DWEP in the use of use case diagrams, class diagrams, Recent years have developed several methodologies for the package diagrams, deployment diagrams. Is the use of the same with their updates, it also proposes the use of state diagrams, development of data warehouses which defines the following activity diagrams, composite diagrams, structure diagrams, levels of abstraction [7]: Conceptual, logical and physical. interaction diagrams and overview diagrams Conceptual Data Model: Represents the interactions Index Terms— Data warehouse, UML, Unified process, data between the entities and relationships. This model is closer to models real world problems to solve. Highlights the following patterns in the data warehouse: Model Multidimensional / ER (Sapia) [8], model Star / ER (Tryfona) [9], GOLD model (Trujillo) [5, 10], model Husemann [11], YAM2 model [12]. I. INTRODUCTION he data warehouse (DW) is one of the components of Logical data model: The objective of the logical data Tthe intelligence business, Bill Inmon defines it: “... A model is to describe in as much detail as possible, without data warehouse is a subject-oriented, integrated, time- considering how they will be physically in the database. Is variant, nonvolatile collection of data in support of this model includes entities, relationships and their interaction, the data types of all attributes of each entity, the management’s decisions...” [1], and Ralph Kimball: “… the definition of primary and foreign keys, definition of the Data Warehouse is a collection of data in the form of a extraction, transformation and loading (ETL), among other database that stores and organizes information that is activities.
