Enterprise architect supports comprehensive functionality for modeling database structures. this paper covers the core features for data modeling over the full lifecycle of an application. initially, we discuss the basic modeling process – that is outlining a conceptual model and then working through the steps to form a concrete database schema. A database model makes use of a data model to express the design of a database using feature classes, relationships, and other constructs for a particular problem or set of problems.
