Based on: Entity-Relationship Diagram with the following requirements: There are Professors (ie users) with the changeable attributes Professor_Name, Field, College, PhD_Date There are Flubs (ie posts) with the unchangeable attributes Content, Purpose, Moment, Inventor (which is the creating Professor) There are Bounces (ie shares) where a Professor can share another Professor's Flub Add ID attributes as necessary Content of Flubs only needs to be a text of fixed length Professors can have/be Colleagues (ie friends/followers) A Flub can get Citations (ie likes) by other Professors Create the SQL for a single View called "Flubbergasting" of a Professor which includes all attributes from Entity-Relationship Diagram, as well as how many Flubs, the average number of Bounces the Flubs had, and total Citations across all Flubs by that professor.
Can you please create an ER diagram model for the Open Kattis System website. For the ER diagram, you need to model the data that would be needed to recreate all of the web pages that are displayed to ordinary contest observers or participants on OpenKattis. You do not need to model any additional data that is revealed only when you set up a contest, or create a new problem. Also can you explain the solution, thanks!!
Create an Entity/Relationship (ER) diagram to model the following scenario: An online magazine maintains a list that ranks restaurants based on reviews sent by the magazine's subscribers each restaurant is uniquely identified by an auto-generated code other attributes associated with a restaurant include its name, address, price range (1-3), rating (1-5 stars), and cuisine type there are many cuisine types and more can be added in the future subscribers are uniquely identified by their email and each have a name subscribers can review as many restaurants as they want, and a restaurant can be reviewed by many subscribers a review has a rating (1-5 stars), a date, and comments the system does not allow more than one review on the same date to the same restaurant and written by the same subscriber new reviews entered do not become immediately available as the magazine needs to check if the comments are appropriate and do not contain cursing or anything nasty/offensive once a new review…

Need a Rule set, architecture design and access control matrix for below: RBAC Ruleset: So 1 subjects/owner 1) users (subjects), 2) files (objects), 3) roles, ===can be 4 roles user 4) operations. Roles are abstractions like “researcher,” “analyst,” “system_operator,” or “employee.” Operations are abstract tasks like “reporting,” “analysis,” “compiling” or “view”. Here’s a quick partial example: Jerry assigned NOVA_researcher NOVA_researcher does NOVA_reporting NOVA_reporting can rw NOVA/reports/*.txt
Draw an ER diagram for the following scenario- • An instructor has an ID, a name, and a phone number. An instructor teaches a course • A course has a code, course name, credits, and an instructor. Each course uses a textbook. • A textbook has ISBN, name, publisher, editor, and authors. Your ER diagram should have entities, attributes, composite attribute, multivalued attribute, key attributes, binary relationships, and a total participation. Explain your rationale behind each design choice. Please draw the ER diagram on paper showing all seperate parts for each instructor, course and textbook. Showing each connection seperately and explaining which connection is which

Draw an ERD for the following situation. Artwork is generated by an artist, denoted as 0:1 (0 for an unknown artist). An alternative approach could involve having a valid artist instance with the name "Unknown." This modification would allow the enforcement of a business rule stating that every artwork piece must be associated with an artist stored in the database. Consequently, the cardinality near the artist entity in the diagram would change to a mandatory 1. The Item Status attribute of artwork enables the categorization of artwork as Display (requiring a valid value for the Item Museum Location attribute), Storage, Loan, or Shows. Artwork items can be featured in a show; however, the current entity-relationship diagram (ERD) does not provide a mechanism to indicate that an artwork item cannot be part of two shows with overlapping dates. This business constraint will need to be documented as part of the system design.
create an Entity Relationship Diagram using the following Entities and their respective attritubes for an online programming competition registration for both leaners and university students. 1. Host it's attributes (host Id, hostFirstName,hostLastName, hostTelNum,hostEmail,hostPassword) 2. Student(StudentId, StudentfirstName, Student Email, StudentPassword, InstitutionName) 3. Learners(leaner Id, leanerFirstName, leanerLastName, leanerPassword, SchoolName) 4. Competition(compId, comName, compDate,comTime, compRules, compRequirements) 5.

Let's break down the information into entities, attributes, and relationships: Entities: 1. Ship - ShipID (Primary Key) - ShipName - ShipType 2. Captain - CaptainID (Primary Key) - CaptainName - CaptainLicense 3. ShipmentTrip - TripID (Primary Key) - DeparturePort - ArrivalPort - RouteDetails 4. ShipmentManifest - ManifestID (Primary Key) - Date - GoodsList 5. Goods - GoodsID (Primary Key) - GoodsName - GoodsType (BM or LM) 6. Port - PortID (Primary Key) - Street - City - State - PostalCode - Country Relationships: - Ship to ShipmentTrip (Many-to-Many): - Ship can participate in multiple ShipmentTrips, and a ShipmentTrip can involve multiple Ships. Create a junction table `Ship_ShipmentTrip` with attributes `ShipID` and `TripID`. - Captain to ShipmentTrip (Many-to-Many): - A Captain can be assigned to multiple ShipmentTrips, and a ShipmentTrip can have multiple Captains. Create a junction table `Captain_ShipmentTrip` with attributes `CaptainID` and `TripID`. - Captain to Ship…
