Answer 2

Answer: All of the things in the inventory database will be displayed using those databases. We will look up the vendor who can supply the item and display the vendor's contact information as part of displaying any given inventory item.

Explanation: We develop the Example Inventory Read programmed to accomplish this. This programmed reads all inventory data and displays them by:

opening the environment, then the database objects for the vendor, class directory, and inventory. Using the MyDbEnv class, we carry out this. This class is described in Stored Class Catalog Management with MyDbEnv.

using the inventory database to get a pointer.

systematically displays each entry as it moves through the database.

The custom tuple binding that we developed in InventoryBinding.java is used to show the Inventory record.

The vendor associated with the inventory object can be found using database. Get().

The Database Entry returned by the get() method is changed into a Vendor object using a serial connection.

The vendor object's elements are shown.
