1 Explain the Top-Down and Bottom-up Data Warehouse development Methodologies.

Answer: Despite the fact that Data Warehouses can be designed in a number of different ways, they all share a number of important characteristics. Most Data Warehouses are Subject Oriented. This means that the

2 Differentiate E-R modeling and Dimensional Modeling

Answer: E - R Modeling

Entity - Relationship modeling is a very popular method for designing databases. E-R modeling, as it is often called, may be described as a topdown approach, in that it encourages looking at the “big picture" first. We begin by describing the world in terms of entity types that are related to one another in various
