CIS 590 Week 6 Project Deliverable 3 Database and Data Warehousing De CIS 590 Week 6 Project Deliverable 3 Database and | 页面 2

Write a six to ten (6-10) page design document in which you:
Support the need for the use of relational databases and data warehousing. From a
management standpoint, it may be important to show the efficiencies that can be gained for
executive oversight.
Create a database schema that supports the company’s business and processes. Explain and
support the database schema with relevant arguments that support the rationale for the
structure. Note: The minimum requirement for the schema should entail the tables, fields,
relationships, views, and indexes.
Identify and create database tables with appropriate field-naming conventions. Then, identify
primary keys and foreign keys, and explain how referential integrity will be achieved. Normalize
the database tables to third normal form (3NF).
Identify and create an Entity-Relationship (E-R) Diagram relating the tables of the database
schema through the use of graphical tools in Microsoft Visio or an open source alternative such
as Dia. Note: The graphically depicted solution is not included in the required page length but
must be included in the design document appendix. Explain your rationale behind the design of
the E-R Diagram.
Identify and create a Data Flow Diagram (DFD) relating the tables of your database schema
through the use of graphical tools in Microsoft Visio or an open source alternative such as Dia.
Note: The graphically depicted solution is not included in the required page length but must be
included in the design document appendix. Explain the rationale behind the design of your DFD.
Illustrate the flow of data including both inputs and outputs for the use of a data warehouse.
The diagram should map data between source systems, operational systems, data warehouses
and specified data marts. Note: The graphically depicted solution is not included in the required
page length.
Your assignment must follow these formatting requirements:
Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all
sides; citations and references must follow APA or school-specific format. Check with your
professor for any additional instructions.
