Consider the below given statements: 1. Referential integrity constraints are always specified between two entities in a schema. 2. Referential integrity constraints are always specified between entities having recursive relation. Which of the above statements is incorrect?
Create a version of the hybrid merge-join method that is suitable for situations where both relations are not physically sorted but have a sorted secondary index on the attributes to be merged.
Consider the following relations for a simple airport databas Hangars (hangNo, capacity, location, status) AirplaneTypes (Model, capacity, weight) Airplanes (regNo, model, hangNO) Owners (owner, name, address, phone, ssn) Owns (regNo, ownID, startedDate) There are four foreign keys for this database: 1. The attribute hangNo of the relation Airplanes that references the relation Hangars, 2. The attribute model of the relation Airplanes that references the relation AirplaneTypes, 3. The attribute regNo of the relation Owns that references the relation Airplanes, and 4. The attribute ownID of the relation Owns that references the relation Owner. Q1: Write SQL statements to define the above relation Hangars. You should choose a suitable data type and/or daya size for each column and be sure to declare appropriate integrity constraint(s). Q2. Which of the following SQL statements is used to define the above relation Airplanes? Ensure the data type and size for each attribute are…
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.…
Implement your table design by creating table statements. Your tables should have constraints such as primary keys and foreign keys. (You can use MySQL Workbench or any other database management system of your choosing). Types such as Char, Integer must be correctly placed. 2) Add one trigger to your database that utilizes a default function of your DBMS 3) Add dummy data to your database. (5 manual entries for each table should be sufficient.) 4) Consider the nominal forms and integrity of your database, it will affect your grade. Export your database from your DBMS, zip it and submit the zip file. Thank you!
Create a version of the hybrid merge-join method that is appropriate for the situation in which both relations are not physically sorted, but both have a sorted secondary index on the attributes that are being joined.
"The sole purpose for having relations is to record instances of functional dependencies," the author says in the passage. What does this imply, in your own words?
Explain the role of functional dependencies and candidate keys in normalization.
