Draw an ER Diagram for the Activity - Centers in Cyprus. Use following specifications and clearly indicate the unique identifiers and show all cardinalities (minimum and maximum numbers). For an activity-center you need to keep the following information. Unique center_no, center_name, address (composed of post code, street and city) and a phone_ number. A member can be registered in at least 1 activity - center. For each member keep unique member_number, member_name, date of birth, age, address (only the city and house number is important) and phone numbers (mobile and home). In an activity - center there can be zero or many members. One of the members can be the leader of an activity -center. An activity-center can be located in one and only one city, but in a city there can be at least zero and at most 5 activity-centers. For each city you need to keep unique city_ code and a city name.

A college course may have one or more scheduled sections or may not have a scheduled section. Attributes of COURSE include Course ID, Course Name, and Units. Attributes of SECTION include Section Number and Semester ID. Semester ID is composed of two parts: Semester and Year. Section Number is an integer (such as 1 or 2) that distinguishes one section from another for the same course but does not uniquely identify a section. How did you model SECTION? Why did you choose this way versus alternative ways to model SECTION?

Each publisher has a unique name; a mailing address and telephone number are also kept on eachpublisher. A publisher publishes one or more books; a book is published by exactly one publisher.

When using subtype associations, talk about the database table choices that are accessible.Decide the design you want to employ and talk about the relevant issues.
You are to design a Hospital database. So before creating the database, your task is to draw the ER diagram based on the following data collected and analyzed: A hospital will have a name, unique id, multiple helpline numbers (one for doctor's appointment, one for ambulance, one for bill information and one for other services' info) and locations. A hospital may have more than one location as it may have different branches and each of the locations will have a building no., street address, road no. and city name. A patient will have a name, unique ID, may have more than one phone number, age, height, weight and symptoms. A patient takes an appointment in a hospital and the appointment date is recorded. A patient may have an attendant. An attendant will have his/her name, contact numbers and relationship with the patient as a record in the database. Due to the covid situation, the hospital authorities will only allow 1 attendant with 1 patient.
The various database table choices should be discussed when dealing with subtype associations.Discuss the issues that are relevant to the layout you decide to utilize.
