Chapter 10. Editing the Stock Information

In the previous chapter, we learned how to add a MasterProduct Entity to our existing Data Model for storing information of the products (master product) that the vendor deals with. We learned that for maintaining the information of the master product, that is, for displaying, adding, deleting, and modifying the master product's information, four modules were required. Out of these four modules, we learned how to develop the first two modules:

  • Developing the View to enter the master product's information

  • Developing the MasterProduct's menu to add, delete, and display the information of master products

In this chapter, we will learn how to develop the third and fourth modules required for maintaining the master product's information. The two modules are:

  • Module to connect the MasterProduct's menu to the rest of the project

  • Module to modify the information of the master product

Let us proceed to create the third and the fourth modules.
