strategic data planning and management steps:

Enterprise Modeling Physical DB Design Application Programs Entities Data Model Logical Subject Area Databases User Views A strategic data planning process begins with the development of an enterprise or business model (Box 1, above). The enterprise model depicts the functional areas of the firm, and the processes that are necessary to run the business. The next step is to identify corporate data entities and to link them to processes or activ- ities (Box 2). Data requirements are thus mapped onto the enterprise model, leading to the identification of subject areas for which databases need to be implemented (Box 3). In general only selected portions of the enterprise model and subject area databases are chosen for bottom- up design. Building the logical data model is the first step. The data model (Box 5), results from a synthesis of detailed management and end-user data views (Box 4) with the results of the previous top-down entity analysis (Box 2). Database design and subsequent design of application programs (Boxes 6 and 7) proceed from the logical data model.
