#3 Databases, ORMs ... and why you don't need gii - Yii2 Tutorial

Lecture #3/12 -An overview on how Yii2 manipulates databases. We introduce the all important Object Relational Mapping (ORM) concept, and how this is implemented in Yii2 by the ActiveRecord class. We tried out gii (the code generation tool of Yii2) to produce a grid of records with CRUD capabilities (Create-Read-Update-Delete). We introduce the all important Gridview widget. However we remain skeptical whether the benefits of using gii outweigh the lurking pitfalls.

In the lecture I wrongly refer to ORM as Object Relational Model. The correct term is Object Relational Mapping. It is a technique implemented through the ActiveRecord class (Model) of Yii2.
