The requirements. The business process.,信息,What data do we have and need to support
2、 the Business View? Information is also calculations and rules. Typically we see Logical & Physical data models here, all subject areas of the business. The data is worked on by the applications, used by the business. 应用 What functions and interrelations of functions do the applications have and nee
3、d? Sales, Marketing, Pricing, Manufacturing, Customer Management. Works against information to support the Business View. The applications work within the confines of the Information architecture, creating and consuming the data elements, rules and definitions of that architecture view.,技术 The bit I
4、T cares about most. The easiest to get WRONG because we dont concentrate on the other aspects of architecture FIRST! What do we have and need to support the other 3 Views without limitation? Choosing an ETL tool before you have defined an architecture is “SUB OPTIMAL” A separation of Business, Data,
