The functional requirement of the electricity bill management system is that it does what it is meant for. A functional requirement describes what a software system should do, while non-functional requirements place constraints on how the system will do so.

Functional requirements specify a function that a system or system component must be able to perform. It can be documented in various ways. The most common ones are written descriptions in documents and use cases.

Few of its functional requirements are as given below:-

Non-functional necessities square measure the other demand than practical necessities. This square measure the necessities that specify criteria which will be wouldn’t to choose the operation of a system, instead of specific behaviors.

Non-functional necessities square measure within the style of “system shall be “, associate degree overall property of the system as a full or of a specific facet and not a particular operation.

The system’s overall properties remarkably mark the distinction between whether or not the event project has succeeded or unsuccessful.

Non-functional necessities – are often divided into 2 main categories:

Execution qualities, like security and usefulness, that square measure evident at the run time.

Evolution qualities, like liabilities, maintainability, flexibility and quantifiable, that square measure embodied within the static structure of the code.

Non-functional necessities place restrictions on the merchandise being developed, the event method, and specify external constraints that the merchandise should meet

Our project qualifies all the criteria of functional and non-functional accordingly and the system is up to mark performance vise.Here we need to take care of few more things before heading towards the system.

The most important feature of electricity bill management system application world is that application’s ease of usage .application will easy to use if made while keeping in mind that user need not think twice about searching any feature.
