During the past weeks, you have been introduced to software development planning techniques and tools. You have actually gained some experience using a few design techniques and tools in planning to create an application that meets business requirements. A design document was the resultant outcome of your efforts. You have also coded a couple object-oriented programs that meet these planned-for requirements. These tasks have given you a sense of what is required to plan for and to develop applications.

In this assignment, you should consider all that you have learned thus far in planning activities, and consider how architectures might aid in software development.

Prepare a 3-5 page Word document that answers the following questions:

• What does software architecture provide?
• What exactly is the role of the software architect and how does this individual work with the development team?
• Do you believe that architectural design is important? Support your statements.
• Identify and describe architectural drivers.

Assignment Description

You are the lead trainer for the software development team at a large telecommunications company. You have been tasked with preparing a training document that explains the principles of polymorphism, inheritance, and encapsulation. Research these principles and provide examples for each principle, showing how they would be used in software development. Be sure to answer the question of how each principle would be employed in the software development process.

Java programmers use class hierarchies for the purposes of inheritance. For example, given a Tree class, you could define Conifer and Deciduous subclasses that inherit from the parent Tree class, as follows:

In your training document explanations regarding inheritance, depict inheritance by using a computer memory hierarchy in a class hierarchy diagram.

Deliverable

Prepare a 6-8-page document that provides detailed explanations for polymorphism, inheritance, and encapsulation. Research computer memory hierarchy and the topic to use in your inheritance explanations at this link, making sure to cite it in APA style if you use specific information from the article. Develop a class hierarchy diagram for the memory hierarchy found at the URL. Include in your class hierarchy diagram at least three subclass levels. Each class and subclass must include at least one variable and one method.

Please submit your assignment.

For assistance with your assignment, please use your text, Web resources, and all course materials.

• For this assignment, submit a 500+ word write-up responding to the following question: A terrorist threat has been made via phone against the water system. The caller stated that he would be releasing Tularemia into the water system in the next 4-6 hours. We are not certain of where this action may take place, but we must protect the citizens of our city. Your task is to identify what we can do to counter this biological attack. There is a very SIMPLE answer to this question, and it can even be found in the paper, Water and Terrorism , which discusses the acts of terrorism that are capable of being carried out against our various water systems.
• Your assignment will be graded according to the essay rubric, which can be viewed when accessing the assignment link.
• Resources:
• Maps, Schematics, and Source Material are provided below: (The usage of the files starting with Zenith City will be discussed during the online session.)
  • Security Vulnerability Self Assessment Guide for Small Drinking Water Systems Serving Populations between 3,300 and 10,000
    • This Security Vulnerability Self-Assessment Guide is designed to help small water systems determine possible vulnerable components and identify security measures that should be considered in order to protect the system and the customers it serves. A “vulnerability assessment” (VA) is the identification of weaknesses in water system security, focusing on defined threats that could compromise its ability to meet its various service missions – such as providing adequate drinking water, water for firefighting, and/or water for various commercial and industrial purposes.

Write a program that reads two input files (both comma separated files) and creates a nested dictionary
object with users (as keys in the outer dictionary) and their movie ratings (as values to the outer dictionary
key; but these are dictionary objects themselves with movies as keys and ratings as values).

First, from the file that contains the people names and their geographical locations, simply read each
person’s name present in the first column and discard the rest. As you read the names, create the keys for
a dictionary object. The second file containing movie ratings shows each person who rated a movie along
with their rating. (Keep in mind that the rating field should actually be stored as a numeric value since
perhaps in the future we may want to do some arithmetic operation with it). Each line of data in the
second file becomes a key value pair of the outer dictionary object whose keys are the people name

Assignment Description

This assignment is to develop your first object-oriented program. You will utilize classes, common data types, and control structures. Following are the instructions.

Step 1: Define a Computer class that can be used to describe your computer. The class must have at least two attributes. One variable must be an integer data type and the other must be a String data type. At least one method should be defined in your class. Step 1a: Prepare a class diagram to illustrate your Computer class. Copy to a Word document. Step 1b: Prepare the source code that implements your Computer class. Give your source code a filename of Computer.java.

Step 2: Prepare a program that utilizes your Computer class. The requirements for the program include prompting the user for input, making a calculation, and printing out the results. Begin by creating your pseudocode for this program. Once you have your pseudocode, copy it into your Word document. You can now begin writing your program.

Your program should prompt the user for information about their existing computer followed by information about a future, more desirable computer. This means that your program will create two instances of Computer class, the first instance reflects the existing Computer, and the second instance reflects the future Computer.

Use the Scanner class for obtaining input from the user keyboard. The program must calculate the difference (improvement) between the existing and future Computer class variables of integer data type. For example, Computer class may contain an integer variable named memory. The value of the memory variable for the existing Computer instance may be 8, while the value for this variable in the future Computer instance may be 10. Calculating the difference would indicate an improvement of 2.

Print to the screen the values for the existing computer class and the desired computer class, along with the calculated improvement.

Your assignment submittal should include your properly commented Java source code for your Computer class as well as for your program.

The first step should be to plan your program. Prepare a Word document that shows your program plan description including class diagram and your pseudocode defining program logic.

The second step should be to write the code based upon your planning document.

Submit the Word design document, source code for Computer class and for your program. Include both .class files.

Please submit your assignment.

This homework asks you to rebuild the album editor for Tk. The GUI (graphical user interface) will allow a user to click an album to update. The user can change the album title and year. Another button allows creating new albums.

Your code does not need to use pickle to open/save the album data; just make a simple starting list of a couple albums (a list of dictionaries, as before).

Refer to this video and the Tkinter book.

The behavior should be as follows:

• Use a list of dictionaries to keep track of the album data.
• When the program starts, there should be at least two albums already in the list. The list should only show album titles.
• After the user clicks an album title in the list, they can click “Get Album”, which causes the album title and year to appear in the respective text boxes.
• If the user updates the album title or year in the text boxes, the user can then click “Save Album”, which causes the text boxes to clear and the list to reflect the new album data.
• If the user clicks “New Album” (regardless of whether an album is selected), the text boxes are cleared and a new item is shown on the list with the title “(No Title)”.

Dream Builders, New York, has approached you to develop a software application that will automate the management of the vehicle parking system at their new shopping mall, Zing. Following is the problem statement in the words of Mr. David Wong, project manager, Zing, Dream Builders.

“We are building a marvelous piece of architecture, which is a huge recreation and shopping complex. We are expecting hundreds of customers every day and managing parking is surely going to be a big problem. We have enough space to park hundreds of vehicles but I am aiming at something different, a computerized parking management system.”

What we want from you is a product that can help us automate the parking system. I do not know much of the technical jargon but I can tell you how I see it. Suppose I am an attendant at the entrance to the mall and a vehicle drives in, then all I should have to do is ask the driver his or her name and enter the name and the vehicle number into the computer. Then, using the software you develop, I should be able to look for a vacant location in the parking. I should then ask the driver to pay, and give him or her a slip specifying the location in which he or she has to park the vehicle.

Such a system will help us in various ways. For example, it will be easier for us to manage large number of vehicles, utilize maximum space available, and reduce manpower Moreover; our customers will surely be more satisfied because it will save them the trouble of searching for a vacant location to park. I am ready to invest a generous amount on this product but what I am looking at is a very innovative product.”

Based on the above scenario and your understanding, create a 2- to 3-page document in Microsoft Word, that includes answers to the following questions:

• What questions do you need to ask to get better understanding for this project?
• What kind of requirement gathering techniques will you use to collect the full list of requirements in addition to what is listed above? Ensure that you pick at least two techniques.
• How would you deal with the possibility of requirements change?
• Using any drawing tool, create the following models for the autopark project:
  • Use case model
  • DFD
  • Software requirements specification document

Support your responses with examples.

Cite any sources in APA format.
