Dependency of Waste Management System(SRS)
The waste management system in software development is dependent on a set of relations and entities that must be fulfilled to complete the entities and requirements of the SRS management system.
Entity-Relationship (ER) –
An ER is known as “Entity-Relationship” and it is the relation between two individuals who are part of the system. The ER is mainly explained with the help of the ER Diagram. When we talk about the waste management system, entities of the particular system include “Customer,” “Waste Collection Point,” “Waste Management Company,” “Waste Bin,” etc. The relationships between these individuals can be derived with the help of a diagram a “Customer” can establish a relationship with a “Waste Collection Point” which may show the place where they deposit their waste.
Class Diagram –
A class diagram is used to represent the fixed structure of a system, which shows the user the classes, attributes, methods, and relationships among them. When we talk about the waste management system, different classes can exist and they can also include “Customer,” “Wastebin,” “Collection Point,” “WasteManagementCompany,” etc. Each Attribute and method of each class is marked. I.e. the “Wastebin” class can have attributes like “location,” and “capacity,” and methods like “emptyBin,” and “check Capacity,” etc. Also, the relationships between these classes can be indicated with an association like a relationship between “Customer” and “WasteBin” indicates that a customer interacts with a waste bin.
Use Case Diagram –
A use case diagram is used to define the functionality of a system by showing the members included in it with the use cases and their relationships. The members of the use diagram are indirectly the users or the external systems that interact with the system. The Use cases are used to represent specific functions or tasks the system can perform. Examples of Use cases can be actions like “Registering for Waste Collection Service,” “Requesting Waste Collection,” “Managing Waste Collection Schedule,” etc.
Data Flow Diagram (DFD) –
A DFD helps the user to explain the flow of data within a system. It helps the user to know the direction of the data moving through processes and stores in the system. It is hierarchical and made up of multiple levels. When we talk about the waste management system, a DFD helps the user to know how waste collection requests flow from customers to the waste management company, it explains how scheduling information flows, the processing of data and then waste collection points are stored and accessed, etc. It can be used to represent the functions or transformations that occur within the system, such as “Schedule Waste Collection,” “Update Collection Point Information,” etc. The DFD also shows how the Data stores represent their data and then held within the system, such as databases or files containing information about customers, waste collection points, etc.
SRS of Waste Management System Project in Software Development
We as humans know better about waste, its harmful effects, and the importance of managing the waste to keep our communities clean and healthy. Similarly, we design and develop software multiple times according to our client’s needs and sometimes this process of requirement gathering and designing increases the waste. In today’s world, Waste Management Systems (SRS) for the software is very important because it not only helps users to design and handle a system but is also used to collect, transport, treat, and dispose the waste more efficiently.
