Information system Question 2: Suppose you have the following scenario: People who use the Palm Tree System are either farmers or experts. They both have name and phone number. The farmer has address and has the ability to search and buy a product, reserve an appointment and add comments. An expert has a number of years of experience and can answer questions and post advices. An Expert can communicate with many farmers while a farmer can communicated by only one expert. By using Star UML tool, draw a Class diagram for this scenario.

Information system Question 1: Suppose you have the following scenario: The Palm Tree System is a system that offers multiple services to farmers. The farmer can search for product, buy product and reserve appointment for consultation. Also, he can add comments on the services provided for him. An expert can answer questions and post advices. Both of them need to log in to the system. By using Star UML tool, draw a Use Case diagram for the above scenario.
Write a response to the following question using standard argument format: (Premises, therefore, conclusion) 1. Based on what you have learned in this module and in your own understanding, explain what a network is. Include how networks are used and why they might be important in our society.(This will serve as the intro to your argument and establish a common point) 2. What are the advantages and disadvantages of a network?(This will serve as your premise portion) 3. Do the dangers outweigh the benefits (or vice versa)? Why or why not?(This is your conclusion statement that must be supported by your premises)
Your vision of email. Is there a specific path that an email takes as it travels from sender to receiver? Make a tally of everything of interest that you have discovered. How are they different from one another, and what motivated that differentiation? Let's assume there is a wide range in the complexity of the models.

When do you plan to start using email, and how soon do you anticipate starting? A linear path is followed by an email, starting with the sender and finishing with the receiver of the message. Your results should be documented in great detail. Are there any possible explanations for the differences, and if so, what are they? Imagine a varied collection of models, each of which presents its own unique set of difficulties (or abstractions).
How important is email in your future plans? The journey of an email starts with the sender and concludes with the receiver. It's important to write down anything you find out. Is there a difference in meaning, and if so, why? Suppose there is a wide range of models, each with its own unique level of complexity (or abstraction).
1)Modeling: Make a CDM from the following scenario: * A retail company wants to manage their sales activity. We have the following information- The date of sale, with the possibility of rolling up to the week, month, quarter and year- the store where the sale was made: store name, brand, address, city, department and region. - The employee associated with each sale: surname, first name, date of birth, social security number. Each employee is associated with a store.the customer who purchased the product surname, first name, date of birth, address. The product sold product name, d - iption, category, unit price. The order: quantity sold, amount of turnover, amount of margin. A transaction can consist of one or more orders. The indicators (quantity, turnover, margin) can be negative if it is a reimbursement. 2) In your MCD above, what are the dimension tables? * 3)In your MCD above, what are the fact tables?
2. Read the following paragraph and answer Q1 =============================================================== Situation: Puppy Palace works with TV and movie producers who need dogs that can perform special tricks, such as headstands, somersaults, ladder climbs, and various dog-and-pony tricks. Puppy Palace has about 16 dogs and a list of 50 tricks from which to choose. Each dog can perform one or more tricks, and many tricks can be performed by more than one dog. When a dog learns a new trick, the trainer assigns a skill level. Some customers insist on using dogs that score a 10, which is the highest skill level. =============================================================== Q1) If “Trick” is an attribute of Dog, what kind of problem may occur in the logical design phase? Choose the most proper one. a) redundancy b) dependency c) multi-value
Suppose you are organizing a conference where researchers present articles they have written. Researchers who want to present an article send a paper to the conference organizers. The conference organizers have access to a committee of reviewers who are each willing to read up articles each. Each paper submission gets reviewed by up to reviewers. Moreover, each submission has a particular topic and each reviewer has a specialization for a set of topics, so papers on a given topic only get reviewed by those reviewers who are experts on that topic. The conference organizers need to decide which reviewers will review each article (or equivalently, which articles will be reviewed by which reviewers). Explain how they could use a flow network to solve this problem.
Telemedicine is the ability to provide medical assistance from a distance using telecommunication. For this example, imagine that a platoon of soldiers might be out in the battlefield. While a medic might be with them, he/she cannot constantly monitor each soldier’s vital signs, but if various sensors were sewn into soldier uniforms, vital statistics could be monitored from a distance by a doctor at headquarters. That doctor may be able to identify a medical problem for one of the soldiers and relay that information and instructions for care back to a medic in the area. The doctor at headquarters should be able to select a given soldier and see that soldier’s vital signs on a portable computer device (e.g., iPad). Perhaps the medic in the field might even have a video camera so that the doctor may be able to view a wound. Design the interface that the HQ doctor would see. Using the display design principles design an interface mockup using graphics, photos, and/or text to show what…
Which mental picture of an e-mail do you have? The path of an email starts and finishes in the same location. Make a note of your results. To begin, why are differences necessary? Have you noticed how the amount of model detail (or abstraction) varies?
In what ways do you foresee the use of electronic mail? What physical steps are required for an email to get from one recipient to another? Make a tally of everything you have discovered. How and why were these divides set up amongst them? Assuming that the degrees of complexity contained in the different models vary substantially (or abstraction) (or abstraction).
