Chapter 17, Problem 1OC
Program Plan Intro
Systems development life cycle (SDLC):
- It is an overall process for developing
information systems. - It contains a series of planned activities for developing software products.
- It denotes foundation for all systems development methods and many activities are associated with each phase.
- The activities includes:
- Determining budgets.
- Gathering system requirements.
- Detailed user documentation.
- The SDLC initiates with a business need, it proceeds to satisfy that need and ends when system benefits would not at all be significant than maintenance cost.
- The SDLC is comprised of seven phases that includes:
- Planning
- Analysis
- Design
- Development
- Testing
- Implementation
- Maintenance
Expert Solution & Answer
Explanation of Solution
Most Critical Phase in SDLC:
- All phases are important to build a social networking website, but the most critical phase in the System development life cycle is the maintenance phase.
- During this phase, the organization performs corrections, changes and up gradations to ensure that system meets requirements.
- Corrective maintenance would make system changes to flaws in design, errors in coding or issues in implementation.
- Preventive maintenance would make system changes to reduce chances for system failure in future.
- In this phase, the social network will grow, develop, attract users, and evolve depending on what the users prefer.
- The success of the social network will be decided in this phase.

Implementation of an Integrated Inventory Management System at Green Fields Manufacturing” Green Fields Manufacturing is a mid-sized company specialising in eco-friendly home and garden products. In recent years, growing demand has exposed the limitations of their fragmented processes and outdated systems.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…

- 5. 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_forward3.) 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.
