+# PRA06
+
+## Remarks
+
+- Created LayoutRender for Book and Speaker
+- Binder working with SelectBox. Definition of equals and hashCode of Book and Speaker
+- Used ComponentRender in SelectBox for Book and Speaker
+- Used ComponentRender in Grid for Book and Speaker
+
+
+## Tasks
+
+1. [x] Enhance Data Model
+
+    - Create `Conference` and `Speaker` entities
+    - Implement OneToMany and ManyToOne relationships
+    - Use `Conference` as a join table
+
+1. [x] Configure Data Loading
+
+    - Create `data.sql` file for initial data load
+    - Configure `application.properties` to load data only on first start
+    - Remember to use SQL data loading: `spring.sql.init.mode=always` in `application.properties` just the first time, then `never`.
+
+1. [x] Create Vaadin Views
+
+    - Implement `MainLayout`
+    - Create one view per entity (`Conference`, `Speaker`)
+    - Use Vaadin components: `Avatar`, `ComboBox`, `DatePicker`
+
+1. [x] Implement CRUD Operations
+
+    - <mark>Bind views to repositories</mark>
+    - Implement **Create, Read, Update, and Delete** operations in views
+
+1. [x] Styling and Layout
+
+    - Ensure responsive design
+    - Apply consistent styling across views
