Chapter 3, Problem 3.9RQ
Program Plan Intro
SQL:
- SQL stands for “Structured Query Language”.
- The current version of SQL is “ANSI SQL – 92”.
- SQL is not a
programming language. It is text-based and it is also called as data sublanguage.- In order to get SQL as a complete programming language, it should be included in scripting languages like Java, C#, and so on.
- It contains constructs which are used to define and process
database . They are executed using DBMS-supplied command prompt. - Some of the DBMS products provide GUI tools in order to perform tasks are as follows:
- SQL Server
- Oracle Database
- MySQL
Table Creation:
Creating table comes under Data Definition Language (DDL). Syntax for creating table is as follows:
CREATE TABLE TABLE_NAME (
Column1 datatype,
Column2 datatype,
…
);

- What is a "referential integrity constraint"? Give examples to show its uses.arrow_forwardtrue /false The system-defined database used as a template for all “to be created” databases is the tempdb database. The entire contents of this database, including database options, are copied to the new database. Thus, if you modify this database, all databases created afterward will inherit those changes. OUTER JOIN types return only non-matching tuples. When we create a primary key (PK) some Database Management Systems (DBMS) automaticallly create a Foreign Key constraint on the attributes of the PK. SQL Server DBMS is one of these DBMSs. If a relation has more than one candidate key, we can implement this by creating a Primary Key constraint for one of the candidate keys, and a UNIQUE constraint for each and every one of the alternate keys. Using the Query Editor Window, “select TOP 1000 Rows” retrieves the first 1000 tuples of a relation (assuming that the relation has 1000 or more tuples). If there is…arrow_forwardWhat is the distinction between the two kinds of integrity constraints?arrow_forward
- Give a normalized version of the Index_metadata relation, and explain why using the normalized version would result in worse performance.arrow_forwardWhat are the differences between the two types of integrity constraints?arrow_forwardThink about the foreign-key constraint on the instructor's department name property. Please provide examples of additions and deletions that could go against the foreign-key restriction.arrow_forward
- "Referential integrity constraint" is a term used to describe this. Using real-world examples, demonstrate the use of the concept.arrow_forwardCreate a website for collecting information during a vaccination camp conducted in an organization for COVID-19 using Node JS and Mongo DB. For each person in the vaccination camp collect, the employee id, name, department, government issued unique id. If the person is a dependent of the employee, record that information also. All the above details are stored in the database along with the date and time. During the course of the camp, the committee members from the organization may ask for the total count of employees' vaccinated, total count of dependents vaccinated. They may also ask to display the details of the employees vaccinated so far.arrow_forwardDefine the term Referential integrity constraint?arrow_forward
- Not all versions of this database include referential integrity constraints for all foreign keys. Use whatever commands are available for the RDBMS you are using, investigate if any referential integrity constraints are missing. Write any missing constraints and, if possible, add them to the associated table definitions.arrow_forwardThe WorkOrders table contains a foreign key, ClientNum, which must match the primary key of the Client table. What type of update to the WorkOrders table would violate referential integrity? If deletes do not cascade, what type of update to the Client table would violate referential integrity? If deletes do cascade, what would happen when a client was deleted?arrow_forwardImplement 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!arrow_forward
