What is and Why Data Modeling?

What is Data Modeling?

Act of exploring data-oriented structures and their relationship
Something similar to class modeling in OO design

Why Data Modeling?

Abstraction
- A well abstracted data model will be economical and flexible to maintain and enhance since it will utilize symbols to represent a large body of design.
Transparency
- A good data model enables its designer to perceive truthfulness of design by presenting an understandable picture of inherently complex ideas.
Effectiveness
- An effective data model does the job accurately, reliably, and economically

I have attended the 5-day Java Programming code camp and it has been very helpful. The course content is very detailed including lot of examples and homework for each topic. Sang is very knowledgeable, also very patient in making sure everyone understands the content covered. He goes well and beyond the expectations. After taking the course, I feel confident now to take the Oracle Java Programmer certification exam. I am looking forward for 'Advanced Java Programming' code camp in future. I would definitely recommend jpassion to anyone.

I am participated in the Java Programming - Learn Java for the first time (beginners) Code Camp and I have to mention that it is very well organized, contains very interesting exercises and home-works, and the way in which Mr. Sang explains everything is very great and effective specially by having the possibility to ask any question do you want. I am very eager to attend another Code Camps and also to read and learn from all these great materials. I am suggesting this website for everyone, beginners can consider it as an effective station to start from, and the experienced people can use it to review and refresh their knowledge..

Java Live code camp was really an amazing experience. Instructor is there to answer you questions, it is something not to be missed at any cost, especially the way it has gone through is marvelous.

If you want to understand Java thoroughly, take this course. Clear explanations and lots of meaningful examples.

This is the best resource for learning Java programming. The material is thorough and well-detailed, yet concise. The Web Services and SOA Programming bootcamp was a huge springboard in my career as a middleware developer and in my personal persuits in Java development.

I had attended the 4 day training program on Java. The course agenda was clear and the presentations were easy to understand even for a novice in programming. Concepts were clearly explained with adequate hands on exercises. Above all as the name suggests "jpassion",Sang Shin teaches with so much passion, even if we could imbibe a quarter of it, we would be good programmers. Looking forward for many more.

JPassion code camps - Fastest, easiest way to build real Java development skills. Perfect for those short on time, money to get what you need at the pace you need. Missing class is not an issue since all material including lectures is available for download. If you submit the homework exercises, you get a course certificate.

I enjoy the books by Cay Horstmann such as core Java (volume 1 and 2) and Big Java.. I also like the Udemy classes on Java and Coursera and edX.. However, jPassion gives the direct live interaction with Professor Sang Shin that these other formats of learning don't do. In those other formats you can post a question but they may or may not answer it, and you have to wait for the answer. In jPassion Sang is very open to answering all types of questions even unrelated to the exact topic being discussed!! His material is quite in depth even when it's called Introduction or Beginner etc. It's also a great motivating factor to hear him live and try to wake up early and listen live. Thanks for these great teachings Sang..

This course was incredible value – and very well done. I find that I need a starter class to begin a new language and the ability to learn from - and interact with – a live Instructor is marvelous.

Martin B.

Great codecamp! It helped to understand some of the complex Java programming concepts in depth by interacting instructor that breaks down the complexity and makes it easier to understand.

Natalya P.

Very good course. Sang shin (the instructor) makes it very hands on and at the same time is willing to answer all the conceptual questions thus making it overall a very interactive and practical experience
