A dimensional model is used in the building of a data warehouse, but what exactly does it do?
Step by step
Solved in 2 steps
- The ______________ model is a simple but highly useful way to organize data into collections of two-dimensional tables called relations.Using a graphics program, develop an entity-relationship diagram for a database application for an Internet bookstore where students buy textbooks from a salesperson and receive invoices for their purchases. Use Figure 5.5 as a guide.A new sales ordering system needs a relational database that contains a customer table, a product inventory table, and an order table. Use a word-processing, graphics, or spread-sheet program to draw an entity-relationship diagram showing the relationships among these entities. Next, design each of these tables showing the keys and attributes to be included in each table. Include five sample records for each table.
- In the hierarchy of data, what is the difference between a data attribute and a data item? What is the domain of an attribute?When creating a data warehouse, a dimensional model is employed, but what precisely does it do?Is it really necessary to have a dimensional model when it comes to the construction of data warehouses?
