Lesson 10: Three Level Database Architecture
Sometimes it is possible, and efficient to not store specific data if the information can be easily derived from stored data. For example, the GPA of a student can be displayed when the student searches for his or her GPA but it is not stored only calculated when needed.

E-learning 5This is the first time I have attended a class in this format and wondered how effective it would be. It was very effective and therefore I would definitely introduce all my friends and family to attend classes in the same format. The instructor was very knowledgeable and provided a wealth of information about the current version, especially since the last version I used was several releases ago.

Information Technology 5I have twenty plus years of experience taking training courses. I am not easily impressed, reserved with my praise, and do not usually complete surveys. My instructor is excellent, the best I've experienced on a software subject, and I couldn't imagine him doing a better job of seamlessly walking students through a breadth of information in a remote environment. He did a fabulous job packing everything and addressing student questions. I am very impressed.
E-learning 5We just wanted to let you know that the service provided, from registration to training is a very positive experience for everyone. We intend on taking more classes in the future and referring any new hires as well as friends/family members to take courses at World Class Education
