Hotspot Enta Video Rental System SYSTEM REQUIREMENTS SPECIFICATION (SRS) Version 1.0Produced for:Hotspot Enta.P.O BOX 404-00100,Nairobi.Produced by:Stephen N. Muindi CS 282-2144/2010James Mahindu CS 282-2123/2010
Executive OverviewThe Hotspot Enta (HES) system will be a global Web-based marketplace bringing together privateindividuals and small companies to buy and rent movies and video games. It will take advantage of theInternet and World Wide Web to radically improve the way they buy and rent items.The customer objectives for the HES are to: Provide them with a huge selection of items (and sellers). Enable them to easily search for, find, and buy the items they want. Enable them to buy items that they could not ordinarily find or afford. Enable them to help set (and thereby minimize) the price of the items they wish to buy (e.g., via promotions). Make buying more convenient by allowing them to buy items: Anytime (i.e., 24 hours a day and 7 days a week). Anywhere that the buyers have access to the Internet (e.g., at home, at work, and while traveling). Minimize risks associated with buying over the Internet.The seller objectives for the HES are to: Provide them with a huge customer base of potential buyers. Enable them to easily target and personalize their marketing to appropriate potential buyers. Enable them to sell items that they could not otherwise afford to sell (e.g., by minimizing their overhead and transaction costs). Enable them to determine the market price of their items and set their prices accordingly (e.g., via auctions or direct sales). Make selling more convenient by allowing them to sell items: Anytime (i.e., 24 hours a day and 7 days a week). Anywhere the sellers have access to the Internet (e.g., at home, at work, while traveling). Minimize risks associated with selling over the Internet.The HESC objectives for the HES are to: Minimize the costs of providing a marketplace (e.g., capital costs, labor costs) compared to a physical marketplace (e.g., a shopping mall) by maximizing automation and thus minimizing labor and facilities costs. Maximize income by maximizing the number of sellers (i.e., movie production houses) paying marketplace fees.
INTRODUCTIONThe video rental industry is an ever evolving industry that changes with the economy, evolution of cultureand technology ant to remain viable in the business, the clients must be willing to evolve. The aid of thecomputer and a system that is fully computerized, user- friendly, time efficient and well organized, isindeed very useful in realizing this quest.BACKGROUND AND OVERVIEWA growing video store business called “Hotspot Enta” is looking to expand its chain of stores and whenthe business was started the client did not account for such rapid growth in the market place. As a resultthe existing software will not scale of perform to the expectations of its business needs.“Hotspot Enta” requires an online software system that will manage all aspects of rental, sales, customersand inventory. They require that this information be stored in a central repository and can be updated, andaccessed from any of its stores.When a new customer visits the system he should be able to watch movie trailers and their reviews andratings, search movies and browse through some categories. However, in order to rent a movie he has tosubscribe for a membership. The customer should be able to receive the movie by post. In addition, thecustomer should be able to see his rental history and also receive an email newsletter from the system,containing news about movies and new DVD releases.STEPSThe above scenario is briefly shown in the following steps: 1. Customer subscribes for membership by providing personal information and credit/debit card information. 2. Customer browses the product and can add a movie to be rented into a wish list. 3. The movie will receive the movie by post. 4. After watching, the customer can send it back. 5. After receiving it the system will send another movie from the wish list.The following stakeholders are identified in our online rental system: 1. Customer-A person who subscribes for a membership in order to rent DVD. 2. Employee-Who here is Hotspot Enta, who offers the rental services. 3. DVD Store-Where the DVD is housed to be sold or rented. 4. Post Office-A post office that provides delivery services. 5. Financial Institutional-Bank or Credit card companies that provide financial services to customer or DVD store. 6. Supplier-A wholesaler that supplies DVDs/cassettes to the DVD store.
Some of the problems that this customer currently has as a result of its existing software solution, apartfrom the obvious that it hinders their plant to expand are; 1. No central repository where information can be accessed easily and quickly 2. Manually updating a central database on a weekly basis will tie up a resource for hours per week at least. 3. The response times of the current software solution is at a critical poor level. Often customers are left standing at the counter with a clerk while the clerk waits for the customer information to appear on the screen.Some of the tasks we will engage in during this project are as follows; Become familiar with the current system. Develop supplementary specifications. Examine all function requirements. Develop vision. Bring forth stake-holder requests. Structure. Come up with new system.AIMS AND OBJECTIVES By implementing our system, the owner will have a competitive advantage over other video stores and agreater overall productivity in terms of sale. Our proposed video rental system aims at achieving thefollowing: 1. Developing a new system better than the current system. 2. Manage to build-up a friendly environment to customers. 3. Enlarge the marketing of video rental to near-by towns. 4. To create a movie rental store whose goal is to exceed customer expectations.The primary objective of this project is to address the common problems which a video rental systemexperiences. The objectives include: - Ensuring that the rental system is in the real time performance - Increase the number of customer by 5% by the end of the year
RESOURCESIn order to achieve coming up with a new system we’ll need the following resources; 1) A Computer. 2) SQL Server for data storage. 3) Programming language like Visual Studio 2010 for developing the software.CONSTRAINTSThe constraints define the boundaries of the work, which may include resources, budget and anystandards to be adhered to. The main challenges that would/might be experienced may include: 1. If the central repository crashes all data and information will be lost. 2. Access right is limited only to a few. 3. The storage memory for the database is limited.FEATURESThere are various advantageous features of the online video rental system and some of them are givenbelow: 1. Account and invoicing management. 2. Inventory management. 3. Track transaction history and user profiles. 4. Facility to import old data. 5. Customize reports generation and printing facility. 6. Easily customizable system.All these features will make it very simple to run the video store. The effective proceeding will increasethe chances of getting new business. The online rental system will provide the users a very uniquebrowsing experience. In just a single click the user can discover the recommended movies and thereviews about the particular movie in seconds. The user is given various admin rights where he/she canchange the priority the movies to be delivered to him. Another advantageous feature is that the user canmake payment through their credit cards as well.
Functional specificationFunctional specification is like documentation and it explains the expected features of theproposed system. In addition this document further explain the sub functions of the system suchas customer registration, purchase movie, Sell a movie, Rent a movie, Return. Etc.Functional requirementsStaffs must be able to create login account and register and also be enable to do add or editfunctions, and must be disabled for data delete function.Here are the major functionalities according to the staff’s requirements. 1.
