Assignment 5 Due: 3:00pm on December 12, 2019 (for both in-class and online students) Total points: 30 In this assignment, you will have a chance to implement the hash-join algorithm for a DBMS. You can use C, C++, Java, or any other high-level programming language to write the program. However, your program should include sufficient comments to make it readable. You need to turn in: 1. A brief report/description about your program design and implementation (e.g., high-level program diagram and data/file structures and program usage) 2. Your program source code 3. Proof of compilation (e.g., the screen snapshot of a successful compilation) 4. Sample execution outputs Please assemble all the above required contents in a single Word or PDF file for your submission. The program specification is given as follows: Let R1 and R2 be two relations with all integer attributes. Tuples in these two relations are sequentially stored in two data files, respectively. Use the hash-join algorithm to implement a join (equijoin) of R1 and R2. Assume that the hash function is f = mod N, where N is the number of buckets allowed in your hash structure/table. Your program should allow a user to choose the joining attributes from the two relations, i.e. performing R1.a = R2.b for any chosen pair of a and b, where a is the i-th attribute in R1 (1 < i < 3) and b is the j-th attribute in R2 (1 < j < 4). For example, a user may want to perform R1.a2 = R2.b3. Your program should display the join result and output the selectivity of the join. You may request a user to interactively input the necessary parameters, such as the data file names for R1 and R2, the number of tuples in each relation, and the joining attributes (e.g., 1 for the 1st attribute, 3 for the 3rd attribute). Use your program to perform several joins for different relation instances of R1 and R2.

Problem 1. Array of Structures (30 Points) The purpose of this problem is to give you some practice working with structures, hierarchical structures and arrays of structs. Using the data file below design a hierarchical struct to organize the data. Then declare an array of structs for the reservations. The data file contains ten reservations. There are 8 columns of data: party name, size, date and time for the reservation, phone number, email address, credit card number and expiration date for the credit card. The data can be read from the file below so you will not need to type it in repeatedly. Once you have populated the array with data perform the following tasks: * Write a function that will print out to the screen the information for one reservation. * In the main program write code that prompts the user to enter a date in the form MM DD YYYY * Call the function to print out all reservations on that date. You can make a loop that calls the print function repeatedly or you can put that code inside the print function. TEST CASES: April 30, 2023 and May 12, 2023. In this example you need to carefully consider what data types to use. For example, the credit card number is too large to fit into an int or unsigned int. A string type will be fine in this case. http://uahcs.org/CS121/data/dinner_reservations.txt The file contains the following data: NAME SIZE DATE TIME PHONE EMAIL CREDIT CARD NO EXPIRE G.

Execute the code shown below using the Tomasulo's algorithm. Use the tables as shown in Figure 3.11 to show the states of the instructions, reservation stations, and registers for the following problems. (a) After all instructions are issued, but none has started execution. (b) One cycle after instruction fld enters Write Result stage. (c) Tomasulo's algorithm allows out-of-order completion. Now, suppose the first instruction fdiv.d f6, f2, f4 causes a divide-by-0 exception. Briefly explain possible issues of exception handling by Tomasulo's algorithm. You need to show two sets of tables, one for each of the first two problems above. The code sequence is: fdiv.d f6, f2, f4 fld f6, 32(x2) fadd.d f2, f6, f4 Assume that the latencies of fmul.d, fld, and fadd.d are 12, 8, and 1 cycle, respectively. Figure 3.11: Reservation stations and register tags shown when all of the instructions have issued but only the first load instruction has completed and written its result to the CDB. The second load has completed effectively the array Mem[] to refer to the memory. Remember that an operand is specified by either a Q field or a V field at any time. Notice that the fadd.d instruction, which has a WAR hazard at the WB stage, has issued and could complete before the fdiv.d initiates.

00:01 So, in this question we have to make a implementation of a hash join algorithm for a database management system dbms.

00:08 So, here is a template that used to structure your report and program and you can adapt it according to your programming language of choice like c, c++, java etc.

00:20 So, the first is report and description.

00:23 So, in the report and description you have to design a program, program implementation and data files structure and also program usage.

00:34 So, this is all that you have to mention in report and description.

00:39 Now, coming to the second part which is a program source code.

00:42 So, here include your well commented source code with explanation for critical section.

00:48 Now, coming to the proof of compilation.

00:50 So, provide a screenshot or a snippet showing the successful compilation of your program.

00:58 Next is sample execution output...
