- StayWell also rents out properties on a weekly basis to students attending summer school in the Seattle area. Design a database to meet the following requirements, using the shorthand representation and a diagram of your choice. For each student renter, list his or her number, first name, middle initial, last name, address, city, state, postal code, telephone number, and e-mail address. For each property, list the office number, property address, city, state, postal code, square footage, number of bedrooms, number of floors, maximum number of persons that can sleep in the unit, and the base weekly rate. For each rental agreement, list the renter number, first name, middle initial, last name, address, city, state, postal code, telephone number, start date of the rental, end date of the rental, and the weekly rental amount. The rental period is one or more weeks.arrow_forwardPROJECT: 1) By using one arff dataset you should apply three different classification algorithm and you should compare the performances of those classification algorithms by using different parameters of the corresponding algorithms. While you are classifying the dataset use percentage split and k-fold cross validation to compare the results. You should explain all the attributes in detail and give brief information about the classifiers you are working with. Lastly use some items with unknown class labels and determine their classes with Weka. 2) Also apply the Apprior algorithm on another dataset that you choose. Explain all the rules and make some comments about the rules that you will find.arrow_forwardYou can only evaluate a model based on how well it performs on real-world data. what do you want to discuss in depth, expound on?

- Predictive modeling: Task: Ambulance Demand Data Generating Process: for New York City Dates of Coverage {Please identify the specific dates that will be used for this dataset in your modeling effort other than the City Health Department's Emergency Medical Services Division. } Frequency of data collection {how often is the data collected? After every incident? Daily? Yearly?} Agency / Organization collecting the data {who specifically is collecting the data? Please avoid using general references like “government” or “police} Original Unit of Analysis {What is the original unit of analysis for the data as provided? Calls for service? Census tracts? Cities?} Transformed Unit of Analysis{i.e. are you modifying the call data to support your model? Hint: if you are doing “demand” model you will be aggregating the data.} Data Generation Description{here, I want you in your own words to describe how you think the data was generated. Think 2-3 sentences.} Data…arrow_forwardusing the design file in the image attached to the question : Normalize the database in the design file Be aware of the possibility of duplicate data. Name in Role and Employee and Emp_Contact_name all refer to the same data. Name and Email in Vendor refer to the Vendor. Assumptions made: An employee works with one or more vendors. An employee may have none or many dependents. An employee may have many roles over the employee's work history and a record should be retained for each role.arrow_forwardJohn liked your work so much that he would like you to create a database for the comic book shop that you worked with in the first project.
