Database planning, beyond that of a personal or small business end user database created by a database management package, typically requires use of a top-down data planning process based upon the systems development model covered earlier:
1. Data Planning. At this stage, planners develop a model of business processes. This results in an enterprise model of business processes with documentation.
2. Requirements Specification. This stage defines the information needs of end users in a business process. Description of needs may be provided in natural language or using the tools of a particular design methodology.
3. Conceptual Design. This stage expresses all information requirements in the form of a high-level model.
4. Logical Design. This stage translates the conceptual model into the data model of a DBMS.
5. Physical Design. This stage determines the data storage structures and access methods.
