CIS test 3

-Available just about everywhere, at all times

• -starting to dominate advertising
• -2 way communication between edv and customer-social network 1)inexpensively target a large audience 2) behavior targeting-track clicks for understanding interest

• Technology works through interaction with the user.
• -creating an engaging environment for the consumer

-the complexity and content of a message

-the effort required to find suitable products

The technology reduces information costs and raises quality

when one party in a transaction has more information that is important for the transaction than the other party (and gives them advantage

higher (as compared to digital markets)

The removal of organizations or business process layers responsible for the intermediary steps in a value chain

saves users money and time by processing online sales transaction and generating a fee each

provides a digital environment where buyers and sellers can meet, search for products, display products, and establish prices for those products

actively helped in solving some business problems by getting help from the "crowds" ex: netflix

business-to-consumer: electronic commerce involves sales of goods and services among business

-tracking the click-streams of individuals on thousands of Web sites for the purpose of understanding their interests and intentions and exposing them to advertisements which are uniquely suited to their behavior

electronic data interchange:enables the computer to computer exchange between two organizations of standard transactions such as invoices, bills of lading, shipment schedules, or purchase orders.

-involves not only purchasing goods and materials but also sourcing, negotiating, with suppliers, paying for goods, and making delivery arrangements

Mobile commerce: the use of handheld wireless devices for purchasing goods and services from any location

-a Web site offering content or services charges a subscription fee for access to some or all of its offerings on an ongoing basis

goods that are directly involved in the production process

• Consumer-to-consumer:
• electronic commerce involves consumers selling directly to consumers (e-bay)

• SDLC oldest
• method for building info system. Phased approach to building a system
• -1) systems analysis 2) system design 3) hw/ sw acquisition 4) testing 5) training
• and documentation 6) conversion 7) production and maintenance.

• -identify problem, gather information, devise alternative solutions, and make a decision about the best solution
• -develops a detailed description of what a new IS needs to perform

• -identify who needs what information, where, when, and how
• -what users need should drive system building effort

how the chosen solution should be realized

means by which a user and system interact with each other

detailed testing of individual computer programs

tests the performance of the information system as a whole

provides the final certification that the system is ready to be used in a production setting

both the old system and its potential replacement are run together for a time until everyone is assured that the new one functions correctly

replaces the old system entirely with the new system on an appointed day, carrying the risk that there is no system to fall back on if problems arise

changes in hardware, software, documentation, or procedures to a production system to correct errors, meet new requirements, or improve processing efficiency

specifically you are testing and documenting formed, formed rapidly

allows endusers, with little or no formal assistance from technical specialists, to create simple information systems, reducing the time and steps required to produce a finished application

establishing standards for project requirements

Rapid application development: the process of creating workable systems in a very short period of time

offers a logical graphic model of information flow, partitioning a system into modules that show manageable levels of detail

building an experimental system rapidly and inexpensively for end users to evaluate

Object-oriented modeling is based on the concepts; objects belonging to a certain class or general categories of similar objects have the features of that class. Classes of objects in turn inherit all the structure and behaviors of a more general class

groups of objects have been assembled into software components for common functions, such as a graphical user interface or online ordering capability, and these can be combined to create large-scale business applications

build small objects that do a routine task, and assemble small objects to create a new system

the application of knowledge, skills, tools, and techniques to achieve specific targets with specified budget and time constraints

help you evaluate alternative systems, inventories all them for a firm

shows how specific information systems fit into a company's overall business plan and business strategy

classifying knowledge

the decision maker must provide judgment evaluation, and insight to solve the problem

repetitive and routine, a definite procedure for handling them

• -Intelligence-discovering, identifying, and understanding the problems occurring in the organization
• -Design-identifying and exploring various solutions to the problem
• -Choice-choosing among solution alternatives
• -Implementation-making the chosen alternative work and continued to monitor how well the solution is working

• primarily hard-copy reports
• -fixed regularly scheduled reports based on data extracted from your TPS

(decisionsupport system ) provide analytical models or tools for analyzing large quantities of data and supportive interactive queries for middle managers who face semi structured decision situations.

a database of data used for query and analysis; a software system with models, data mining, and other analytical tools; and a user interface

used to forecast sales

ask what-if questions repeatedly to determine the impact on outcomes of changes in one or more factors

Backward sensitivity analysis helps-if I want to make $1 mil, how much must I produce

Geographic information systems: a special category for DSS that use data visualization technology to analyze and display data for planning and decision making in the form of digitized maps

used for solving complex, poorly understood problems for which large amounts of data have been collected

used for finding the optimal solution for a problem by examining a very large number of alternative solutions for a prob: represents a solution as a string of 0s and 1s

provides tools for the management, delivery, tracking, and assessment of various types of employee learning training

generating realistic-looking 3D graphic designs that can be rotated

interactive graphics software to create computer-generated simulations that are so close to reality that users almost believe they are participating in a real-world situation

• structured: explicit knowledge that exists in formal documents, as well as in formal rules
• -in order to search for a retrieve objects, they have to be classified
• -semistructured: incorporate repositories of documents, reports, presentations, and best practices, e-mails

expert systems model human knowledge as a set of rules

Customer decision-support system: support the decision making process of an existing or potential customer
