Intermediate SQL Concepts

A query is a request for data or information from one or more database tables. This information could be presented in the form of pictorials, graphs, or complicated findings which helps in easy interpretation. Structured Query Language (SQL) is the most widely used programming language for retrieving and organizing data from relational databases. Collection of tables with rows and columns is referred to as a database. SQL is the language of databases. It makes it easier to extract specific data from databases, which can then be used for analysis.

Indexed sequential file. Consider the relation named "student" which is mapped to a file as
shown below, which is physically ordered by street address. (Note when there is a mix of
numerical numbers and character strings, numerical numbers come first, followed by character

sparse index containing only three index items. Show a possible scenario of index items, along
with pointers pointing to appropriate records in the data file. [Put your answer in the space below,

“Martial Arts R Us” (MARU) needs a database. MARU is a martial arts school with hundreds of students. The database must keep track of all the classes that are offered, who is assigned to teach each class, and which students attend each class. Also, it is important to track the progress of each student as they advance. Create a complete Crow’s Foot ERD for these requirements: • Students are given a student number when they join the school. The number is stored along with their name, date of birth, and the date they joined the school. • All instructors are also students, but clearly not all students are instructors. In addition to the normal student information, for all instructors, the date that they start working as an instructor must be recorded along with their instructor status (compensated or volunteer). • An instructor may be assigned to teach any number of classes, but each class has one and only one assigned instructor. Some instructors,…
Consider the following set of requirements for a Flight reservation database: We conduct numerous flights departing from and arriving at various airports. We maintain a record of airport codes and addresses. Here is our requirements: Each airline schedules many flights. A flight may be shared among multiple airlines, and therefore the flights can be scheduled by many airlines. When multiple airlines share the same flights, each flight can be scheduled by many airlines. The passenger capacity of each flight varies depending on the aircraft's size and can accommodate up to 220 passengers. We collect and store essential information such as the passenger's ID, name, credit card, and mileage plan number. To account for fluctuating prices, we must save the total cost at the time of booking as prices are subject to change. Every booking must be assigned to precisely one flight and be associated with at least one passenger. A newly introduced flight does not have any existing bookings.…
If you want to get the most out of this example, you should definitely begin by using a database that is "snapshot isolated" and is controlled by an airline. This will allow you to get the most out of this example. What if, rather than an operation that can be serialized, the improved overall performance of the airline was due to an execution that cannot be serialized?
27. Colton is working on the data structure that is to be used by Universal Bank to store the transactions of users to be displayed on their website interface when the user logs in. Load time needs to be fast, so a fast insertion time is mandatory. The data stored and loaded from the server is already in sorted order.so it is read into Colton's program in sorted order. The data structure does not need fast search times, and no deletion is allowed. The transactions will be shown on the website in order. What data structure would work well for Colton?
Answer the given question with a proper explanation and step-by-step solution. For this question use the file data1.csv The file contains information on various customers. Each customer has a unique customer id. The data also has information on age income and Gender of the customers. Space can be used as a delimiter for this file. Find the following: A) The total number of the rows in the file. B) The number of unique customer ids in the datafile. For this question create a set object which will only allow you to add unique customer ids. C) The program asks user to provide an id and prints information about that customer. Make sure to take care for the errors due to invalid id (i.e., id does not present in data). Print “id not found” when id is not found. Save the file as Solution1.java. You can use either File Reader or Scanner classes to read the data in the csv file. Your program should print the following after filling the blanks with the appropriate values Outcome: The total…
Take a "snapshot isolation" as an example for a database used by an airline. Is the decision to go with a method that cannot be serialized justified in the event that airlines manage to improve their overall performance?

Consider a basic database that stores information about students' grades. Create a database and offer a SQL query that returns a list of honour roll students (top 10%), ordered by grade point average.
You should definitely start with a database that is run by an airline and makes use of "snapshot isolation" if you want to get the most out of this example. What if the improved overall performance of the airline was caused by a non-serializable execution rather than a serializable execution?
We would like to develop a database that captures the following requirements. A University student can enrol in a course and at least in one major. In fact, a student can enrol in many majors within that course. During the semesters, a student can enrol in units. We want to capture in which year and in which semester a student enrolled in each unit. We have two semesters: Semester 1 and Semester 2. A unit has a code, a title and the number of credit points. We would like also to record the student’s GPA. A course has a code and a name. A major has a code and a name. Also, a major belongs to a course. A unit can be part of either a course or a major. A unit can also be shared across different courses and different majors. Important to note: Provide your design in a textual form, i.e. Entity(Attribute1, Attribute2, Attribute3, …). Make sure that the primary keys of each entity are underlined (Attribute1 in the example above) and foreign keys are indictated in bold (Attribute3 in…
A student database may include indexes on fields such as major, age, marital status, and home zip code in addition to the main key, which is the student's unique identifier (all secondary keys). Let's assume the school wants a list of MIS or CS majors over the age of 25 who are married and from the 45462 zip code OR a list of CS majors under the age of 25 who are single and from the 45462 the code. Is there a way to utilize indexes to restrict access to just the records that meet this criterion?
