Given the database schema below, write a relational algebra expression to get the count of records in the DEPENDENT relation group by Essn. Also, show the result of your query.
Indicate the changes (using the shorthand representation) that you would need to make to the original KimTay Pet Supplies database design to support the following requirements. There is no relationship between customers and sales reps. When a customer places an order, any sales rep can process the order and create the invoice. On the invoice, you need to identify both the customer placing the order and the sales rep responsible for the invoice. Draw an E-R diagram for the new design.
The database used for this question is a very simple one with the following schema: (Primary keys are bold, foreign keys are underlined) CUSTOMER (CustID, FirstName, LastName, City, Phone, Email) INVOICE (InvoiceNumber, CustID, Date) INVOICE_ITEM(InvoiceNumber, ItemNumber, Quantity) ITEM (ItemNumber, ItemName, UnitPrice) When a customer makes a purchase, an invoice is created. The invoice may be for many items. For example, in a single purchase, a customer might buy 10 Back Scratchers, 4 Hair Removers and a Dog Lead. Provide relational algebra (NOT SQL) queries to find the following information. NOTE: You can use the symbols s, P, etc., or the words’ PROJECT’, ‘RESTRICT’ etc. as you prefer. You do not need to try to make efficient queries – just correct ones. Where you use a join, always show the join condition. List the dates on which Homer Griffin made purchases. List the first and last names of customers who have bought “Back Scratcher” or “Hair Remover” List the first…
E-R diagrams or DBDL may show database structure. Why do you prefer this method?
When constructing a database, the designer must know what types of relationships exist between records in different data sets, such as one- to-many or many-to-many. Give three examples for each of these relationships.
By adding a time characteristic, a relation may be turned into a temporal relation, but will the functional linkages be preserved? How is this issue addressed in a database that tracks time periods?
Question A city college would like to maintain their academic information in a MySql database system. The following are the interested information: Courses: Catalog # (M170 for instance) Credit Hours; Name of the Course (Database Design Fundamentals for instance) Course Descriptions Prerequisite Components (Lecture, or Laboratory for instance) Classes: Class # Class Name (usually the course name, M 170 for instance) Start Date End Date Meeting time (9:30 am ~ 12:15 pm, for instance) Days in a week (Monday) Term (Spring 2018, for instance) Location (TIE Building for instance) Room (UB 301, for instance) Instructor Online status (online, or in-person) Faculty: Employee Id (001880301, for instance) First Name Last Name Title (professor, for instance) Email Phone Office Location (TIE building, for instance) Room (UB303, for instance) Student: Student ID First Name Last Name Plan Sub Plan Advisor Current GPA Grade of each course The Term you got the grade for a course.

Swing 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. Swing Jazz charges $60 dollars per hour for a private lesson and $10 dollars per hour for a group lesson.…
How do you determine the level of normalization required for a particular database design?
Database design diagrams (DBDL) and entity-relationship (E-R) diagrams (ER) are both valid ways to depict a database's structure. For what reasons do you choose one tactic over another?
For the purpose of illustrating the structure of a database, either an E-R diagram or DBDL may be used. If that's the case, which strategy do you favor, and why?
In the definition of a relational database, explain what is meant by "normalized relations" ?
