- What is data binding in software development, and why is it important for creating dynamic user interfaces?A new sales ordering system needs a relational database that contains a customer table, a product inventory table, and an order table. Use a word-processing, graphics, or spread-sheet program to draw an entity-relationship diagram showing the relationships among these entities. Next, design each of these tables showing the keys and attributes to be included in each table. Include five sample records for each table.How important is the Model-View-Controller (MVC) pattern to the overall process of creating web-based programs? Discuss the benefits of using an MVC framework and how they may be put to use.
