Suppose you are involved in developing a database system for the ticket booking database of ABC bus company. The operation of the ticket booking can be described as follows. They have a file of booking that they provide to their clients. Each type of ticket has a unique ticket code, as well as, quantity available and a price. • They have a file of clients. Each client is given a unique client number. This file also contains client telephone, and client name. The client name consists of first name and last name. A client may make zero, one or more bookings at a time, and a booking is always placed by one client only. Information as to booking includes the booking date, and quantity. The system is allowed to booking up to 5 bookings per day, bookings limit which is used to validate customer. A booking may involve one or more than one tickets and a ticket involved in more than one booking. may be Given this information, draw an ER diagram for this ABC bus company. Identify and label the primary key(s) of each entity, relationships and the foreign keys required for creating the relational model.

You should concentrate your efforts on avoiding an argument that centers on how well deep access performs in compared to shallow access, and you should make the case for utilizing deep access rather than shallow access from the standpoint of a programmer.
Suppose you were asked to define a class MetaDisplay in Java, containing amethod static void printTable(String r); the method takes a relation name r asinput, executes the query “select * from r”, and prints the result out in tabularformat, with the attribute names displayed in the header of the table. What do you need to know about relation r to be able to print the result in the specified tabular format?
From the standpoint of a programmer, make a case for utilizing deep access as opposed to shallow access, and try to avoid making an argument that relies on how well deep access performs in contrast to shallow access.
The following java function executes an SQL query based on the inputs from the combo boxes and text box from the screen shown and is supposed to return a list of items that match the query. The input string is a string of the field, operator and criteria text from the boxes separated by commas. However, the method is not currently functional and must be modified to enact the query. Modifiy the function so that it works properly.

A user wants to write a C program for manipulating student records. The program contains a function for accessing the student file. The user wants to add some records to the file. Which of the following line of code is used to open the student file for implementing this functionality? Choose an answer A fp = fopen ("studentfile.dat", "r"); B ch = fgetc(fp); C fp = fopen ("studentfile.dat", "w"); D fputc (ch, fp);
When advocating the superiority of deep access versus shallow access as a programmer, you should attempt to avoid relying only on performance reasons.
A server program written in one language (for example, C++) provides the implementation of a Person object (class) that is intended to be accessed by clients that may be written in a different language (for example, Java, PHP, C#). The client and server computers may have different hardware, but all of them are attached to an internet.Describe the problems due to each of the five aspects of heterogeneity that need to be solved to make it possible for a client object to invoke a method on the server object.
Suppose df is a Pandas DataFrame that contains several columns, including a single column containing lengths, as measured in kilometres. This column has a label containing the string 'km', which uniquely identifies it. Write a function km_to_miles, which accepts such a DataFrame df, and adds a new column on the right-hand side which contains the same length data converted into miles. The label for this new column should be the same as the label of the original length data, but with the string 'km' replaced with 'miles'. For the purposes of this question, assume a kilometre is equivalent to 0.621371 miles. (on python)
Consider the Student class in the provided student.py file. Each student has a name, an id anda list of courses taken. A course is represented as a list with three items to indicate the coursename, semester taken and grade. For example, [‘comp1008’, ‘S24’, 76.3] represents this coursewith a final grade of 76.3. Complete all the functions in the provided a4.py file.
For PyTorch and TensorFlow, I try to understand How is the overall file organization on disk for both frameworks? Do they store a bunch of smaller files, a few big files? Where is the metadata kept? Is there one file that has the metadata for the entire dataset/ is the metadata sprinkled in the various files. I appreciate if you can give me a detailed answer.
