Swing Jazz Club ERD Problem Follow the Simple Procedure for ERD diagramming to design an ERD using the following user provided information. Remember the ERD will eventually turn into the design for a database from a top down view. Make sure you resolve any many to many conflicts. Label an identifier or primary key and all pertinent attributes given. If an attribute is not readily apparent from the user information, then make one up that makes sense for the particular entity. Therefore, all entities should end up with at least an identifier and another attribute that makes sense. You may use any of the approaches shown by the book, though the ER-Model and Crow’s foot are the most common. Make sure you show entities, relationships, cardinality, and optionality.

Please written by computer source Part I - Modeling You are building a database for a comic book store customer management system. Given the database specification below, your job is to turn the specification into an ER diagram. Your notation must be consistent with the notation used in our lecture notes. You can use all constructs and notations discussed in our lecture notes and nothing else (i.e.. oven notations used in the textbooks but not in our lectures cannot be used). Your ER diagram should capture all the information and constraints in the specification but, at the same time, be minimal. It means that redundant entities, relationships, attributes and constraints should be avoided. You may use any drawing tool of your choice (for example, Dia, diagrams.net, Lucidchart, etc.) to draw your ER diagram. Hand drawings will not be accepted. Database Specification The database keeps information about comic books, customers, orders, inventory and reviews. First, the database should…

The data requirements are summarized as follows: o The mail order company has employees, each identified by a unique employee number, first and last name, and Zip Code. o Each customer of the company is identified by a unique customer num, first and last name, and Zip Code. o Each part is identified by a unique part number, a part name, price, and quantity. o Each order placed by a customer is taken by an employee and is given a unique order number. Each order contains specified quantities of one or more parts. Each order has a date of receipt as well as an expected ship date. The actual ship date is also recorded.
Prepare an entity-relationship diagram for the database in a following company: Holiday Travel Vehicles sells new recreational vehicles and travel trailers. When new vehicle arrives at Holiday Travel Vehicles, a new vehicle record is created. Included in a new vehicle record are a vehicle serial number, name, model, year, manufacturer, and base cost. When a customer arrives at Holiday Travel Vehicles, he or she works with a salesperson to negotiate a vehicle purchase.

1. Draw an E/R diagram for a University database. This database should contain information about the university's students, departments, professors, teaching assistants (also students of the university), courses offered by a department, which students are enrolled in what courses, which professors are teaching which courses, student letter grades. You may include any other information deemed appropriate. • Some restrictions apply as listed below| 1. A Professor only works in at most one department. 2. Students and professors have been assigned unique email id's 3. A course is only taught by one professor and offered by one department. 4. A course is uniquely identified by the course number, section number and semester. Example: CSCE520-001 Spring21 5. A course has at most one TA.
