5、age of the data modeler as artisan is passing. Organizations can no longer afford the labor or time required for handcrafting data models from scratch. In response to these constraints, the age of the data modeler as engineer is dawning. Engineers build new products using proven components and mater
6、ials. In data modeling, the analogue to a component is a universal data model. A universal data model is a generic or template data model that can be used as a building block to jump-start development of the corporate data model, logical data model or data warehouse data model. Resistance to the use
7、 of universal data models is usually based on the belief that a particular organization has unique needs or the dreaded not invented here syndrome. This article describes the application of universal data models to several disparate organizations. It demonstrates that the same basic models, with min

The belief that a particular organization is unique because of its missions, goals, policies, values, functions, processes and rules can be very strong. After all, some businesses sell to people and othe

Each industry has its own set of business issues, and each organization within an industry varies as much as the differences between the personalities of various individuals.

10、izations A subject data area that is common to most enterprises involves the people and organizations that are part of conducting business. There is an important need to track the names, addresses, contact numbers and various relationships and interactions between the parties conducting business. En
11、terprises need to track information about customers, distributors, agents and suppliers as well as the internal organizations and people within the enterprise. This type of information is critical throughout all aspects of business including sales, marketing, customer service, purchasing, shipping,
12、invoicing, budgeting, accounting and human resources. Enterprises spend significant effort and time defining the most effective ways to model this type of information. The data model may lead to sub-optimal solutions if careful analysis is not conducted. For example, many data models depict separate
13、 entities for each type of party that exists in an enterprise. There may be entities word 格式. for CUSTOMER, SUPPLIER, INTERNAL ORGANIZATION, BROKER, EMPLOYEE, INVESTOR and any other role that a person or organization may play in the enterprise. There are problems with modeling the information this w
14、ay. What if a person or organization plays more than one role in the organization? For instance, what if an organization supplies products and/or services to our organization and also buys products from us? Does this mean that we maintain their name, addresses, contact numbers and other organization
15、al information in both the CUSTOMER and SUPPLIER entities? Under this scenario, if a name or address changes, the information needs to be changed in two places. Furthermore, does the organization play other roles such as an agent of the company or a distributor of products? Each time an organization
16、s role is modeled as a separate entity, there is a potential for redundant and inconsistent information. The same argument applies to people. Should we have a separate EMPLOYEE entity as well as a CONTRACTOR entity? What if a contractor becomes an employee of the enterprise or vice versa? The persons name, demographics and contact information may still be the same. The only thing that has changed is the nature of the relationship between the parties. It only makes sense to refer to pre-defined t
