viewed as a way of implementation and management of computerinformation systems. Information systems on the other hand are a

bit more challenging and complex in comparison to IT. Information

systems are a set of interrelated components responsible for

collecting, storing and distributing information that directly impacts

decision-making and control within an organization. Aninformation system helps employees analyze problems, helps create

new products, supports decision-making and control in anorganization, and also helps employees visualize complex subjects.

(Management Information Systems, 12/e- Pg 15-16)

InstructorExplanation:

Information technology (IT) consists of all the hardware and software that afirm needs to use to achieve its business objectives. Information systems aremore complex. An information system can be defined technically as a set ofinterrelated components that collect (or retrieve), process, store, anddistribute information to support decision making and control in anorganization. An information system:• supports decision making, coordination, and control• helps employees analyze problems• helps employees visualize complex subjects• helps create new products@ pp. 15 –16

7. Question : (TCO B)"Knowledge increases exponentially" is a phrase with which weare all familiar. How does this concept apply to electronic business andthe emergence of the digital firm? Support your contentions.

Student Answer: To put the quote into perspective, I think one way to interpret is to break down how the use of data affects knowledge/wisdom. Dataarranged in a certain manner leads to information, and information

leads to knowledge and knowledge leads to wisdom. As one

becomes wiser and more experienced, then it can be said that their

knowledge increases exponentially because of the continualdiscovery of new information. Everything we know today can be

tracked down practically in a chain/pyramid type of history. Today,

the internet enables us to feed our minds and expand our

knowledge; so much information is at our finger tips. And withthat, all human knowledge can be connected to anyone with access

to a computer. Businesses in turn take advantage of the humanknowledge to increase electronic business.

Instructor

Explanation:

Student answers will vary. A sample answer is: The exponential increases ofknowledge refer to shared information. For example, once the concept of awheel is established, inheritors of that knowledge do not have to reinvent thewheel. The Internet is a tool similar to the wheel: it is based on sharedstandards and universal tools. The Internet and shared networkingtechnologies are allowing new techniques for attracting customers andselling customers to be developed and adapted very quickly. For example,



although early Internet retailers had difficulty setting up secure credit cardtransactions and payment systems, today there are many systems in placeas vendors step in to create shared tools for doing this. The Internet isfostering shared knowledge and, as such, propagating ever greaterincreases in that knowledge.@ pp. 373 –405

8. Question : (TCO C) What types of relationships are possible in a relationaldatabase? Describe and give an example of each.

Student Answer: In a relational database, there are three basic operations used todevelop sets of useful data: select join and project. The select

operation creates a subset of records in the file that meet the

criteria. Select creates a subset of rows in a table to meet certain

criteria. The join operation combines relational tables to provide theuser with additional information that is not directly available in

individual tables. The project operation creates a subset consisting

of columns in a table. The columns would allow the user to create atable using only the required information. For example in a table,

one would need to extract information in columns that they need to

create the new table. (Management Information Systems, 12/e- Pg

215)Instructor

Explanation:

A one-to-one relationship occurs when each record in one table has only onerelated record in a second table. An example might be a table of salespeopleand a separate table of company cars. Each salesperson can only have onecar, or be related to the one car in the database. A one-to-many relationshipoccurs when a record in one table has many related records in a secondtable. An example might be a table of salespeople and clients. Each

salesperson may have several clients. A many-to-many relationship occurswhen records in one table have many related records in a second table, andthe records in the second table have many related records in the first table. An example might be a clients table and a products table. Clients may buymore than one product, and products are sold to more than one client.@ p. 221

9. Question : (TCO D) Describe the effect of cloud computing on traditional ITinfrastructure.

Student Answer: The biggest effect of cloud computing on traditional ITinfrastructure is that the user no longer needs to own their owninfrastructure. The fact that ownership of the infrastructure is not

needed, allows the user capital expenditure by renting usage of

infrastructure from a third party provider. By doing that, the useronly consumes resources as a service and pays for what he/she uses.

Based on that, the user can be billed monthly or quarterly based on

the amount of service used. With resources on the cloud, multiple



users can share computing power amongst themselves and alsoimprove utilization rates so services aren't left stagnant/idle. Cloud

computing in turn helps reduce and cut costs.

Instructor

Explanation:

Because websites, applications, and databases have been moved to a cloudvendor, the corporation does not need infrastructure, such as Web,application, and database servers, as part of its in-house computinginfrastructure. It is replaced by a network infrastructure that providesemployees with Internet access to the cloud services.@ Week 4 Lecture
