- Please provide a list and illustrative example for the three forms of binary relationships that are not covered in this book. Draw a regular E-R diagram as well as an IE Crow's Foot E-R diagram for each of the three cases studied here.arrow_forwardModify the Er diagram given below and add 5 to 6 more additions to it such as entities attributes relationships etcarrow_forwardUsing the relations ATTACHED, normalize your relations into first, second, and third normal forms. First, KINDLY describe the changes required to your relations to meet the standard of the first 1NF and then 2NF and lastly 3NF. Then, you should provide an Entity Relationship diagram that is in 3NF. All attributes, entities, keys, and relationships should be included and labelled. Hint: Remember that in the hospital software system, the “Patient” relation includes the “medicines” attribute and the “Appointment” relation includes the “allergies” attribute. Allergies describe a list of any known allergies and medicines describe a list of medicines prescribed for a patient. Please add: Define or describe the changes required to get the relations into the 1st normal form. Define or describe the changes required to get the relations into the 2nd normal form. Include an Entity Relationship diagram in the 3rd normal form. The primary and foreign keys, at a minimum, are defined for each…arrow_forward
- In your group, you will need to create an entity relation (E-R) diagram using the Crow's foot symbols that models the problem. This will include: Summarise the ERM's components, and names the entities and their relationship (As given in the Textbook, p.143, Table 4.4) all entities, relationships (including names) and attributes that are relevant, primary keys identified, and include relationship participation - participation (optional / mandatory) symbols and cardinality. The E-R diagram should be completed using the standards of this unit. Use Microsoft Visio to create the E-R diagram.arrow_forwardPlease include the eer diagramarrow_forwardConsider the following E/R diagram with isa relationships, noting that attribute b is the key of R. If we use an E/R-style approach and convert this diagram into relations, which of the following relations will be among the result? Select one: Y(a,c,d) T(a,b,d) Z(b,c) S X(a,b,c,d) R barrow_forward
- Draw an Entity Relationship diagram for modeling the following system. Use relational modelling techniques in your design. You are free to make reasonable assumptions for your model unless they conflict with the definition below. Also explain your design with a paragraph. [Caution: Create your solution using paper and pen. Then put the image of your solution here. Drawing/writing with computer tools will not be accepted. Also include your name and signature in the solution paper]Problem definition: “There is a need to keep track of data for a hospital. The hospital building consists of several departments. Each department is identified with its name. For each department, the following data should also be stored: the number of floors, opening hour, and closing hour. Each department has a number of rooms. Each room is identified by its room number, but there might be rooms with the same name in different departments. At each department, many doctors and nurses can work.A doctor is…arrow_forwardIt is a "Database Design" Subject. Please answer the following question. An arc is a constraint about two or more relationships of an entity. Create a description of an arc using an example. [Hint: you are required to draw an Entity Relationship Diagram and write descriptions based on the example use].arrow_forwardb) An ER/EER diagram modeling your database (use appropriate symbols, and don’t forgetassociative entities where appropriate). This will be based on the business rules you created, somake sure you’ve written clear rules! (30 points)• Feel free to use an appropriate design tool you would like for your ER diagram (e.g.http://draw.io), or do it by hand and scan it in; just make sure it is legible and that itfollows the notation/style taught in class. Do NOT use other styles, such as “Visio”notation that includes PK/FK.c) A list of normalized relations (using the notation from class) that is based on your ER diagram.Be sure to include foreign keys, etc. (30 points)arrow_forward
