Since Terrific Airlines is promoted as a “…fast way out of town,” individual seats are not assigned, and flights of other carriers are not tracked. More specific notes about Terrific Airlines are listed below: Information about a route includes its unique number, its origin, its destination, and estimated departure and arrival times. To reduce costs, Terrific Airlines only has non-stop flights with a single origin and destination. Flights are scheduled for a route…

Annotated Bibliography As a graduate student, one of the fundamental techniques to gather research for a paper is the use of an Annotated Bibliography. Furthermore, as a human-computer interaction researcher, finding relevant literature to support a study is also part of preparing an analytical research paper. For this assignment, you’ve been assigned a topic (see below). You’ve also been assigned to a specific group (see Groups in Blackboard). Each member of the group is to find five UNIQUE references. These references are to be scholarly papers, not wiki, blog, or Website entries. Do not include textbooks or trade publications either. The use of Google Scholar is STRONGLY recommended. IMPORTANT: To support your research journey, read the Levy & Ellis (2006) article on how to maximize your research opportunities in Information Systems Research. (5 to 6) entries.

ER-Diagram and EER-DiagramHoliday Travel Vehicles (HTV) sells new recreational vehicles and travel trailers. When new vehicles arrive at the HTV, a new vehicle record is created. Included in the new vehicle record are vin-number, model, year, manufacturer, and base cost. Several manufacturers that supply the vehicle are Toyota, Chrysler and Ford. When a customer arrives at HTV, he or she works with a salesperson to negotiate a vehicle purchase. When a purchase has been agreed upon, a sales invoice is completed by the salesperson. The invoice summarizes the purchase with invoice no, date, vehicle vin-number, sale tax and final price. Customers are assigned a customer ID when they make their first purchase from HTV. Name, sex, DOB, address (street, city, zipcode), and phone number are recorded for the customer. Each invoice lists just one customer. A person does not become a customer until he or she purchases a vehicle. Overtime, a customer may purchase a number of vehicles from HTV.…

A company makes items. Each item has a name, ID and component quantity. Every item contains many components. Each component can be supplied by one or more suppliers. Suppliers have names and IDS. Each component has ID, name, description, suppliers who supply them, and items in which they are used. Not all suppliers provide components, and a component is not always associated with a supplier. Also, a component always have to be associated with one or more items. Finally, the company contact customers using their IDs, Names and Phones to sell them items. A customer can buy one or more items.

ENHANCE ENTITY RELATIOSHIP DIAGRAM The entity type PERSON has the following attributes: SSN, name, address (City/State/Zip), date of birth, age, and contact number. The entity also has the three subtypes: CAMPER, BIKER, AND RUNNER. Draw a separate diagram segment for each of the following situations:  1. At a given time, a person must be exactly one of three subtypes. 2. A person may or may not be one of these subtypes. However, a person who is one of these subtypes cannot at the same time be one of the other subtypes. 3. A person may or may not be the one of these subtypes. On the other hand,  a person may be any two (or even three) of these subtypes at the same time.  4. At a given time, a person must be at least one of these subtypes.

Make use-case diagram: The customer wants a system for bike racing registrations where Organizers of eventscan publish races, people who want to race can sign up and the system should also keeptrack of the old races to racers can "level up" and start in higher categories (cat).Racers who officially want to race need to sign up with the system with their name,credit card information. To be able to register for official races they need to buy alicence. The license is always valid for 1 year and has a specific ID and is for the racerscurrent level (cat). Racers are sorted into categories 5-1 where 5 is beginner and 1 isthe best category. Racers can only race in official events if they have the cat required,so they need to race against others their level.Organizers can create races. The interesting part is though that a race can consist ofdifferent stages. E.g. one stage is a road race, the other a criterium and the other atime trial (you can find what these are online). Each stage is on a…

Entity-Relationship Diagrams (ERD) Background Information: Study the following statements to determine the relationship between the entities • Each student has an academic advisor. An academic advisor can advise many students. • Each academic advisor has a specific parking spot assigned. • Each student can take up to five courses. and each course has up to 24 students. • Several adjunct faculty members share an office. Tasks: 1. Draw an ERD (it is just one diagram) showing the entities and the relationships among them. Include associative entities, if any. Also, remember to show cardinality (1:1, 1:M, M:N); you can use the cardinality notation or the crow’s foot notation. Remember that this is a graphical language, and you must follow the shapes of the elements in the diagram.
