Hi guys, in this lesson, we will create our model classes database change sets with liqui base. To do it, we will create a new XML file under the change lock. Our new XML file name will be DD changelog 1.0. xml this file will be in wiki base XML format This file will contain database change log property. So we should create the XML database change log element. In liqui base database change element is constructed from change sets. Each chain set has altered and unique ID attributes.

First of all we will write SQL to create cross table Then we will create rollback for stable Secondly, we will write eska to create transaction table Then we will create a rollback for transaction table. Okay, that's all about the key base implementation for other classes. In next lesson, we will create test data for these tables. Thank you
