, because having a greater amount of data about customers increases the likelihood that a more accurate model can be built. There are two main types of marketing databases, 1) Consumer databases, and 2) business databases. Consumer databases are primarily geared towards companies that sell to consumers, often abbreviated as () (B2C) or BtoC. Business marketing databases are often much more advanced in the information that they can provide. This is mainly because business databases aren't restricted by the same privacy laws as consumer databases. The "database" is usually name, address, and transaction history details from internal sales or delivery systems, or a bought-in compiled "list" from another organization, which has captured that information from its customers. Typical sources of compiled lists are charity donation forms, application forms for any free product or contest, product warranty cards, subscription forms, and credit application forms. The communications generated by database marketing may be described as junk mail or spam, if it is unwanted by the addressee. Direct and database marketing organizations, on the other hand, argue that a targeted letter or e-mail to a customer, who wants to be contacted about offerings that may interest the customer, benefits both the customer and the marketer. Some countries and some organizations insist that individuals are able to prevent entry to or delete their name and address details from database marketing lists. == Background == Database marketing emerged in the 1980s as a new, improved form of direct marketing. During the period traditional "list broking" was under pressure to modernise, because it was offline and tape-based, and because lists tended to hold limited data.〔Stone, B (1997) Successful Direct Marketing Methods, NTC Business Books〕 At the same time, with new technologies enabling customer responses to be recorded, direct response marketing was in the ascendancy, with the aim of opening up a two-way communication, or dialogue, with customers. Robert D. "Bob" and Kate Kestnbaum were trailblazing pioneers of the new direct marketing, who were credited with developing new metrics including customer lifetime value, and applying financial modelling and econometrics to marketing strategies.〔Direct Newsline Nov 18, 2002〕 They founded Kestnbaum & Co, a consulting firm in 1967, and this was the training ground for many of database marketing's leading thinkers, including Robert Blattberg, Rick Courtheaux and Robert Shaw. Bob Kestnbaum was inducted into the DMA Hall of Fame in October 2002. Kestnbaum collaborated with Shaw in the 1980s on several landmark online marketing database developments - for BT (20 million customers), BA (10 million) and Barclays (13 million). Shaw incorporated new features into the Kestnbaum approach, including telephone and field sales channel automation, contact strategy optimisation, campaign management and co-ordination, marketing resource management, marketing accountability and marketing analytics. The designs of these systems have been widely copied subsequently and incorporated into CRM and MRM packages in the 1990s and later.〔Shaw, R. and Stone, M. Database Marketing. New York: John Wiley & Sons, 1988.〕 The earliest recorded definition of Database Marketing was in 1988 in the book of the same name (Shaw and Stone 1988 Database Marketing): :"Database Marketing is an interactive approach to marketing, which uses the individually addressable marketing media and channels (such as mail, telephone and the sales force): to extend help to a company's target audience; to stimulate their demand; and to stay close to them by recording and keeping an electronic database memory of the customer, prospect and all commercial contacts, to help improve all future contacts and to ensure more realistic of all marketing." 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Database marketing」の詳細全文を読む スポンサード リンク
