1 Read The Elder Research And Unilever Case Studies And Note The Types Of Informatio 2031987

/in /by

1. Read the Elder Research and Unilever case studies and note the types of information they were able to extract from the text data. (We don’t quite have that amount of information available, or quite that level of software, so your conclusions won’t be quite as detailed.)

a. Elder Research Inc. (2013). Improving customer retention and profitability for a regional provider of wireless services. Retrieved from http://datamininglab.com/images/case-studies/ERI_nTelos_Customer_Retention_Case_Study.pdf

b. Jiffy Lube Uses OdinText Software to Increase Revenue. http://odintext.com/wp-content/uploads/2015/10/odinText-Shell.pdf . There’s also an interesting interview video here: https://www.youtube.com/embed/2Zxmjir8Zwo?autoplay=1

c. These case studies are for inspiration only; there is nothing to turn in from them.

2. Choose a readily available text item which recurred over at least three time periods, spaced some distance apart. You want to make sure you have at least several hundred words of text (approximately one – two pages) for each time period, and you want something which will change noticeably over that time period. Some options could include:

a. The CEO’s letter to shareholders (I do Amazon.com below as an example – you may choose any other company) in three different years.

b. The State of the Union Address (or other political speeches) from three different Presidents, such as those from Woodrow Wilson, Lyndon B. Johnson, and Barack Obama

c. A writeup of something technical (like descriptions of Motor Trend’s Car of the Year and Finalists) from 1950, 1980, and 2010.

d. Some industry writeup (such as PC Magazine’s best new computers for 1979, 1989, and 1999).

3. Match your timeline to the subject. For political speeches, you will get the best results if they are at least 50 years apart. For faster-changing items (such as the cellular phone user’s manual), you can probably get away with things 10 years apart. You will have a much easier time making good graphs if you give yourself good raw data to work with.

4. Select your desired number of time periods. You must have at least three, and can use as many as you like. (i.e. 2000, 2005, and 2010 would be three time periods.)

5. Take your text items for each year and convert them into a text input file.

6. Run a Python program to determine the top X word count for each year. You will need to determine how many words you are going to use in your analysis; you should probably have somewhere between 5 and 30.

a. You will need to make decisions about stop words.

b. Make sure the bulk of your text processing is done in Python, not using the “search/replace” functions in Excel or Word. Part of this class’ skillset is exposure to Python, and this is how you should do it here.

7. Merge your Python word count data into an input file for Tableau. You may find it helpful to use Excel or some other tool for this.

8. Analyze your data. Emphasis here will be placed on visual analysis and text analysis.

9. As part of your analysis, take the top 3 interesting relevant words from your latest time period. (You can use some judgment here; for Amazon, “kindle” would be more interesting than “book” even if “book” had more occurrences.) Trace the trajectory of each of these 3 words over time – for example, at Amazon, the word “kindle” gains tremendously in popularity over time.

10. Create a managerial report outlining your findings.

A successful report will

· Contain a title page and a list of references and pass a plagiarism check in Turnitin

· Begin with a results-filled Executive Summary (half a page to one page)

· Be otherwise 5-10 pages in length (I will stop reading after page 10). So if you have 1 title page, 1 list of references, and 1 page of Executive Summary, you could turn in up to 13 pages of stuff.

· Contain reasonable typeface and margins (12-point Times New Roman with 1-inch margins work just fine).

· Show mastery of the readings in the class to date

· Showcase your data visualization skills in Tableau, with up to 5 graphs (I will not look at a sixth or further graph)

· Contain a list of your top 3 words, with your reasons for choosing them, and trace their trajectory over time

· Analyze anything else you find interesting

· Integrate your charts with your conclusions

· Give a busy executive a clear path to follow in terms of action items and a “to do” list

Please submit:

· All Python code you used (it’s OK if you simply used or modified the code I have here; just ensure the comments reflect your name and what you did.)

· All .txt text input files you used (I imagine you might have one input file for each year)

· All Excel (or other format) input files you used for Tableau, so I can see how your data shaped up

· Your managerial report (ensure the bibliographic reference include the source data; my report should include a reference to the Amazon.com shareholder letter). Name this file “XXXX-text-analysis” where XXXX is your name.

Good luck!

1 Question 1 Research On The Various Design Patterns Described In Smith 2015 And Gam 2819156

/in /by

1.Question 1

Research on the various design patterns described in Smith (2015) and Gamma et al (1999). Describe how software development productivity can be accomplished by the application of various Creational Design Patterns.

2.Question 2

Refer to the Software Solution Scenario described in Appendix A and also OO Software Design Patterns described in Gamma et al (1995) / Smith (2015 to answer the questions below:

You have been tasked to carry out the development of an online shopping system for iChipKart store. You are currently working on two use cases of the system: Checkout and Compute Price. An extract of the current analysis and design of these use cases are given in Appendix A.

Consider the two software design problems described below.

Design Problem 1 (Compute Price):

During the transition from Analysis to Design phase, you are designing the price computation for ease of incorporating different shipping and handling fees for different locations inthe pricing policies. In your design, you also want to ensure that various policies in pricing computation are encapsulated appropriately for ease of maintenance.

Suggested candidate design patterns (Proxy, Strategy, Template Method)

Design Problem 2 (Checkout):

During the transition from Analysis to Design phase, you are designing the functionality of free gifts for ease of offering and withdrawing the various gifts dynamically and for ease of modifying the price ranges of free gifts.

Suggested candidate design patterns (Chain of Responsibility, Composite, Iterator)

For each of these design problems, answer the following:

a. Choose one of the suggested candidate design patterns that you think best solves the problem. Justify the applicability of your choice. You need to research on various patterns and come up with your choices and justifications.

b. Applying scientific principles identify the participants for incorporating the chosen design pattern and modify the class diagram of the use case to show their relationships.

c. Critically analyze the patterns and list two benefits of incorporating the design pattern, with respect to the problem.

d. Concerns such as design of security properties and domain specific security is addressed while transiting from requirements engineering to design. Choose any two security design patterns of your choice and research their merits and demerits.Appraise you selected security patterns against the following pattern characteristics:

i. Level of Abstraction: Ease with which he pattern can be used in different contexts without redefinition.

ii. Completeness: The security speciation that is correct and complete.

iii. Reusability: The pattern should be easily applied and used in different contexts.

iv. Pattern Composability: The pattern should be easily used with other patterns.

v. Security Composability: The pattern can be used with other patterns without losing any of the security it provides, nor affecting the security provided by the other patterns.

vi. Valid-ability: The patterns’ security properties, as well as their implementation and usage, can be easily validated. This validation would preferably be automated.

3.What to submit:

Questions 1 and 2 and a written essay format. You may use the essay template given on Moodle.

4.Research References:

1) Erich Gamma, Richard Helm, Ralph Johnson, John Vlissides, Design Patterns : Elements of Reusable Object-Oriented Software,Addison Wesley, 1995.

Analysis and Design for Object Oriented Software
Online Shopping System for iChipKart

5.1Use Case Model Global View (Partial)

5.2Checkout Use Case

5.2.1 Brief Description

After a buyeradds items to the shopping cart, he/she will check out the purchased items. Items can be Books, Media (CD, hard disks, memory card etc.), TV, computing items and accessories like tablets, thumb drives etc. In order to make their business competitive,iChipKarthas decided to give its buyers one of the following memorabilia items as a free gift during the period 1 October to 15 January. The following describes the policy for these gifts:

(1) If the buyer purchases goods worth =$25 and iChipKart T-Shirt.

(2) If the buyer purchases goods worth =$50 and iChipKart backpack.

(3) If the buyer purchases goods worth =$100, he/she will receive aiChipKart portable hard disk of 1Tb.

Note thatiChipKartmemorabilia items are not for sale.

5.2.2 Flow of Events

This use case is invoked when the buyer chooses the Checkout option from the Purchase Screen.

i. The system invokes the Compute Price use case to compute the subtotal of items price of all purchased items (excluding the shipping, handling and other charges).

ii. The system determines the free gift that the buyer is eligible for this transaction, and adds (if eligible) the memorabilia to the shopping cart (this item is priced at $0.00).

iii. The system invokes Compute Price use case to compute the total price of this transaction, including the shipping, handling and other charges.

iv. The system presents the total price and prompts the buyer for payment details in Payment Screen.

v. Upon verification of the payment details, the system invokes the Print Receipt use case to print the receipt for this transaction.

vi. The system displays completion message.

vii. The buyer acknowledges the completion message and the system returns to the Purchase Screen.

viii. The use case terminates.

5.2.4 Sequence Diagram(Self research question, 10% bonus)

5.3Compute Price Use Case

Brief Description

This is an abstract use case which will be included in use cases such as Checkout. In this use case, thesubtotal of items andtotal price of the items in the shopping cart will be computed and other charges such as shipping and handling charges will be included as appropriate. The total price will constitute the following:

i.Base price of the items.

ii.Shipping charges.

iii.Handling charges (eg: fragile items will need to be specially packed, surcharge for oversized items, duties for dutiable items depending on country-specific policies, etc).

5.4Flow of Events

This abstract use case is invoked when other use cases want to compute the subtotal of items price of items in the shopping cart, or compute the total price of the items in the shopping cart including the shipping, handling and other charges.

i. The system traverses through the shopping cart items, determines the product price and computes the subtotal of items price of all the items.

ii.If shipping, handling and other charges are not required, the system returns the subtotal of itemsprice to the calling use case. Otherwise the system continues.

iii.Based on the shipping destination, the system computes the shipping charges and adds it to the total price.

iv.Based on the fragility of the items, the system computes the handling charges and adds it to the total price.

v.The system returns the total price to the calling use case.

vi.The use case terminates.
