The purchase of this book will entitle you to download the sample program during 6 months, for didactic use only. You must make your own program, with the knowledge learned.
Imagine that your boss tells you that you have to make a screen very similar to another one. There are two options: the first one start from scratch, the second one is to copy the code from the first screen to the second one, changing only what affects to the data (Components) and without touching what is fixed (Behavior).
By reading this book you will learn how to make a program that starting from templates (the fixed part of a program, that is to say the behavior), substitutes, in the templates, the changing parts of the program, that is, the data. These changing parts, (the data), of a program will be taken from the Database Metadata. For each tabla of the Database, if you joing the fixed parts of the templates and the changing parts, the result will be a web page that will allow you to give additions, deletions and to do modifications in each table of the Database.
