Define relationships in Visio usingprimaryandforeignkeys so that you can create a collection of data from more than one table. Note:The Database Model diagram is only available in certain versions of Visio. See
The next section explains these databases, each with its ER diagram and an explanation of the motivation for its design. You’ll find that understanding the ER diagrams and the explanations of the database designs is sufficient to work with the material in this chapter. We’ll show you how ...
The number of customer relationship management (CRM) implementations has grown dramatically in recent years. Data Mining is the process that uses a variety of data analysis and modeling techniques to discover patterns and relationships in data that may be used to make accurate predictions...

Transitioning from a Class Diagram to an Entity-Relationship Diagram is a crucial step in the data modeling process for IT systems. While Class Diagrams provide an excellent high-level view of the system’s architecture, ERDs offer the detailed representation need...
2. Data mining: an overview 2.1. Definition “Data mining” is defined as a sophisticated data search capability that uses statistical algorithms to discover patterns and correlations in data [2]. The term is an analogy to gold or coal mining; data mining finds and extracts knowledge (“data...
