[[Srs]] online shopping website for TYBSC IT
- 1. Practical No : 1 Aim : Online Shopping Website 1 . INTRODUCTION The Shopping Cart program allows visitors to your on-line shopping site to collect items in a virtual shopping cart. They may view the contents of their shopping cart at any time and may add or delete items at will. The program automatically calculates the subtotal, sales tax, shipping charges, and grand total. When a visitor decides to check-out, the order information including the buyer's name, address and billing instruction is e-mailed to your order department (or whomever you choose) and a receipt is sent to the shopper. This is software which helps you to do the major part of online shopping by using this site and can be managed by online; you (or the Customer) can do the all major transaction in a secured way. Here the customer will feel a virtual shopping by adding the selected product to his cart in addition to that; he can also does bulk addition into the cart before purchasing. This all options are done by session management. To ensure the authentification of the customer, He/She must have to register before proceeding. It provides following standard features of any e-commerce web site: 1.1 PURPOSE Simple systems allow the offlineadministration of products and categories. The shop is then generated as HTML files and graphics that can be uploaded to a webspace. These systems do not use an online database. A high end solution can be bought or rented as a standalone program or as an addition to an enterprise resource planning program. It is usually installed on the company'sown webserver and may integrate into the existing supply chain so that ordering, payment, delivery, accounting and warehousing can be automated to a large extent. Other solutions allow the user to register and create an online shop on a portal that hosts multiple shops at the same time. Open source shopping cart packages include advanced platforms such as Interchange, and off the shelf solutions as Avactis,Satchmo, osCommerce, Magento, Zen Cart, VirtueMart, Batavi and PrestaShop. Commercial systems can also be tailored to ones needs so that the shop does not have to

Other establishments such as internet cafes and schools provide access as well. A visit to a conventional retail store requires travel and must take place during business hours. Searching or browsing an online catalog can be faster than browsing the aisles of a physical store. One can avoid crowdedmalls resulting in long lines, and no parking. Consumers with dial-up Internet connections rather than broadband have much longer load times for content-rich websites and have a considerably sloweronline shopping experience. Some consumers prefer interacting withpeople rather than computers because they find computers hard to use. Not all online retailers have succeeded in making their sites easy to use or reliable. On the other hand, a majority of stores have made it easy to find the style one is looking for, as wellas the price range that is acceptable making the shopping experience quick and efficient. The internet has made shopping an almost effortless task. 1.3 DEFINATIONS, ACRONYMS, ABBREVATIONS Class diagram: Shows a collection of static model elements such as classes and types, their contents, and their relationships.

SOFTWARE DEVELOPMENT METHODOLOGY Software engineering is the practice of using selected process techniques to improve the quality of a software development effort. This is based on the assumption, subject to endless debate and supported by patient experience, that a methodical approach to software development results in fewer defects and, therefore, ultimately provides SRS System Requirement Specification BRD Business Requirement Document URD Use-case Requirement Documentation SC Shopping cart CUST Customer SP Sales person WHE Warehouse employee LI LOGIN LO LOGOUT REG Register VP View products PO Placeorder MP Make payment CP Change profile RO Receive order VP Verify payment PB Print-In-Voicebills NW Notify warehouse about order VR View new registrations MNGP Manage products information online(i.e., Update , Delete, Create) US Update order status online CS Check delivery status online SDLC System Development life cycle SFD System feature documentation
- 5. shorter delivery times and better value. The documented collection of policies, processes and procedures used by a development team or organization to practice software engineering is called its software development methodology (SDM) or system development life cycle (SDLC). All projects can be managed better when segmented into a hierarchy of chunks such as phases, stages, activities, tasks and steps. In system development projects, the simplest rendition of this is called the "waterfall" methodology, as shown in the following figure: In looking at this graphic, which was for major defence systems developments, please note this presumes that the system requirement have already been defined and scrubbed exhaustively, which is probably the most important step towards project success. Nevertheless, the graphic illustrates a few critical principles of a good methodology: Work is done in stages, Content reviews are conducted between stages, and Reviews represent quality gates and decision points for continuing. The waterfall provides an orderly sequence of development steps and helps ensure the adequacy of documentation and design reviews to ensure the quality, reliability, and maintainability of the developed software. While almost everyone these days disparages the "waterfall methodology" as being needlessly slow and cumbersome, it does illustrate a few sound principles of life cycle development. 3 SYSTEM ANALYSIS 3.1 STUDY OF THE EXISTING SYSTEM
- 6. In existing system shopping can done in a manual way, the customer has to go for shopping, and then he is having the possibility to choose the products what ever he wants. It is a time consuming process. Thus, the system has to be automated. 3.2 PROBLEMS IN EXISTING SYSTEM In Existing System the Customer is completely depending on the manual process for buying the products. Manual process is a time consuming factor. And when customer approaches for a manual shopping directly, actually he/she does not have an idea about things like, price range, items, etc., The time which has been spent by the customer in manual shopping can equates to multiple number of shopping. As customer can sit at home and browse in a fraction of seconds. Thus we need to change to a system like “Online Shopping “. 3.3 PROPOSED SYSTEM Sends receipt to customer Accommodates up to four types of shipping Allows owner to predefine sales tax based a specific state Tracks purchases even if user clicks the back button Tracks each customer by Shopper ID (SID) (does not use cookies) 3.4 REQUIREMENT SPECIFICATION 3.4.1 FUNCTIONAL REQUIREMENTS System should have a provision for customer to view/order products. System should have a facility for sales person to update the products & order details. System should allow the sales person to create/update/delete invoice bills.
- 7. System should have a provision for warehouse employee to create/delete products information. System should facilitate the ware house employee to view information about customers. 3.4.2 NON – FUNCTIONAL REQUIREMENTS The users of the system should be provided user id and password along with the well defined access privileges. 24X7 internet connectivity should be provided for well functioning of the system. Systems should be provided with proper backup media and resources to handle system crash scenarios. 4. FEASIBILITY STUDY Preliminary investigation examines project feasibility; the likelihood the system will be useful to the organization. The main objective of the feasibility study is to test the Technical, Operational and Economical feasibility for adding new modules and debugging old running system. All systems are feasible if they are given unlimited resources and infinite time. There are aspects in the feasibility study portion of the preliminary investigation: Technical Feasibility Operation Feasibility Economical Feasibility 4.1 OPERATIONAL FEASIBILITY Proposed projects are beneficial only if they can be turned into information systems that will meet the organizations operating requirements. Simply stated, this test of feasibility asks if the system will work when it is developed and installed. Are there major barriers to implementation? Here are questions that will help test the operational feasibility of a project.
- 8. Is there sufficient support for the project from management from users? If the current system is well liked and used to the extent that persons will not be able to see reasons for change, there may be resistance. Are the current business methods acceptable to the user? If they are not, Users may welcome a change that will bring about a more operational and useful systems. Have the user been involved in the planning and development of the project? Early involvement reduces the chances of resistance to the system and in general and increases the likelihood of successful project. Since the proposed system was to help reduce the hardships encountered. In the existing manual system, the new system was considered to be operational feasible. User-friendly Customer will use the forms for their various transactions i.e. for adding new routes, viewing the routes details. Also the Customer wants the reports to view the various transactions based on the constraints. Theses forms and reports are generated as user- friendly to the Client. Reliability The package wills pick-up current transactions on line. Regarding the old transactions, User will enter them in to the system. Security The web server and database server should be protected from hacking, virus etc Portability The application will be developed using standard open source software (Except Oracle) like Java, tomcat web server, Internet Explorer Browser etc these software will work both on Windows and Linux o/s. Hence portability problems will not arise. Maintainability The system called the ewheelz uses the 2-tier architecture. The 1st tier is the GUI, which is said to be front-end and the 2nd tier is the database, which uses My-Sql, which is the back- end.
- 9. The front-end can be run on different systems (clients). The database will be running at the server. Users access these forms by using the user-ids and the passwords. 4.2 TECHNICAL FEASIBILITY Evaluating the technical feasibility is the trickiest part of a feasibility study. This is because, at this point in time, not too many detailed design of the system, making it difficult to access issues like performance, costs on (on account of the kind of technology to be deployed) etc. A number of issues have to be considered while doing a technical analysis. Understand the different technologies involved in the proposed system: Before commencing the project, we have to be very clear about what are the technologies that are to be required for the development of the new system. Find out whether the organization currently possesses the required technologies: Is the required technology available with the organization? If so is the capacity sufficient? For instance- “Will the current printer be able to handle the new reports and forms required fort the new system?” The technical issue usually raised during the feasibility stage of the investigation includes the following: Does the necessary technology exist to do what is suggested? Do the proposed equipments have the technical capacity to hold the data required to use the new system? Will the proposed system provide adequate response to inquiries, regardless of the number or location of users? Can the system be upgraded if developed? 4.3 ECONOMICAL FEASIBILITY Economic feasibility attempts to weights the costs of developing and implementing a new system, against the benefits that would accrue from having the new system in place. This feasibility study gives the top management the economic justification for the new system.
- 10. A simple economic analysis which gives the actual comparison of costs and benefits are much more meaningful in this case. In addition this provides to be a useful point of reference to compare actual costs as the project progresses. There could include increased client satisfaction, improvement in product quality better decision making timeliness of information, expediting activities, improved accuracy of operations, better documentation and record keeping, faster retrieval of information, better employee morale. The computerized system takes care of the present existing system’s data flow and procedures completely and should generate all the reports of the manual system besides a host of other management reports. It should be built as a web based application with separate web server and database server. This is required as the activities are spread through out the organization customer wants a centralized database. Further some of the linked transactions take place in different locations. Open source software like TOMCAT, JAVA, Mysql and Linux is used to minimize the cost for the Customer. 5 SYSTEM REQUIREMENT STUDY 5.1 SOFTWARE REQUIREMENTS Technology : ASP.NET with Ajax Programming Language : C#.NET Database : SQL Server Tool : Rational Rose Application Server : IIS 5.2 HARDWARE REQUIREMENTS Pentium IV processor 1 GB RAM 80GB HDD
