II. Project Description Parts Catalog This project builds a parts catalog using a B-tree for storage. Introduction: Today a parts catalog would be built using a database for storage. Databases are very versatile in their ability to store and retrieve data. In this project, you will build a parts catalog system as a single-user system without the use of a database. Instead, you will create a B+-tree and store the parts data in it. Overview: This project consists of two parts: a B+-tree for storing parts data and a user interface for accessing the data. These two parts should be independent, so that changing to another storage system or another user interface is not too difficult. Your project should allow the user to maintain a parts catalog. A flat-file of part data will be provided. Your program should begin by loading data from the flat-file into a B+-tree. Once loaded, the user can query for a particular part number, display the next 10 parts, modify the description of a part, add…
