- You have been asked to design and implement a database for CTU, which includes 3 entities (tables), as follows: Students Faculty Courses Part 1 Create a Word document that includes the following: Identify at least 3 attributes for each entity, including the following: Student's entity should have an attribute for the program the student is enrolled in. Faculty should have an attribute identifying their rank. Properly identify all of the primary keys (use solid underlines). Create an entity relationship diagram (ERD) from the entities. You may use SmartDraw, Visio, Erwin, or even Word to draw the diagram. Take a screenshot (no need if you use Word), and insert it into the Word document. Part 2 Use Microsoft Access to implement the database that you designed in Part 1, and include the following: Create the Student, Faculty, and Course tables in Access. Add a few instances in each table. Create 2 queries for the following objectives: Find the student names for all students who are in the…arrow_forwardWhat makes entity relationship (ER) diagrams so important for database design, in your opinion?arrow_forwardDevelop an Entity Relationships Diagram (ERD) based on the relational schemas in the 3NF for the starting relational schema in un-normalized form presented below.

- create a table for the class entity in an ER diagram of a school system. Show the composite key in class table. Fill the table with 4 records. At what level in the database architecture we create tables ?arrow_forwardIt is essential to discuss the various database table possibilities when dealing with subtype associations.Decide on a format, and then talk on the issues that should be addressed in it.arrow_forwardSwing Jazz Club ERD Problem Follow the Simple Procedure for ERD diagramming to design an ERD using the following user provided information. Remember the ERD will eventually turn into the design for a database from a top down view. Make sure you resolve any many to many conflicts. Label an identifier or primary key and all pertinent attributes given. If an attribute is not readily apparent from the user information, then make one up that makes sense for the particular entity. Therefore, all entities should end up with at least an identifier and another attribute that makes sense. You may use any of the approaches shown by the book, though the ER-Model and Crow’s foot are the most common. Make sure you show entities, relationships, cardinality, and optionality. Swing Jazz Club The Swing Jazz Club teaches swing and jazz dancing and offers both private and group lessons.
