The intense interaction between marketing and data mining is common todays businesses. A new approach created called; database marketing. Business managers began to use this approach more widely especially in terms of customer segmentation and Customer Relationship Management (CRM). In this work, we developed a data mining application-which is rapidly growing and becoming limelight- for direct marketing. As a sub-branch of direct marketing, telemarketing is used often by banks. But today, customers do not enjoy this and commonly they prefer not to answer calls. To prevent from this decline in the popularity of telemarketing, data mining is an important tool. Banks can understand customers and their behaviors more deeply using such application. As a result, they are able to develop a stronger relationship with them. In this work, We tried to produce some beneficial information about bank customers via the results of association rules. In that context, We analyzed the dataset of a Portuguese bank using CRISP-DM (Cross Industry Standard Process for Data Mining) methodology. It offers a case data mining study for banks or other businesses which employ telemarketing for know their costumers better and convey their proposals to specific costumers in most appropriate way
