Please create a Entity Relationship Diagram (ERD) and a Data Flow Diagram (DFD) that models the DMI system using the following scenario:

1. Sell the DMI system to every online market sector that can benefit from data mining technology:

a.Small and large business. b.Local and worldwide. c.Specialized product line (e.g., Cyberia) or diversified product line (e.g., amazon.com).

2. Have the system track customers shopping and purchasing habits by collecting and storing data concerning registered customers to include:

a.Website visits. b.Web page browsing (which pages, frequency, etc.) c.Ordered products.d.Frequency, quantity, season, etc.

3. The system would apply data mining techniques to the customer information database each e-business corporation and:

a.Produce lists of customers with specific recommendations for products to be marketed to them. b.Automatically send marketing materials on recommended products to target customers. c.Generate reports with raw data, summary data, statistics, etc.

4. The DMI system (DMIS) would be provided to each client at a reduced purchasing and maintenance fee. However, the client must agree to have their customer information database (i.e., market research data that was collected by the clients DMIS) shared with DMI. The idea is that, by DMI having access to the (distributed) customer databases of all of its clients or other potential clients.
