framework of e commerce notes

The sender determines a secret value a. When a user clicks on a link to a web page, the connection is opened, data is transferred and the connection is broken.Request- response protocol that allows different platforms and applications to exchange documents. The first mode, connection-oriented, transmits the entire message in a data stream, connection is established, the data is transferred, error checks are performed and receipt of data is confirmed, and the connection is closed. This search would require several queries to various online directories to find empty seats on various airlines and then the availability of seats would be co-ordinate with the amount of time spent in the airport terminals. this is called reliable protocol since delivery of all guaranteed, if packets get lost along the way, they are automatically resent. Interactive catalogs are the customized interface to consumer applications such as home shopping. How do you use it? It allows the user to access and read mail directly from the server without having to download it. Symmetric encryption keys: In symmetric key system, both the sender and the receiver of the message must have access to the same key. Messaging is gaining momentum in electronic commerce and have many advantages. TOPIC 1: E-COMMERCE FRAMEWORK, BUSINESS MODELS AND ENVIRONMENT 1.1 Define electronic commerce (EC) and describe its various categories. Thereafter, SSL's only role is to encrypt and decrypt the message stream. Configuration, Product management, Marketing & Design, Technology & Storefront, Internationalization, PayPal Extensibility, manufacturer support, extendable via plugins, product Streams. SSL: SSL is layered beneath application protocols such as HTTP, SMTP, TELNET, FTP Gopher and NNTP and above the internet connection protocol TCP/IP. These elements are classified as different layers as per the framework given by Center for Research and Electronic Commerce (CREC) at the University of Texas in the… E-Commerce could even result in a breakdown of human relations because of all the transactions being carried out through the internet. SHEN: is a security scheme for the web sponsored by the W3 consortium. This means that multiple encryption/decryption need not be done at very intermediate point. It addresses the issue of adding value to the information that is retrieved. such data might include algorithms. After giving the remote host, userlD, and password information to the software, it will log onto the desired system and show the local directory in one window and the remote directory in another window. The data link and network layers can operate in one of two nodes. Several cryptographic message format standards can be incorporated into S-HTTP clients and servers. E Commerce by Vardhman Mahaveer Open University. a framework for developers to build outstanding e-commerce solutions for customers, with a native integration into Pimcore, with a component based architecture; and a strict separation between backend functionality and frontend presentation. Conceptual Framework Internet economy is a broader term which includes both e-commerce and e-business. SECURITY ENHANCED MAIL PROTOCOLS: Some commercial e-mail services use a protocol called requires that e-mail be sent along paths with only known, trusted e-mail carriers, such as AT&T and MCI. “ ...Perhaps the single most important thing … Architectural Framework of E Commerce. A structured document messaging consists of the automated interchange of standardized and approved messages between computer applications, via telecommunications lines. 4. Secure Messaging and Structured document Interchange Services: The importance of the fourth layer is secure messaging. 2. An encryption process that uses a block cipher technique takes a fixed block text 64bits. By harnessing the power of the internet, electronic commerce has changed the way in which organisations conduct business. OSI: A general reference model for the standardization of data communication procedures that support interoperability is the ISO Open Systems Interconnections (OSI) model released in 1984. Software agents are used to implement information brokerages. SSL provides a security "handshake" to initiate the TCP/IP connection. Clients may initiate a secure transaction, typically using information supplied in HTML fill out forms. When conditions changed along with hardware and the software the organizations couldn't cope. The benefit of SSL over S-HTTP is that SSL is not restricted to HTTP, but can be used for security for FTP and TELNET, among other Internet services. DEPT OF CSE & IT ... processes and interactions within the entire government framework. 2016/2017. For each approved study note you will get 25 Credit Points and 25 Activity Score which will increase your profile visibility. They examine themselves and their environment and if necessary change from their original course of action to an alternative plan. 5. Placement on EP Framework. define the general program flow; consist of reusable components; be organized in functional domains; Examples of e-commerce frameworks are. One person can start the form, mail it to the next person, fill it, mail it to the next, and so on. An e-commerce framework must. It defines actually how e-commerce implemented, how online trading or business can be done. Security, privacy and confidentiality through data encryption and authentication techniques are important issues that need to be resolved for ensuring the legality of the message based transactions. The Framework of Standards establishes basic standards for cross-border e-commerce. Class B: This class is used for medium sized networks. This protocol runs on top of the TCP protocol. The relationships among them are probably best described graphically in figure. E-Commerce (CS101) Uploaded by. Business-to-Business Transaction: We call this category market-link transaction. The following figure shows the components involved in E-commerce infrastructure. Unstructured messages consist of fax, e-mail and form-based systems like lotus-notes. The full memo can be found at the GIPI website, http://www.internetpolicy.net/. FTP is a common tool used for uploading web documents to a server. Messaging is well suited for both client-server and peer-to-peer computing models, distributed systems, the messages are treated as "objects" that pass between systems. This is a stateless protocol. Examples are electronic mail, enhanced fax, and electronic data interchange. In current retail market and environment, it is highly considered that your business is spread all across global and though it is possible to get done through managing products, listings and orders in a multi-channel environment. Network Layer: The layer performs data routing and delivery across multiple nodes. The key framework feature which are vital for eCommerce businesses are: This is one of the functions which play a very big role in the market with search functions that helps in conversion rates. You can … Currently this protocol with PEM and PGP uses local key files on the server side. This protocol eliminates the need to maintain multiple preferences and address book files. University of Rajasthan. To provide security, the Netscape Navigator supports a new URL access method, https, for connecting to HTTP servers using SSL. NNTP: One of the great benefits of the Internet is the ability to easily share information. Define the general program flow; Consist of reusable components; Be organized in functional domains; Examples of e-commerce frameworks are. That is the idea behind the E-Commerce Framework of Pimcore. The transport layer basically masks the underlying transport mode and handles data reliability and integrity checks. Several methods can provide security in the web framework. By business we mean such features/components as quality of the product or service, pricing, time of delivery, customer service and differentiators from the competition. Aimeos … The next seven bits represent the network identifier. It includes 15 short, concise standards, which on the one hand are intended to simplify the harmonization of processes and on the other hand still leave enough freedom for pragmatic and innovative solutions in regard to national differences and concerns. IT & Computer Subjects, Computer Science, IT, BBA ... Factors Influencing The Consumer Perceptions To Buy Online. Architectural Framework For Electronic Commerce The software framework necessary for building electronic commerce applications is little understood in existing literature. Briskon e-Commerce framework is a strategic business framework to bring your business online. E-commerce is the buying and selling the goods and service through digital communication. The framework of e commerce is designed in such a way that It offers more flexibility when surfing from one page to another. E-Commerce frameworks are flexible enough to adapt them to your specific requirements. S-HTTP: Secure HTTP supports a variety of security mechanisms to HTTP clients and servers, providing the security service options appropriate to the wide range of potential end uses possible on the web. Academic year. The basic DES encryption steps are : 1. FTP: A popular method for uploading and downloading files is the file transfer protocol (FTP). This protocol allows users to search for specific topics of interest. It is the system which makes your website unique in searches across the global markets. One of the objectives of e‐Business is to provide seamless connectivity and integration between business processes and applications external to an enterprise and the enterprise’s back office applications sucha as billing, orger processing, accounting, inventory and receivables, and services focused to total supply chain management and partnership including product development, fulfillment, and distribution. Agents are encapsulations of users instructions that perform all kinds of task in electronic marketplaces spread across networks. Is known as message enabled work- flow solutions. Aimers (Laravel, Symphony, Typo3, Flow) Spyker (Symfony only) Sylius (Symfony only) The key framework feature which are vital for eCommerce businesses are: 1) Quality Search Functionality Sorry, your blog cannot share posts by email. This process uses an algorithm based on the senders and receivers and private information figure illustrates the following steps: 1. Transparency is accomplished using middleware that facilitates a distributed computing environment. S-HTTP does not require client-side public key certificates. For instance, buying an airline ticket with several stopovers with the caveat that the time between layovers be minimized. A classic example of a directory is the telephone white pages, which allows us to locate people and telephone numbers. In other words, SSL provides encryption that creates a secure channel to prevent third parties on the network from being able to tamper with and read message being exchanged between the client and server and authentication that uses a digital signature to verify the legitimacy of the server. Security and confidentiality are essential, before businesses can conduct financial transactions over the internet, and a lack widespread security measures remains at this time. This note covers the following topics: E-Commerce, E-Business, Social Networking, Mobile Commerce, Internet and E-Commerce Statistics, E-Commerce Models, E-Commerce Business Planning, E-Commerce Infrastructure, Design and Build Mobile Sites and Apps, E Commerce Security and Payment Systems, Netflix, E-Commerce Marketing Communications and E-Commerce … When it comes to managing the data, it is mandatory to get precise and accurate details over the data. The other 16 bits represent the hosts on each network. The data, while iin this unreadable form, is commonly referred to a cipher text. During its implementation it became a public key method. The other 8 bits represent the hosts on each network. Messaging is the software that sits between the network infrastructure and the clients or electronic commerce applications, masking the peculiarities of the environment. Client's conversation with the server is private (privacy using encryption). The electronic commerce application architecture consists of six layers of functionality or services : (1) applications (2) brokerage service, data or transaction management (3) interface and support layers (4) secure messaging, security, and electronic document interchange (5) middleware and structured document interchange and (6) network infrastructure and basic communication services. helpful 320 32. Electronic commerce: a conceptual framework Application services Brokerage and data management Interface Layer Secure messaging Middleware service Network Infrastructure Consumer-to-Business Transaction: Customer-to-business Business-to-Business Intra-organizational Order processing mail order houses Payment schemes electronic cash Clearing house or virtual mall Interactive catalogs Directory support functions Software agents Secure hypertext transfer protocol Encrypted e-mail, EDI Remote programming (RFC) Structured documents (SGML,HTML) Compound documents (OLE, Open Doc) Wireless cellular, radio, PCS Wire line-POTS, coaxial, fiber optic We call this category market place transaction. Proposals for Strategic Improvements. Physical Layer: This layer performs the physical transfer of bits transfer of bits transmission medium, it is the data communication interface with the hardware. Basically this function is kind of filtering which processes keywords and helps you to get precise effect over search and into your sales too. TCP operates at the transport layer of the OSI model, while IP operates at the network layer. Comments. Confidential data: contain material that is secret but whose existence is not a secret. Basically, it is a communication protocol used to connect internet hosts. If you have your own Study Notes which you think can benefit others, please upload on LearnPick. At destination, the datagrams are collected and reassembled and any lost packets are identified. It acts as a central clearing house for storing messages until they are retrieved and downloaded. Messaging is central to work-group computing that is changing the way the business operate. E Commerce and Business Technology. With the growth of networks, client-server technology, and all other forms of communicating between/among unlike platforms, the problems of getting all the pieces to work together grew from formidable to horrendous. The public key method allows a sender and a receiver to generate a shared, secret key over an insecure telecommunication line. We use the notion of information brokerage to represent an intermediary who provides service integration between customers and information providers, given some constraint such as a low price, fast service or profit maximization for a client. It performs tasks as converting messages into the necessary format for use by the application. In business electronic messaging is a critical issue. E-Commerce framework architecture. Middleware Services: Middleware is relatively new concept that emerged only recently. Electronic Commerce Application Secure Hypertext Transfer Protocol(SHTTP) TCP based application protocol Secure Socket Layer (SSL) Internet Protocol ('P) Fig: Web Security Layers The server implements server-side support for HTTP over SSL, including support for acquiring a server certificate and communicating securely with SSL-enabled browsers. Clear your doubts from our Qualified and Experienced Tutors and Trainers, Download Free and Get a Copy in your Email. For DES. Class A: This class is reserved for organizations with vary large networks, like IBM, and they are setup so that they can accommodate a large number of hosts. One advantage of S-HTTP is that is supports end-to-end secure transactions. Another advantage of messaging is that it is not associated with any particular communication protocol. IP Addresses: When a message is sent, IP address for both the sending and receiving nodes must be known. Client's conversations cannot be tampered or interfered with (data integrity) Categories of Internet Data and Transactions: several categories of data must be encrypted, making internet data security an interesting challenge. The next 14 bits represents the network identifier. 6. The client side with PEM uses the finger program to retrieve the server's public key, PEM or PGP encryption will need to communicate before hand and find a secure way to exchange their public keys 5.Explain the various Encryption techniques. These include the following: S-HTTP: is a revision of HTTP that will enable the incorporation of various cryptographic message formats, such as DSA and RSA standards, into both the web client and the server, most of the security implementation will take place at the protocol. With the messaging tools, people can communicate and work together more effectively-no matter where they are located. A is made public The receiver determines a secret value b A related value, B, is derived from b. At present, credit card numbers, financial records, and other important information are not encrypted and can be intercepted by any internet hacker. This is typically implemented with an encrypt-decrypt-encrypt, where two keys are used, not three. Interface and support services: The third layer, interface and support services will provide interfaces for electronic commerce applications such as interactive catalogs and will support directory services-function necessary for information search and access. The lack of details about the algorithm may also impact its commercial success RC2,RC4, RC5: Some alternatives of DES have been developed by private organization, such as RSA data security's RC2, RC4,RC5 all of which are creation of Ronald Rivest. Another protocol, Privacy Enhanced Mail (PEM), was put forth by IETF and the IRTF in late 1980s. Finalized E-commerce Preparedness Framework based off of position papers. Secret data: existence is a secret. They offer an environment for building e-commerce applications quickly. And transform the 64bit block to text into a 64bit block of cipher text. First, basic e-mail store and forward and remote server protocols were introduced and security related protocols are introduced. Clients are confident about servers they are communicating with (server authentication). The E-Commerce Package includes the Framework of Standards on cross-border e-commerce as well as documents supporting its implementation. A one-zero in the first two bits represents this class. It discusses the existing legislative framework of the Digital Single Market as well as the technology-driven changes of market and economy that have taken place over the last twenty years. The last three layers are called the upper layers because they deal more with message handling of the data packets transferred. A one-one-zero in the first three bits represents this class.

E-commerce-notes-pdf-lecture-notes-university-level. The agents are intelligent because they have contingency plans of action. Conceptual Framework of E- commerce Framework tells about the detail of how ecommerce can take place. Course. 1. A virtual network a collection of work-group, departmental, enterprise and inter-enterprise LAN's that appears to the end user or client application to be a seamless and easily accessed whole. 3. It supports both synchronous (immediate) and asynchronous (delayed) message delivery and processing. Three major components of market-driven transactions are customer orientation through product and service customization, cross-functional co-ordination through enterprise integration, and advertising, marketing and customer service. The IP addresses are 32 bits in length, decomposition of IP addresses varies according the assigned class. The aim of the architectural framework itself is not to build new database systems, data repository, computer languages, software agent based transaction monitors, or communication protocols. It negotiates packet recovery and provides synchronization check points for data packets transmitted. allow replacing all parts of the framework code; forbid changes in the framework code itself; contain bootstrap code to start the application; be extensible by user-written code; E-Commerce frameworks should. Some collaborative workgroup software, such as Netscape's Collabra, is built to be compatible with NNTP-compliant servers so that interactive discussion group session can be held. E COMMERCE SCCE_CSE Page 2 B.Tech IV/CSE II nd semester Term: 2010-2011 SYLLABUS UNIT-1: Introduction, Electronic Commerce Framework, the Anatomy of E-Commerce This class can only represent 256 host computers on a network. Class C: This class is used for small networks. Transport Layer: This layer provides data reliability and integrity checks of the data received by the ultimate end node. Network News Transfer Protocol (NNTP) is an IETF standard that is explained in its basic form in RFC 977. An interactive catalog is an extension of paper based catalog and incorporates additional features such as sophisticated graphics and video to make the advertising more attractive. The primary difference between the two is that unlike interactive catalogs, which deal with people, directory support services interact directly with software applications. Triple encryption: The strength of DES encryption is generally thought to be increased by using triple encryption. University. mail for purchasing goods and services, buying information and consulting services, submitting requests for proposals, and receiving proposals. A framework is intended to define and create tools that integrate the information found in today’s closed systems and allows the development of e-commerce applications. Information brokerage does more than just searching. E-commerce is an important element in the manufacturing industry such as MODENAS for them to participate in the worldwide markets globalization. The encoded message- the cipher text is unintelligible to anyone intercepting the message. The message is decrypted by reversing the procedure. The mail can be managed directly on the server by having a remote file server connection. This gives users and applications transparent access to data, computation, and other resources across collections of multi-vendor, heterogeneous systems. It is much stronger than DES since it employs an 80-bit key, and instead of scrambling the data 16 times, it scrambles it 32 times. Nupur Khandelwal. Encryption techniques: Confidentially of electronic messages is a necessity of electronic commerce application the primary method of achieving confidentiality is encryption. The second mode, connectionless splits the message into packets or datagrams and sends them intermittently to the destination. A windows version of FTP, WinFTP, makes file transfer procedures trivial. Integrate messaging is a group of computer services that through the use of a network send, receive, and combine messages, faxes and large data files. Information Brokerage and Management: The information brokerage and management layer provides service integration through the notion of information brokerages, the development of which is necessitated by the increasing information resource fragmentation. Usually, they make heavy use of interfaces and design patterns like. This is one of the features which highly impact over the website as speed key to efficiency. The main disadvantages of messaging are the new types of applications it enables-which appear to be more complex, especially to traditional programmers. It also performs error detection and control functions. A related value A, is derived form a. Hardware: This handshake results in the client and server agreeing on the level of security they will use and fulfills any authentication requirements for the connection. To achieve data centric computing, middleware services focus on three elements: transparency, transaction security and management and distributed object management and services. Explain the messaging protocols over the internet? Security socket layer (SSL): uses RSA security to wrap security information around TCP/IP based protocols. Please enter the OTP sent to your mobile number: Post an enquiry and get instant responses from qualified and experienced tutors. This presentation is based on a memorandum written by James Dempsey, the Global Internet Policy Initiative’s chief lawyer. The primary security features of PEM are: • Origin authentication and non-repudiation • Message integrity and • Message confidentiality PEM was incompatible with the rapidly emerging multi-media Internet protocol, Multipurpose Internet Mail Extension (MIME) and this in compatibility seriously impeded PEM's commercial success. A framework is intended to define and create tools that integrate the information found in today's closed systems and allows the development of e-commerce applications. E-Commerce or Electronics Commerce is a methodology of modern business, which addresses the requirements of business organizations. PGP and PEM are programs that allow a sender and a receiver to communicate in a way that does not allow third parties to read them and that certify that senders are really who they claim to be. As result, they are suitable for building virtually all kinds of online shops and e-commerce related (web) applications. These tools include software agents, distributed query generator, the distribution transaction generator and the declarative resource constraint base- which describes a business rules and environment information. The fact is that everyone is looking forward to have easy browsing on mobile than to go for getting an efficacious platform, which will surely help to grow user and customer’s attraction. E-commerce is an important element in the manufacturing industry such as MODENAS for them to participate in the worldwide markets globalization. E-commerce frameworks must be based on a strong architectural model. An e-mail user may send his/her message to either a store or forward Internet server or to an Internet server to which he/she has read, write and delete privileges. The OSI model consists of seven layers. Others define messaging as a framework for the total implementation of portable applications, divorcing from the architectural primitives of the system. To maintain the relationships that are critical to delivering superior customer value, management must pay close attention to service, both before and after sales. Designing the flowchart is a key point in any ecommerce website development. Software agents are mobile programs that have been called "healthy viruses", "digital butlers", and "intelligent agents".
