Suppose that you are given the following information for the articles publications: • Each article is published in a Journal only. Article may have their own identification number, name, and any other relevant information. • Articles cannot be duplicated and will be only accepted in a Journal. Journal will have their identification number, name, any other relevant information. • Authors may publish one or more articles at a time, but each article must be distinctive and published in the appropriate journal. • If necessary, the author may be required to present their work at a specific conference. The details of the conference must also be recorded. A reviewer will examine an article before it is published. Each reviewer is only allowed to review two articles from the same journal. Sketch an Enhanced Entity Relationship Diagram (Chen's Model) based on the scenario above. Include all the relevant entities and you are also encouraged to add any other relevant entities to specify the generalization/specialization/aggregation. Identify the PK and provide a sample of FK in the diagram.

Theoretical Computer Science

Usually, computer science seems like a practical field that involves studying, building, and working closely with computers. However, a subclass of this discipline also centers on the mathematical factors of the same. This is called theoretical computer science, and its focal point differentiates it from other branches of computer science: the rigorous mathematical approach it takes. This discipline falls under the umbrella of discrete mathematics, which is the study of countable or discontinuous mathematical structures.

Question

Suppose that you are given the following information for the articles publications:
• Each article is published in a Journal only. Article may have their own identification
number, name, and any other relevant information.
Articles cannot be duplicated and will be only accepted in a Journal. Journal will have
their identification number, name, any other relevant information.
• Authors may publish one or more articles at a time, but each article must be distinctive
and published in the appropriate journal.
If necessary, the author may be required to present their work at a specific conference.
The details of the conference must also be recorded.
A reviewer will examine an article before it is published. Each reviewer is only allowed
to review two articles from the same journal.
Sketch an Enhanced Entity Relationship Diagram (Chen's Model) based on the scenario above.
Include all the relevant entities and you are also encouraged to add any other relevant entities
to specify the generalization/specialization/aggregation. Identify the PK and provide a sample
of FK in the diagram.

ZCAS University is a large institution with several campuses. Each campus has a different name, address, distance to the city center and the only bus running to the campus. Each campus has one club. The name of the club, the building in which the club is located, the phone number of the club and the multiple sports which club offers, should all be recorded. The University consists of a number of faculties, such as the Art Faculty, the Science Faculty, and so on. Each faculty has a name, dean and building. A faculty may be divided into a number of schools, for example, the Science Faculty has a School of Physics and a School of Chemistry. Each school belongs to one faculty only and is located on just one campus, but one campus maybe the location of many schools. Every school has name and an building assigned to. Each school offers different programmes and each programme can be offered by only one school. Each programme has a unique code, title, level and duration. Each programme…
Question 7 You are given a list of courses that are currently available in BRACU that looks like the following: courses = ['CSE110','CSE111','MAT620','CSE520','EEE361','CSE650','MAT510]. All courses till 400 level (499) are for the undergraduate students whereas any courses above 500 are for the graduate or masters students. Write a python program that creates a dictionary from the above list where the keys will be each department name (CSE,EEE,MAT for the above example) and their values will be a dictionary of two keys - Undergraduate Courses and Graduate Courses.
B. Art Museum Database Draw an EER diagram to keep track of information for an art museum. Assume that the following requirements were collected: (10 marks) The museum has a collection of art objects. Each art object has a unique ID, a year (when it was created, if known), a title, and a description. Art objects must be categorized based on their type. There are three main types: painting, sculpture, plus another type called other to accommodate objects that do not fall into one of the two main types. A painting has a paint type (oil, watercolor, etc.), material on which it is drawn on (paper, canvas, wood, etc.), and style (modern, abstract, etc.). A sculpture has a material from which it was created (wood, stone, etc.), height, weight, and style. An art object in the other category has a type (print, photo, etc.) And style. The museum keeps track of artist information, if known: name, date born (if known), date died (if not living), country of origin, epoch, main style, and…

Database Design Before an Essential Oil product is marketed, testing is carried out based on the production batch from any essential oil. This is done to maintain the quality and content of the existing constituents in essential oils. Where the Test Percentage Content must reach the Minimum standard Percentage Content for each constituent. If there is one type of constituent that does not fulfill minimum standard, the batch will not be marketed because it does not meet the standard quality. 1. If recording the results of each testing process is still done manually,according to you please explain which approach fits between Centralized and View Integration for gathering requirements. 2.

Part Design a database for an Access Control System. The purpose of the system is to control who has access to which doors at what time. There are six entities in this database: ● ● Users Groups O A user can be assigned to more than one group. Doors AccessRules O Decides which Group has access to which Door at which TimeSchedule. Example: Group A can access the Front Door on Monday from 7am to 9pm. o o Example: Group B can access the Back Door on Saturday from 8am to 10pm. TimeSchedules To make it simple, we only need to pport Weekly Schedules. The TimeSchedules table has the following columns: Id O O DayOfWeek StartTime ■ EndTime o Example: a schedule with DayOfWeek-Monday, StartTime=7:00, EndTime=23:00 means this schedule grants access on Monday from 7am to 11pm. Entrance Logs O This table keeps a permanent record of which user accessed which door at what time. o The logs must remain valid even after the related records have been updated. For example, after user X is deleted, the…

Each company operates four departments, and each department belongs to one company. Each department in part (a) employs one or more employees, and each employee works for one department. Each of the employees in part (b) may or may not have one or more dependents and each dependent belongs to one employee. Each employee in part (c) may or may not have an employment history, which includes his employments until the employee joined this enterprise as well as the employment history within the enterprise (after joining). Which of the following statements are true about the ER diagram (assuming it is a good design)? Department will be a weak entity. Employee will be a strong entity.
