This Assignment Consists Of Two Sections: A Design Do 553686

This assignment consists of two (2) sections: a design document and a revised project plan

This assignment consists of two (2) sections: a design document and a revised project plan. You must submit both sections as separate files for the completion of this assignment. Label each file name according to the section of the assignment it is written for. Additionally, you may create and/or assume all necessary assumptions needed for the completion of this assignment.

One of the main functions of any business is to transform data into information. The use of relational databases and data warehousing has gained recognition as a standard for organizations. A quality database design makes the flow of data seamless. The database schema is the foundation of the relational database. The schema defines the tables, fields, relationships, views, indexes, and other elements. The schema should be created by envisioning the business, processes, and workflow of the company.

Since your company is an innovative Internet-based company, movement toward data warehousing seems to be one of the most viable options to give your company a competitive advantage; however, these concepts must be explained to the executive board in a manner to garner support.

Section 1: Design Document

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. The schema should include the tables, fields, relationships, views, and indexes.
• Identify and create database tables with appropriate field-naming conventions. Determine 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. 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 graphical tools. Explain your rationale behind the design of your DFD. Illustrate the flow of data including inputs and outputs for the use of a data warehouse, mapping data between source systems, operational systems, data warehouses, and data marts.

Your diagrams and visuals should be included in the appendix of the design document. All references to these diagrams must be cited within the text.

Formatting requirements: Typed, double spaced, Times New Roman font size 12, with one-inch margins. Include a cover page with title, student name, professor's name, course title, and date. The cover page and references are not included in the page count. Use APA formatting for citations and references.

Section 2: Revised Project Plan

Use Microsoft Project to update the project plan—specifically the summary and detailed templates—from your previous project deliverable: Business Requirements. Add three to five (3-5) new project tasks, each with five to ten (5-10) subtasks.

The overall goal of this assignment is to understand and communicate the methods for implementing process change in IT organizations and leveraging technology to improve organizational processes. This includes researching relevant issues, applying best practices, and demonstrating strategic insights through clear and concise writing.

Paper For Above instruction

In today’s digital economy, data management is a critical driver of competitive advantage for internet-based companies. Proper database design and data warehousing are essential components for transforming raw data into meaningful business insights. This paper discusses the importance of relational databases and data warehousing, proposes a detailed schema for an innovative online company, and presents the associated diagrammatic models that support such a system.

Relational databases underpin the organization’s ability to store, retrieve, and manage vast amounts of structured data efficiently. They facilitate data integrity, reduce redundancy, and enable complex querying capabilities. Data warehousing, on the other hand, allows for consolidating data from multiple sources, thereby supporting advanced analytics, reporting, and decision-making at an executive level. These systems ultimately enhance managerial oversight by providing timely and accurate insights into organizational performance.

The proposed database schema is centered on supporting core business functions, such as customer management, product cataloging, sales transactions, and marketing campaigns. For example, tables such as Customers, Products, Orders, and Employees will form the backbone of the system. Each table is designed with appropriate naming conventions to promote clarity and consistency. Primary keys uniquely identify each record, while foreign keys establish relationships between tables, ensuring referential integrity is maintained throughout the database. This approach minimizes data anomalies and supports efficient data retrieval.

Normalization to the third normal form (3NF) ensures that each table contains atomic values, eliminates redundant data, and reduces dependency issues. For instance, the Customers table will have a primary key CustomerID, with related order details stored in an Orders table linked via the CustomerID foreign key. Similarly, products and categories will be stored in related tables, reflecting a normalized and scalable structure.

The Entity-Relationship (ER) Diagram visually depicts the relationships and constraints among various entities within the database. For example, the relationship between Customers and Orders is one-to-many, signifying that one customer can place multiple orders. The design rationale emphasizes ease of data retrieval, consistency, and scalability, facilitating future growth and integration needs.

The Data Flow Diagram (DFD) illustrates how data moves within the system—from source systems like online transactions and customer interaction logs to operational databases, data warehouses, and finally, data marts used for specific analytical tasks. This diagram emphasizes the input-output flow, showcasing the seamless integration of operational processes with analytical tools. It highlights how data from diverse sources is cleaned, transformed, and loaded into the warehouse, supporting strategic decision-making.

In introducing data warehousing concepts to the executive board, it is essential to emphasize how these systems enable rapid access to comprehensive data insights, improve decision-making speed, and foster a data-driven culture. The schema and diagrammatic models serve as foundational tools that support these goals, ensuring data consistency, integrity, and accessibility.
