Now, this system is designed in such a way that it takes fewer resources to work properly. It has its own sort of minimum requirements that we need to take care of :

The system needs a minimum of 2 GB of ram to run all the features smooth and sudden.

It needs a minimum 1.3 GHz processor to rum smooth as less than that may create problems.

The system needs to be operated by some authorized person as wrong hands can make it irresponsible.

Rest is all up to the user’s usage will care for hardware

For security Antivirus is recommended.

The system has modules and classes to store every entity in a proper manner and needed to place in a proper manner so we need to have a proper design for that we put all of it in E-R diagram of this machine.

WIth this, every aspect of the system entities will be clear and gives a clear cut idea to code in sequence.

Entity User:

Every User detail needs to be stored in a proper manner with very needed attributed. So as it is very important with the view to monitor the particular customer’s likes and dislikes and further need to be given offers and gifts according to that to maintain the loyalty of the customers and retaining them for a long time.

In this world, the proper need of detail of the customer is required to deep analyze them accordingly. So we have the specific attributes of it as follows:

Primary key User_id:

The user id is system generated and unique, which can be referenced in any other entity.This mostly for recognizing it in the unique way anywhere in the program.

Now, this should be dealt in such a way that we can manage it is very easy and quick manner no complexion should be there for the processed to filter it according to a particular attribute or according to category and price too.

For that reason, we need to make it clear with it attributes to reference.

Primary key  Item_id:

This is system generated and is a unique one of the most useful attributes as we mandatory need this to reference it anywhere in the interfaces and clearly, show the data to the user interface and billing interface.

This is the most common and most popular way payment. Due to advantages of need not to carry cash it gained popularity. Pos machines are handy in this case on customer part.


If one does not have cards then he can always go for it but seems to become very old fashioned these days.


In this use case as you can see we have our system as box and the users who use our system are of the kind of outside the box but related to the system.

Users :

There are two types of users in the system who interact with the system.

Customer rep.:

Who punches data on the behalf of the customer into the system and responsible the billing and other data fed in the system.

Admin panel :

This is where admin can monitor every data and manipulate that too. Actually, he gases most powerful privileges granted by the developer.

Most of the case it is maintained by the higher authority where the system can be taken as security. The things Admin can are as follows:-

He can Login through his id and password. The password is made very secure so that no person can guess and make it difficult for hackers to crack.

He has access to the profile of his own and he can search detail of other Users and can see the detail of him.

He can add staff in that account and give access to managers for handling the reception on their own.

He can manipulate the data of any user.In this, we are showing here the interaction of the users with our system through our use case diagram.


The functional requirement of this 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:-

User data should be fed into the system:

This system is doing that properly in user entity.

Non-Functional of restaurant billing system source code:-

Non-functional necessities square measure the other demand than practical necessities. This square measure the necessities that specify criteria which will be wont to choose the operation of a system, instead of specific behaviours.

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 requirements of restaurant billing system source code 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 requirements of restaurant billing system source code 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 vice.Here we need to take care of few more things before heading towards the system.

The most important feature of 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.

Everything should be made distinctive by using the colour combination such that everything needed most frequently highlighted with focus colours. We can use simple layouts like card layout.

By varying colour combination many good intuitive interfaces can be made. Which ultimately makes interface easy to use for a long time.

Unlike ancient style wherever the goal is to form the thing or application physically enticing, the goal of interface style is to form the user’s interaction expertise as straightforward and intuitive as attainable – what’s typically known as user-centred style.

Where smart graphic/industrial style is daring and eye-catching, smart interface style is commonly delicate and invisible.

Keep things simple and consistent:-

Simple and Harmonic way making up is very intuitive and needs to followed

Make good use of typography:-

The typography is taken care very strictly as the need of the system.

Use colour and contrast properly:-

Color combo of lite and dark is good way emphasis and done well in this system

Consider feedback messages:-

The feedback form is a very good way taking feedback of forms and improving the system.

Simplified forms:-

The form is made simple to fill with the clean user interface.


Finally in restaurant billing system source code, the outcome of all the time hard work is here. We have a system which takes the necessary choices of the customer according to the various filter like price, category of the food and popularity ,

then he is able to place the order accordingly and then system calculate all the total of the order with taxes and then it can dispatch the bill that is handed over to customer.

Customer according to the choice pay bill via cash or debit card or credit card method. Hence all the process works perfect, full filling the demands.
