There are 2 questions to answer around 150-200 words
Q1)
Both error events and escalation events are used for exception handling in BPMN 2.0 workflows, but they signal different situations and have different effects on the process flow.
Explain the concept for each one and the effects on the process flow.
Q2)
In Process-Oriented Enterprise, values are characterized by some determinants for example:
Time Flexibility
Responsiveness Quality Price In your own words, define each one of them and briefly explain why these values are considered determinates?

There is two separate task Task 1 : This comprehensive project requires to design an enterprise architecture using ArchiMate.l already start the project and I want you to add a new stakeholder layer using archimate . The details will be in the PDF file Task 2 : You are required to create a creative illustration that summarizes the content of Unit 4: Views and Viewpoints.

Consider a network with multiple routers interconnected to form a complex topology. Describe how you would optimize the routing protocols in such a network to minimize convergence time and maximize network efficiency.

Write a one-page summary of the paper “Human Mate Choice is a Complex System Download Human Mate Choice is a Complex System” comparing it to “The matching hypothesis reexamined. 
Your summary should include the following sections:
1. The Problem: What is the question or problem the authors are trying to address in relation to “The matching hypothesis reexamined”?  What is the motivation behind developing a more complex model and comparing to the original matching hypothesis model?  In your own words, write a paragraph that addresses each of these questions. This is the introduction to your review.
2. Agent-Based Simulation: What new modeling features are in this model? You don’t have to describe the complete model but what are main new ideas incorporated into this model?
3. Main Results: How did each modification change the outcomes? Because there are a number of results, focus what you believe are the most important results.
4. Discussion: After reading this paper, what do you think about the results of “The matching hypothesis reexamined”? What does “Human Mate Choice is a Complex System” demonstrate about agent-based modeling more broadly?
Review must be in your own words (you should paraphrase the paper, not quote from it). The whole review should be about a page single spaced, with about a paragraph for each section. Carefully proof read your review so that it reads well and upload it.

AuctionBase
In this assignment, we are developing an online e-commerce website (similar to eBay). You are implementing a version of AuctionBase (which is based on an assignment from the University of Wisconsin).
User registers to the website (using a username, email, name, address, and phone number. ) Each user is identified by a unique id.
A user can be a buyer or a seller (or both).
Auction runs only on a single item.
A seller places items for Auction.
The item is identified by an ID and has a name and may belong to multiple categories, a location (which may be different from the seller location), and descriptions.
For each category, we keep track of its id, name, and description.
Auctions would have a start time, end time, and a starting asking price.
A buyer can bid on items, the bid with the highest bid win the auction.
A buyer may review the seller (a rating from 1 to 5) and write feedback.
The seller specifies the shipping options that may include pickup, each shipping option has a price and time.
The seller provides her bank information (bank name, routing number, and account no).
The system stores the payment information for credit card information (card number, expiration date, CCV code, name, and billing address).
The winner bidder specifies her choice of shipping method and has to pay for the price of bid and shipping cost.
The status of the buyer payment is recorded, upon the successful payment, the seller must ship the order within two business days.
The tracking information (of shipment) is recorded, if applicable. The buyer confirms the delivery of the item. The payment is released to the seller after delivery is confirmed.
Each bid must be higher than the previous one.
For each auction, we store the number of bids and the last price (this information is stored for performance).
To simulate the execution of the system, we create a table for the current time.
This table should at all times contain a single row (i.e., a single value) representing the current time of your AuctionBase system.
Constraints for Users
No two users can share the same User ID.
All sellers and bidders must already exist as users.
The bidder must have a valid credit card.
Constraints for Items
No two items can share the same Item ID.
Every bid must correspond to an actual item.
An item cannot belong to a particular category more than once.
The end time for an auction must always be after its start time.
The Current Price of an item must always match the Amount of the most recent bid for that item.
Constraints for Bidding
A user may not bid on an item he or she is also selling.
No auction may have two bids at the exact same time.
No auction may have a bid before its start time or after its end time.
No user can make a bid of the same amount to the same item more than once.
In every auction, the Number of Bids attribute corresponds to the actual number of bids for that particular item.
Any new bid for a particular item must have a higher amount than any of the previous bids for that particular item.
Constraints for Time
All new bids must be placed at the time which matches the current time of your AuctionBase system.
The current time of your AuctionBase system can only advance forward in time, not backward in time.
Deliverable
Design EERD schema for the system.
Create the Relation model in SQL
Design your constraints: Create a file called constraints.txt in this file, you will specify, in plain English, how you implemented each of the 16 constraints in your database schema, if possible.
Implement your constraints. (Trigger or otherwise).

When you are trying to convince someone why your position is valid, having research to back up your claim can strengthen your point and convince them.In this unit, you learned about analyzing data. In your programs, you used rather small data sets. Real-world research often studies massive quantities of data, often referred to as “big data.” Can you think of reasons why having large quantities of data is important? In this project, you will research a big data application.
Objectives
Write a scientific report modeling a written research paper on big data applications.
Your Task
Think of an area that interests you: sports, arts, entertainment, international relief efforts, government, careers, or the weather. 
Think of a question you would like to answer. Is it better to wait until the battery is low before you recharge your smartphone? How does a streaming service like Netflix or Hulu decide which shows to offer? 
Look for a website where someone already collected a large quantity of data to answer that question. While commercial big data sets may have tens of thousands of values, for this project, look for a data set with at least 100 values.  
You are not going to write a program to analyze these data because you have not yet covered how to read data files. You can describe how the researcher(s) who collected the data used them to answer your question.
Your Document Requirements
Part 1: Name
Your name
Part 2: Title
Part 3: Question(s) to Answer
A paragraph that introduces your topic and the question(s) to be answered
Part 4: Exposition
Describe the data you found, including a link to the page
Explain the answer to your question(s)
Give credit to your sources, whether using direct quotes or not
Part 5: Conclusion
A paragraph summarizing your analysis
Part 6: Bibliography
What to Turn In
Turn in your project file. Before you do, compare your work to the rubric.
You can use this rubric.
This is a sample. It is a guide to the layout of a sample project. Since topics may vary, it is just a guideline.

In Project 12, we want to make use of UX Design principles to analyze a website of your choice (don’t forget to include the URL).  This will be in the form of a report or paper.  You should thoroughly and carefully go through the website and all of its options, links, content, forms and form elements, graphic design, and layouts to analyze its functionality (or lack of it) and user experience.  What works?  What does not work?  What can be improved?  What is necessary?  What is not necessary?  What can be simplified?  In what ways does the content or design help the functionality?  In what ways does it interfere with the functionality?  Be sure to consider the perspective of the user in your analysis.
– Be as specific as possible in your analysis and recommendations.
– Use of annotated screen shots is not required, but would be very helpful.
– Recommendations for improvements will weigh heavily in the grade.
While there is no specific length requirement for this assignment, a thorough analysis would probably take at least 3-5 pages.
