Modern database and applications development software is so easy to use that many people can quickly learn to implement a simple database and develop simple applications within a week or so, without giving design much thought. As data volume grows and when users request addition functionality, they might incorrectly add columns in table since appropriate database design is not available. This not only causes data redundancy in database but also can cause performance issue to application and database as well. Ultimately, due to poor database design, the business would be the loser.
A good database design not only avoids data redundancy but also improves database performance over period of time as the database volume grows and when business changes are requested , it would be far more easier to understand as where to make the appropriate changes in the Database. The data modelling and database design is like a building blue print and ultimately it would make application users happy and business would benefit.
This course uses the Oracle SQL Data modeler extensively to discuss and demonstrate Database modelling and Database design.
Oracle SQL Data modeler is a tool, which make learning Data modelling and Database design much easier and also provides you with a professional approach design database for business application effectively to plan, develop, implement and maintain them on an ongoing process.
In this course you would learn:
Develop a Data Flow Diagram by identifying processes, external agents, information stores and information flows that show how the information flows Business flow Diagram
Create an Entity Relationship Diagram by identifying entities, attributes, relationships.
Normalize the Entity Relationship Diagram to third Normal form
Validate Logical and Relational Model through Design rules
Engineer the Entity Relationship Model into an relational database design
Complete the Physical Model and generate the DDL scripts
Finally, at the end of the course, you would understand the importance of data modelling and database design.

So far it is Average/Good. Since I am experienced person, I feel it is slow. Looking forward for next chapters
It was a good refresher on many things I already knew and I got some of the detail I needed on aspects of the data modeler that were unfamiliar to me. Perhaps there is an advanced version that drills deeper into the tool, down to the field level, and the various components within in?
The presentations contains heavy slides in general, and the text and font on the practice tool is too tiny to watch.
I was looking for a course that will take me through factors to be considered in designing a data base and also the hands on of processes involved. This course meets my demand beyond my expectation. Examples of each concept is so simple for a beginner to understand and build upon The instructor's pace is perfect. He explains every concept before moving into the DEMO. This course is the bomb for anyone who has basic familiarity with RDBMS and looking into getting a career as a data modeller or Database developer. Highly recommended!!!
