1 Introduction
System design requires analysis of the key data structures and algorithms that will
be used to develop the system before the system specifications are implemented.
For the proposed inventory system there is need to analyse the most suited data
structures that can be used to store and handle the type of data that will be stored
by the system. This also applies for the algorithms that will be used to handle
different operations that will be handled by the system. This report presents a
discussion of the system analysis of the proposed inventory system including the
variables, keys and ranges that will be used in the system. The operations
supported by the system and their respective algorithms are discussed in depth
with a justification of why they are the best suited for the system. A discussion of
flexibility and scalability of the system is also discussed in the case where the
company decides to merge with another company leading to an increase in the
amount of data handled by the system.
2 Variables keys and ranges
To describe the variables keys and ranges of the system, we must understand the
structure of by modelling using OOP concepts. The proposed inventory system will
handle two types of products; food products and household products. A product can
be represented as a class having attributes and operations that identify a product.
The following classes define the variables that will be used by the system;
 Product class
Figure 1: Product class
The first row of the diagram is the name of the class which is product. The
second row of the class shows the attributes that define a product. These
attributes are;
