This document introduces the MVC web framework CodeIgniter. It defines what a framework is and explains that frameworks provide a general application structure and handle common tasks, while libraries are used by code. The document then defines the MVC pattern, which separates business logic from presentation logic into the Model, View and Controller components. It provides examples of each component and how MVC is used for web applications. Finally, it proposes building a simple blog application using CodeIgniter to demonstrate MVC and the framework.

Editor's Notes
- #4: A set of code that…
- #6: เช่น Cookbook Bussiness Logic ก็จะเป็นการติดต่อ DB เอาตำราตาม Criteria มาโชว์ ส่วนจะโชว์ยังไงก็ Presentation Logic
- #7: ไม่ใช่การแยก Layer แต่เป็น 3 Module ที่แยกออกจากกัน
- #14: CodeIgniter มันก็คือ MVC Web Framework ตัวนึงนั่นแหละ แต่ทำไมวันนี้เราถึงเลือก CodeIgniter?
- #16: อ่อ! เดี๋ยวที่ Lab Theory จะมี Workshop Django ด้วยนะ วันที่ 26-30 ใครสนใจลงชื่อได้
- #18: แต่ในวันนี้ เราจะใช้ CodeIgniter เขียน Blog ง่ายๆ ของเราเองขึ้นมา
