5.3 Consider a large, industry-specific product such as a hospital management system for a group of hospitals. Discuss the pros and cons of using Agile methodologies versus a traditional process where more rigid planning and documentation are required. Focus on issues such as project size, team size, continuing multiple releases over the years, expanding the product for an international market, and worldwide customer support.

6.4 In collecting requirements for an employee information system, the employee is a major entity. What are some of the attributes of this entity that you would consider asking as part of the requirements? Express the entity and attribute in an entity-attribute table. Add an additional column to the table and express the data characteristics for each of the attributes.

Examples include (but are not limited to):

Australia, Brazil, China, Costa Rica, Egypt, France, Germany, India, Japan, Mexico, Morocco, Saudi Arabia, Sweden, Switzerland, Turkey, United Kingdom, Venezuela

Step 2 (25 pts):

Research the following areas of business etiquette for this country:

Introduction of Country to include: time zone differences, monetary exchange rate, typical family income, dominant language(s), major products, educational system, industry and business trends (increases and decreases).
Normal hours of business operations and any other typical or non-typical work day practices like scheduling meetings, etc.
Current job market statistics.
Educational backgrounds of professionals.
At least one other custom or business practice observed and important to know.

Step 3, Unit 7 Professionalism (25 pts):

Business dress for men and women.
Important points about holding a conversation with them.
Addressing persons properly. (titles, etc)
Successful business dining and etiquette in public and in home of business counterparts.
Non-verbal communication and behavior that is acceptable and unacceptable.

Step 4, Unit 8 (30 pts):

Wrap up the conversation about the country you researched by answering the following questions. Post your discussion in the main discussion board.

How do cultural differences affect the work place?
If you are working in a business in Northeastern Wisconsin how could you be affected by global diversity?
Specifically, as an IT professional working in the area of your AAS Degree, consider how your job would affect the company’s success in the global business arena. (i.e. Networking students…what kinds of things would the IT infrastructure need to have in place to be able to conduct business with a location outside of the US? )

For each of the following recurrences, use the “master theorem” and give the solution using big-Θ notation. Explain your reasoning. If the “master theorem” does not apply to a recurrence, show your reasoning, but you need not give a solution.

Limit method

Questions:

  1. [8 marks] Prove the following two identities using the limit method. Recall that lgn =log2 n.

(i) [4 marks] n/lgn = o(n/lglgn).

(ii) [4 marks] √nlgn = o(n/lgn).

Give sufficient details in your solutions. For example, to show lim = 0, give the steps of applying l’Hopital’s Rule.

  1. [12 marks] For each of the following recurrences, use the “master theorem” and give the solution using big-Θ notation. Explain your reasoning. If the “master theorem” does not apply to a recurrence, show your reasoning, but you need not give a solution.

You are required to use the version of the master theorem taught in class (also posted in the online notes), which is the same as the master theorem in the 4th edition of the textbook. Do NOT use the master theorem in the third edition of the textbook, which covers fewer cases.

(a) T(n) = 8T(n/2) + n2

(b) T(n) = 16T(n/2) + (n/lgn)4

(c) T(n) = 8T(n/3) + Θ(n2)

(d) T(n) = 3T(⌈n/3⌉) + nlgn

  1. [10 marks] A problem database people are often interested in is the following: Consider a set of hotels of acceptable ratings. For each hotel, we know how far away it is from the beach and how much a room costs a night. Ideally, we want to book a room in the cheapest hotel that is closest to the beach, but probably such a hotel will be impossible to find. Therefore, we are willing to compromise. Whether we are willing to trade distance from the beach for price depends very much on our personal preferences, but we would like to avoid booking in a hotel A if there exists a hotel B that is both cheaper and closer to the beach than hotel A.

For a hotel H, let dH be its distance from the beach and dH its price. Then, according to the discussion above, we consider a hotel A a candidate for booking a room if there is no hotel B that satisfies the following conditions:

(a) dB ≤ dA,

(b) pB ≤ pA, and

(c) at least one of these two inequalities is strict.

Given a set S of n hotels, your goal in this assignment is to develop an algorithm that finds all the candidate hotels in O(nlgn) time using divide-and-conquer, listed in increasing distance to the beach. You are not allowed to using any sorting algorithms in your solution.

You can make the following assumptions about the input and the output:

Input: An array S[1..n] of pairs of integers (d,p), in which S[i].d stores the distance of hotel i to the beach and S[i].p stores the price of hotel i. Note that two hotels may have the same distances and/or prices.

2Output: An array C of pairs of integers such that its elements C[1],C[2],… give the distances and prices of all the candidate hotels, listed from the candidate hotel closest to the beach to the one farthest away from the beach.

Important: In all of the assignments of this course, when you are asked to give an algorithm for a problem, you are (unless otherwise indicated) expected to

(i) describe the idea behind your algorithm in English;

(ii) provide pseudocode;

(iii) argue that your algorithm is correct; and

(iv) analyze its running time.. Since these requirements apply to all the assignments in this course, this reminder will not be repeated for future assignment questions

Memory Characteristics

Determine the memory structure used in your computer architecture.
You may choose to have a unified memory for both data and instructions or you may prefer a separate memory for each.
Determine the size of your proposed memory.
Determine what instructions can access the memory and how.
In the previous milestone, you determined all the instructions that can be handled in the proposed computer architecture. In this milestone, determine what instructions can access the memory and how.
Determine the cache levels.
You may choose to have one or more cache levels. In each cache level, you have to determine if this level is a unified or a separate cache for both data and instructions. In addition, you have to select the cache size for each level.
Determine how cache works.
Determine how to locate a block in the cache, and how to choose a block to be replaced from the cache.

What happens if data is stored in more than one place in a database? What if someone changes the information in one place and not the other—how do you know which information is correct?

CMIS 320 Project 4

Objectives
• This lesson covers the following objectives:
−Define the purpose of normalization in database models
−Define the rule of First Normal Form in the normalization process
−Determine if an entity conforms to the rule of First Normal Form
−Convert an entity to First Normal Form if needed

Purpose
• Think about storing your friends’ phone numbers in three different places:
−your address book, your cell phone, and a sheet of paper that you have taped to your refrigerator
• It’s a lot of work if a friend changes his/her phone number
• You have to change it in your address book, cell phone, and the sheet of paper taped to your refrigerator

Purpose
• What happens if data is stored in more than one place in a database?
• What if someone changes the information in one place and not the other—how do you know which information is correct?
• Redundancy like this causes unnecessary problems in a database

Purpose
• Normalization is a process that is used to eliminate these kinds of problems
• One of your goals as a database designer is to “store information in one place and in the best possible place“
• If you follow the rules of normalization, you will achieve this goal
