Data modeling and Relational database design

Unlock the Power of Database Design for Application Development

Modern database and application development tools empower rapid development, but neglecting database design can lead to significant problems. While you might be able to quickly implement a simple database and application in a week, a lack of thoughtful design can result in data redundancy and performance bottlenecks as your data grows and requirements evolve. Poor database design ultimately impacts your business.

Effective data modeling and database design are crucial. Think of it as the blueprint for your application – a well-designed database avoids redundancy, improves performance, and simplifies future modifications. A solid foundation ensures application users are satisfied and your business thrives.

This course leverages Oracle SQL Data Modeler to provide a practical, hands-on approach to database modeling and database design. Oracle SQL Data Modeler simplifies the learning process and equips you with the skills to professionally design databases for business applications, covering planning, development, implementation, and ongoing maintenance.

In this course, you will:

• Process Modeling: Learn to develop a Data Flow Diagram, identifying processes, external agents, information stores, and information flows to visualize data movement.
• Business Flow Diagram: Create a Business Flow Diagram to map out key business processes.
• Logical Model: Develop an Entity Relationship Diagram (ERD) by identifying entities, attributes, and relationships. Learn to normalize the ERD to Third Normal Form (3NF).
• Relational Model: Validate your logical and relational models using design rules.
• Relational Database Design: Engineer your Entity Relationship Model into a relational database design.
• Physical Model: Complete the physical model and generate Data Definition Language (DDL) scripts.

By the end of this course, you'll deeply understand the vital importance of data modeling and database design for successful application development.

Happy Learning!
