  • Developers
  • Project Testers
  • Marketing Department

• 1.3 Intended Use

• Developers: This SRS can be used by the developers. This SRS will help the developers to understand the overall project easily since this SRS gives a proper overview of the entire project. Developers also can understand in which part they should focus more, developers can also improve any part if needed. Also through this SRS, developers can easily understand the features which will help them to find out possible ways to modify any feature or to add new features to upgrade the project. • Project Testers: Testers can use this SRS to test the software as per requirements. Since this SRS is an overview of the entire project, so it will make the testing more organized and testers can easily get the idea where to look and what error or bug they should be looking for. • Marketing Department: Marketing departments promote projects. So they need to have knowledge about the project they are about to promote. Through SRS, the marketing department will be able to have an overview of the project which will eventually help them to promote the project.

Overall Description We are going to build a web application which will allow customers to buy their necessary products from home and will allow owners (sellers/providers) to sell their products. Thus it will be a common platform for service takers and service providers through which both of them can be benefited. This web application’s features will make ordering easier and also it will make it systematic and secured.

• 2.1 User Classes and Characteristics Three types of people can access in this software system: owners, customers and deliveryman. In this system, the shop owner has access to the information about the shop and has the ability to edit it. The shop owner will be able to see the supermarket's current order requests and will be able to accept or cancel them, as well as view all order information. They will have full control over their product information, which means they will be able to delete a product if it’s out of stock or add new products. Customers can examine and update their personal information in addition to ordering product items online. They can see which orders are pending as well as those that have been received.

• 2.2 User Needs In this corona pandemic situation, people have enough risk to go out. Sometimes government decides to lockdown the entire country. People have restrictions to go out but in every situation people have some demand on daily necessary thing. Thinking of people’s needs, we are primarily developing this web application as a solution to assist customers in conducting virtual shopping without having to leave their homes and people will get deliveries which will be fast and affordable. We take some survey’s that e-commerce software It takes a long time to deliver an order to a customer since a delivery man must first go to the store, purchase items, and then deliver the order, which appears to be a lengthy process that takes a long time. Since a result, we've developed a portable internet shopping system in which a vehicle carrying products will be stationed around the residential area, allowing clients to receive their orders faster than ever before, as the vehicle, which functions similarly to a shop, will arrive on the spot. First and foremost, customers should have a need for the information before consuming anything from the system. Our Web-application will include full information on the product, including pricing, availability, and the location of the real store. Searching for a Shop: Customers can search for a shop that is closer to them by entering their location. This will bring up all of the shop's details, including product availability. Customers can then place orders using their nearer shop personal id and product list. Customer information: The customer has access to his personal information. Orders received: Orders received by that customer up to this point will be displayed. Orders in progress: Until now, orders in progress have been displayed. Once the order has been completed, the order will be immediately shifted to the received order. Customer can update his or her information. Logout: The customer has the option to log out.

• 2.3 Operating Environment Operating environment for the Virtual Shop Management System is as listed below: • Operating system: Any kind of OS which supports browsing. • Distributed database: MySQL. • Back-end: Php. • Front-end: HTML, CSS, JavaScript.

• 2.4 Constraints: • We have to develop the application in PHP. • The developed system must work in the client’s operating environment, which is Windows. • We have to finish the project within 2 and half months. 2.5 Assumptions • Users have basic understanding of English. Since the user interface will be in basic English, so it is assumed that the user has a basic understanding of the language. • Users will have electronic devices and internet access. Because virtual shopping will be a web-based platform, accessing the website will necessitate a strong internet connection. Thus it will be presumed that the users have adequate internet access. Also, because smart phone access will be required, it is presumed that the user is comfortable with smartphone usage. • Users have basic knowledge about browsing.
