Conversion of E-R diagram to relational schemaSchema is a correct translation of the E-R diagram submitted with appropriate tables, columns, primary keys, and foreign keys.
Using 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…

- Part 2: Relational data model. Take a subset of the ideas from the conceptual model you constructed in Part 1 and design a simple relationship model similar to the ones we discussed in Module 2, Video 4 Your model should have at least 5 tables You should include at least 20 attributes, or fields, in your model (20 total across all tables, not per table) Your model should be normalized Identify the primary key in each table, and state whether it is a natural or surrogate key For each relationship between tables, identify any foreign keys needed to define the relationship For each table, identify what type of system or systems you think the data might come from, like those we discussed in Module 1, Video 6.arrow_forwardConsider the given ER Diagram for Notown database in Figure 2. You have been tasked to recommend that Notown use a relational database system to store company data. Show the Structured Query Language (SQL) statements for creating relations corresponding to the entity sets and relationship sets in your design. Identify any constraints in the ER Diagram that you are unable to capture in the SQL statements and briefly explain why you could not express them.arrow_forwardTranslate the E-R diagram on page 1 (diagram) to database schema using MySQL Workbench (export as png or pdf). You can ignore the cardinalities on the ternary (Grant) relationship. Interpret the database schema on slide 4. Draw the E-R diagram underlying this schema. No need to draw the attributes.arrow_forward
- Transform the EER diagram to a set of relations and develop a relational schema.arrow_forwardModify the Er diagram given below and add 5 to 6 more additions to it such as entities attributes relationships etcarrow_forwardTranslate this ER diagram into a relational schema, Choose appropriate data types for each attribute and include primary key and NotNull constraints.arrow_forward
- Consider each of the takes and teaches relations as a fact table; they do not have an explicit measure attribute, but assume each table has a measure attribute reg_count whose value is always 1. What would the dimension attributes and dimension tables be in each case. Would the resultant schemas be star schemas or snowflake schemas?arrow_forwardConvert the ER diagram in the above question into relational model.arrow_forwardMap this ER diagram to a Relational Model and normalize it if needed.arrow_forward
- Use the technique of normalization to validate the structure of your relational schema. Demonstrate that each of your relations is in third normal form (3NF) by displaying the functional dependencies between attributes in each relation. Note, if any of your relations are not in 3NF, this may indicate that your ER model is structurally incorrect or that you have introduced errors in the process of deriving relations from your model.arrow_forwardAn ERD has m number of entities (strong, weak, parent, child all combined) and n number of relationship types (of all possible kinds). When transformed to the relational schema, Database designer come up with a solution which contained more than m+n relations. What could possibly be the reason? If you think the designer did a mistake then you can say that in your answer. Explain your answer if you think that will help. Answer:arrow_forwardPart II: For the given ER diagram, construct the relational schema by specifying the resulting relations, their attributes, keys, and foreign keys.
