Most business applications have to deal with data manipulation. Users are able to see, change, delete, and add data. All these actions are executed according to and in the context of a set of rules dictated by the business. In its more fundamental form, business applications include graphical user interfaces to perform CRUD actions over the data. CRUD is an acronym for Create, Read, Update, and Delete. This chapter explores the design and implementation of CRUD views.

We'll start with a quick discussion about CRUD views from a User Experience (UX) perspective. Then, we will move on to how to design and implement CRUD user interfaces using two different UI designs. This chapter also explains the basics of data binding, shows how to use the Java Bean Validation API, and demonstrates how to render UI components inside Grid components.

This chapter covers the following topics:

• CRUD user interface design
• Data binding
• Validating with JSR-303
• Grid renderers
• Filtering
