Chapter 25, Problem 10E
Program Plan Intro
- Database tuning describes a group of activities that is used to optimize the performance of a database.
- Database tuning helps to analyze all the workloads that executes against a database.
- Database tuning helps to improve the performance of a query.
- It also improves the response time of a transaction or a transaction throughput.
Explanation of Solution
Examples on how tuning can be done
- The first example for tuning the schema and relational schema is to consider a course relation in a university database.
- This relation can be split into two relations.
- Another example for tuning the schema and relational schema is to consider a case where natural join of two relations account and deposit is required in a bank database.
- An example for tuning the buffer manager and transaction manager includes queries that computes tax deducted from account relation are best run at night.
- At this time no update to a customer’s account will be allowed...

In 32-bit MSAM, You were given the following negative array. write a program that converts each array element to its positive representation. Then add all these array elements and assign them to the dl register. .data myarr sbyte -5, -6, -7, -4.code ; Write the rest of the program and paste the fully working code in the space below.
the dl register should have the value 22 after summing up all elements in the array.

In recent years, growing demand has exposed the limitations of their fragmented processes and outdated systems. Different departments manage production schedules, raw material requirements, and finished goods inventory using a patchwork of spreadsheets and older software tools. These silos create inconsistent data, errors in stock levels, delivery delays, and customer dissatisfaction. Green Fields plans to implement an Integrated Inventory Management System to centralise production, procurement, inventory, and sales data to address these challenges. This technology aims to provide real-time visibility into stock levels, automate reorder points, and generate analytical dashboards for managers at both operational and strategic levels. Ultimately, the new system will streamline workflows, reduce…arrow_forward

Word FrequencyWrite a program that reads the contents of a text file. The program should create a dictio-nary in which the keys are the individual words found in the file and the values are the number of times each word appears. For example, if the word “the” appears 128 times, the dictionary would contain an element with 'the' as the key and 128 as the value. The program should either display the frequency of each word or create a second file containing a list of each word and its frequency.arrow_forward
- 3.) File Encryption and DecryptionWrite a program that uses a dictionary to assign “codes” to each letter of the alphabet. For example: codes = { ‘A’ : ‘%’, ‘a’ : ‘9’, ‘B’ : ‘@’, ‘b’ : ‘#’, etc . . .}Using this example, the letter A would be assigned the symbol %, the letter a would be assigned the number 9, the letter B would be assigned the symbol @, and so forth. The program should open a specified text file, read its contents, then use the dictionary to write an encrypted version of the file’s contents to a second file. Each character in the second file should contain the code for the corresponding character in the first file. Write a second program that opens an encrypted file and displays its decrypted contents on the screen.arrow_forwardReturns an US standard formatted phone number, in the format of (xxx) xxx-xxxx the AreaCode, Prefix and number being each part in order.

Here are some notes to help you work the problem: • strcpy(char *dst, char *src) copies the string at address src (including the terminating '\0' character) to address dst. It does not check the size of the destination buffer. You will need to know the hex values of the following characters:arrow_forward
