Chapter 3, Problem 11RQ
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 that provide GUI tools in order to perform tasks are as follows:
- SQL Server
- Oracle Database
- MySQL
Data Manipulation Language (DML):
This is used for manipulation like, querying, insertion, updating, and deletion of data.
Query to create table “EMPLOYEE”:
CREATE TABLE EMPLOYEE
(emp_id number(10) NOT NULL,
emp_name varchar2(50) NOT NULL,
city varchar2(50),CONSTRAINT emp_pk PRIMARY KEY (emp_id));
Explanation:
The above query is used to create the table “EMPlOLYEE”. The attribute “emp_id” is declared as “NUMBER”, “emp_name” and “city” is declared as “varchar”. Here, the attribute “emp_id” is set as primary key.

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In recent years, growing demand has exposed the limitations of their fragmented processes and outdated systems.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. Testing Hint: We be exact on the format of the number when testing this method. Make sure you think about how to convert 33 to 033 or numbers like that when setting your string format.

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
