  1. E-Commerce

Review Chapter 1 slide 1 -19

  1. What is E-Commerce?

A: The use of the internet and the Web to transact business. More formally, digitally enabled commercial transactions between and among organizations and individuals.

  1. What is E-business?

A: The digital enabling of transactions and processes within a firm, involving information systems under the control of the firm.

  1. What are the difference between E-Commerce and E-Business?
  • E-Commerce:
  • Transaction with customers
  • Involve transactions that cross firm boundaries.
  • E-Business:
  • Transaction with suppliers
  • Involves the application of digital technologies to business processes within the firm.
  1. Why do we study E-Commerce?
  2. To understand the differentiation of technology which more powerful than any of the other technologies we have seen in the past century.
  3. To understand the digital markets, fundamental, unprecedented shifts in commerce.
  4. To understand the Information Asymmetry (prices, costs, fees and profitable)
  5. Eight Unique Features of E-commerce Technology
  6. 1- Ubiquity: Available just about everywhere, at all times, making it possible to shop from your desktop, at home, at work, or even from your car.
  7. 2- Global reach: Permit commercial transactions to cross cultural and national boundaries far more conveniently and cost-effectively that is true in traditional commerce.
  8. 3- Universal standards:Shared by all nations around the world. In contrast, most traditional commerce technologies differ from one nation to the next.
  9. 4- Richness: Refers to the complexity and content of a message. It enables an online merchant to deliver marketing message with text, video, and audio to an audience of millions, in a way not possible with traditional commerce technologies such as radio, television, or magazines.
  10. 5- Interactivity: Allows for two-way communication between merchant and consumer and enabling the merchant to engage a consumer in ways similar to a face-to-face experience, but on a much more massive, global scale.
  11. 6- Information density: Is the total amount and quality of information available to all market participants. The internet reduces information collection, storage, processing, and communication cost while increasing the currency, accuracy and timeliness of information.
  12. 7- Personalization and Customization: Merchant can target their marketing messages to specific individuals by adjusting the message to a person’s name, interest, and past purchase. The result is a level of personalization and customization unthinkable with existing commerce technologies.
  13. 8- Social technology: Provides a many-to-many model of mass communications. Millions of users are able to generate content consumed by millions of other users. The result is the formation of social networks on a wide scale and the aggregation of large audiences on social network platforms.
  14. Major Types of E-commerce
  15. B2C: Business-to-Consumer: Online business selling to individual consumers. Ex: eBay is a general merchandiser that sells consumer products to retail consumers.
  16. B2B: Business-to-Business: Online business selling to other business. Ex: Food-trader is an independent third-party commodity exchange, auctions provider, and market information source that serves the food and agricultural industry.
  17. C2C: Consumer-to-Consumer: Consumer selling to other consumers. Ex: On a large number of Web auction sites such as eBay, and listing sites such as Craigslist, consumer can auction or sell goods directly to other consumers.
  18. P2P: Peer-to-Peer: Use of peer-to-peer technology, which enables internet users to share files and computer resources directly without having to go through a central Web server, in E-commerce. Ex: Bit-Torrent is a software application that permits consumers to share video and other high bandwidth content with one other directly, without the intervention of a market maker
  19. M-commerce: Mobile commerce: Use of wireless digital devices to enable transactions on the Web. Ex. Wireless mobile devices such as PDAs (Personal Digital Assistants) and cell phones can be used to conduct commercial transactions.

- Integrity: Ensures that information displayed on a Web site or sent or received via the Internet has not been altered in any way by an unauthorized party.

- Non-repudiation: Ensure that e-commerce participants do not deny (repudiate) their online actions.

- Authenticity: Verifies an individual’s or business’s identity.

- Confidentiality: Determines whether information shared online, such as through e-mail communication or an order process, can be viewed by anyone other than the intended recipient.

- Privacy: Deals with the use of information shared during an online transaction consumers want to limit the extent to which their personal information can be divulged to other organizations, while, merchants want to protect such information from falling into the wrong hand.

- Availability: Determines whether a Web site is accessible and operational at any given moment.

  1. How technology helps protect the security of messages sent over the Internet?
  2. Encryption is the process of transforming plain text or data into cipher text that cannot be read by anyone other than the sender and the receiver. Encryption can provide four of the six key dimensions of e-commerce security.
  1. GIS
  2. What is GIS?
  3. is defined as an information system that is used to input, store, retrieve, manipulate, analyze and output geographically referenced data or geospatial data, in order to support decision making for planning and management of land use, natural resources, environment, transportation, urban facilities, and other administrative records.
  1. What is a coordinate system?
  2. a reference system consisting of a set of points, lines, and/or surfaces, and a set of rules, used to define the positions of points in space in either two or three dimensions.
  3. How many Types of coordinate systems are there?
  4. There are two types of coordinate systems: geographic coordinate system and projected coordinate system.
  5. What do a global or spherical coordinate system such as latitude-longitude often referred to?
  6. Referred to asgeographic coordinate systems.
  7. What is Geographic Coordinate System (GCS)?
  8. Is acoordinate systemthat enables every location on the Earth to be specified by a set of numbers. The coordinates are often chosen such that one of the numbers representvertical position, and twoor threeof the numbers representhorizontal position. A common choice of coordinates islatitude,longitudeand elevation
  9. Draw Meridians Lines of Longitude and set a line of the Equator?
  10. Draw Parallels Line of Latitude and set a line of the Equator?
  11. How does measure Longitude angle?
  12. Each line of longitude runs north–south and measures the number of degrees east or west of the prime meridian. Values range from -180 to +180°. How does measure Latitude angle?
  13. Lines of latitude run east–west and measure the number of degrees north or south of the equator. Values range from +90° at the North Pole to -90° at the South Pole.Draw Map projections using Cartesian coordinate system? (uses two axes)
  14. Where is the Cambodia location stand in the world with GCS system?

  16. What is prime meridian and central meridian?
  17. The Prime Meridian is the meridian (line of longitude) at which the longitude is defined to be 0°.
  18. Central Meridian is an imaginary straight line joining the north and south poles of a planet's disk as seen from Earth.
  19. What is unit in the earth, and how many hours are there for each span of a UTM zone?
  20. UTM project. 24 hour are there for each span of a UTM zone
  21. Each spanning of UTM zone has 6 degrees wide of longitude. How many time zones are there in the earth, and how many hours are there for each span of a UTM zone?
  22. Describe the main parameters of GCS and UTM projection?
  • Parameters of UTM projection are: Datum, Units, Origin Long, Origin Lat, Scale Factor,

False Easting, False Northing.

  1. Draw the spheroid Everest relates to spheroid WGS84?
  2. Why the Cambodian and some Asian are using UTM projection?
  3. Because in the world using mile so Cambodia or some Asian countries use local UTM zones based on the official geographic coordinate systems in use.
  4. What is the Universal Transfers Mercator?
  5. Is geographic coordinate system uses a 2-dimensional Cartesian coordinate system to give locations on the surface of the Earth. It is a horizontal position representation, i.e. it is used to identify locations on the earth independently of vertical position, but differs from the traditional method of latitude and longitude in several respects.
  6. The UTM system is not a single map projection. The system instead divides the Earth into sixty zones, each a six-degree band of longitude, and uses a secant transverse Mercator projection in each zone.
  7. What is Datum, Projection, GCS, Annotation/Text, Point/Node, Vertex, Layer, Arc, Line, Polyline, and Polygon?
  8. Datum:The reference specifications of a measurement system, usually a system of coordinate positions on a surface (a horizontal datum) or heights above or below a surface (a vertical datum).
  9. Projection:
  10. GCS:A three-dimensional, earth-centered reference system in which locations are identified by their x-, y-, and z-values.
  11. Annotation/Text:In ArcGIS, text or graphics that can be individually selected, positioned, and modified.
  12. Point/Node:A geometric element defined by a pair of x,y coordinates and In a geodatabase, the point representing the beginning or ending point of an edge, topologically linked to all the edges that meet there.
  13. Vertex:One of a set of ordered x,y coordinate pairs that defines the shape of a line or polygon feature.
  14. Layer: a slice or stratum of the geographic reality in a particular area, and is more or less equivalent to a legend item on a paper map.
  15. Arc: On a map, a shape defined by a connected series of unique x,y coordinate pairs. An arc may be straight or curved. A coverage feature class that represents lines and polygon boundaries. One line feature can contain many arcs. Arcs are topologically linked to nodes and to polygons.
  16. Line: On a map, a shape defined by a connected series of unique x,y coordinate pairs. A line may be straight.
  17. What is the geodatabase?
  18. Is a collection of geographic datasets of various types used in ArcGIS and managed in either a file folder or a relational database. It is the native data source for ArcGIS and is used for editing and data automation in ArcGIS.
  19. There are three types foGeodatabase: File Geodatabase, Personal Geodatabase, and ArcSDEGeodatabase. Describe of each type?
  20. File Geodatabase: Stored in a file folder. Up to 1 TB per dataset. Any platform. Supports a single editor and a few readers. No versioning support.
  21. Personal Geodatabase: Stored in Access. 2 GB size limit, but effective size is 250 to 500 MB per geodatabase. Windows only. Supports a single editor and a few readers. No versioning support.
  22. ArcSDEGeodatabase:Stored in a RDBMS (Oracle, SQL Server, DB2, Informix). Supports many editors and many readers. Uses ArcSDE. Provides versioning and multiuser support.
  23. A key geodatabase concept is the dataset. It is the primary mechanism used to organize and use geographic information in ArcGIS. The geodatabase contains three primary dataset types: Tables, Feature classes, Raster datasets. Describe of each type?
  24. Tables: provide descriptive information for features, rasters, and traditional attribute tables in the geodatabase
  25. Feature classes:are homogeneous collections of common features, each having the same spatial representation, such as points, lines, or polygons, and a common set of attribute columns, for example, a line feature class for representing road centerlines. The four most commonly used feature classes in the geodatabase are points, lines, polygons, and annotation
  26. Raster datasets: represent geographic features by dividing the world into discrete square or rectangular cells laid out in a grid and are commonly used for representing and managing imagery, digital elevation models, and numerous other phenomena. Often rasters are used as a way to represent point, line, and polygon features.
  27. Why does geodatabase need feature dataset?
  • Because feature dataset is a collection of related feature classes that share a common coordinate system. It is used to organize spatially related feature classes into a common dataset:
