Concept explainers

SQL

SQL stands for Structured Query Language, is a form of communication that uses queries structured in a specific format to store, manage & retrieve data from a relational database.

Queries

A query is a type of computer programming language that is used to retrieve data from a database. Databases are useful in a variety of ways. They enable the retrieval of records or parts of records, as well as the performance of various calculations prior to displaying the results. A search query is one type of query that many people perform several times per day. A search query is executed every time you use a search engine to find something. When you press the Enter key, the keywords are sent to the search engine, where they are processed by an algorithm that retrieves related results from the search index. Your query's results are displayed on a search engine results page, or SER.

Implement a new independent entity phone in the Sakila database. Attributes and relationships are shown in the following diagram: The diagram uses Sakila naming conventions. Follow the Sakila conventions for your table and column names: All lower case Underscore separator between root and suffix Foreign keys have the same name as referenced primary key Write CREATE TABLE and ALTER TABLE statements that: Implement the entity as a new phone table. Implement the has relationships as foreign keys in the Sakila customer, staff, and store tables. Remove the existing phone column from the Sakila address table. Step 2 requires adding a foreign key constraint to an existing table. Ex: ALTER TABLE customer ADD FOREIGN KEY (phone_id) REFERENCES phone(phone_id) ON DELETE SET NULL ON UPDATE CASCADE; Specify data types as follows: phone_id, phone_number, and country_code have data type INT. phone_type has date type VARCHAR(12) and contains strings like 'Home', 'Mobile', and 'Other'.

b) Consider the relational table PARTSUPP of the TPCHR sample database. Find SELECT statements that will use the index in the ways specified in the questions (i) to (iv) below. The values used to create the query such that the queries can meet the specified criteria is up to you, but the values must be sensible. i. ii. iii. iv. Execution of the first SELECT statement must traverse the index vertically then horizontally and it must not access the relational table PARTSUPP. Execution of the second SELECT statement must traverse the index vertically then horizontally and it must access the relational table PARTSUPP. Execution of the third SELECT statement must traverse the leaf level of the index horizontally and it must not access the relational table PARTSUPP.

What exactly does it imply to say that something is transitive? It is possible to convert tables that are in the second normal form to tables that are in the third normal form; however, the rule for doing so is not well known.
StayWell also rents out properties on a weekly basis to students attending summer school in the Seattle area. Design a database to meet the following requirements, using the shorthand representation and a diagram of your choice. For each student renter, list his or her number, first name, middle initial, last name, address, city, state, postal code, telephone number, and e-mail address. For each property, list the office number, property address, city, state, postal code, square footage, number of bedrooms, number of floors, maximum number of persons that can sleep in the unit, and the base weekly rate. For each rental agreement, list the renter number, first name, middle initial, last name, address, city, state, postal code, telephone number, start date of the rental, end date of the rental, and the weekly rental amount. The rental period is one or more weeks.
