Mastering Requirement Engineering: A Software Engineer's Guide

What is Requirement Engineering?

  • The systematic process of understanding, documenting, and managing the needs of stakeholders for a software system.
  • Focuses on defining *what* the software should do, not *how* it should do it.
  • Critical for project success, minimizing rework, and ensuring user satisfaction.
  • Involves collaboration between developers, clients, and end-users.

The Requirement Engineering Process

  • Requirements Elicitation: Gathering information from various sources.
  • Requirements Analysis: Analyzing elicited information to identify conflicts and ambiguities.
  • Requirements Specification: Documenting requirements clearly and unambiguously.
  • Requirements Validation: Verifying that the documented requirements meet stakeholder needs.
  • Requirements Management: Controlling changes and maintaining consistency throughout the software development lifecycle.

Requirements Elicitation Problem

  • Stakeholders may have conflicting needs and priorities.
  • Stakeholders may have difficulty articulating their needs clearly.
  • Implicit requirements are often overlooked.
  • Communication barriers can hinder effective elicitation.
  • Requirements may change over time, creating inconsistencies.
  • Difficulty in managing large number of stakeholders and their requirements.
  • Incomplete or inaccurate information provided by stakeholders.
  • Challenges in balancing functional and non-functional requirements.

What is Stegnography and list two examples.

Unveiling the Secrets: Understanding Steganography in Cybersecurity What is Steganography? Steganography is the art and science of hiding information within other information. It focuses on concealing the very existence of a secret message. Unlike cryptography (which scrambles messages), steganography aims to make hidden data undetectable. It's a powerful tool for covert communication and data exfiltration. Often used in conjunction with cryptography for enhanced security. Steganography Examples in Cybersecurity Hiding data within an image file: Modifying least significant bits (LSBs) of image pixels to embed secret data. The changes are usually imperceptible to the human eye. Embedding data within audio files: Similar to images, small modifications to audio waveforms can hide information without noticeably altering the sound quality.

What is LZW compression? Explain with example.

Decoding the Magic of LZW Compression: A Data Compression Deep Dive What is LZW Compression? Lempel-Ziv-Welch (LZW) is a lossless data compression algorithm. It works by replacing repeating sequences of data with shorter codes. It's widely used in GIF image format and other applications. Highly effective for data with repeating patterns. How LZW Compression Works: A Step-by-Step Guide Starts with a dictionary containing single characters. Reads the input data character by character. Concatenates characters to form strings. When a string is not found, it's added to the dictionary with a new code. The code for the longest matching string is written to the output. This process continues until the entire input is processed. LZW Compression Example: Initial Dictionary: {'A': 1, 'B': 2, 'C': 3} Input String: "ABABCABABCACC" Processing: - 'A' is encoded as 1. - 'AB' is encoded as 4 (added to diction...

Explain different compression techniques with example.

Mastering Data Compression: A Comprehensive Guide Lossless Compression Techniques Run-Length Encoding (RLE):  Represents consecutive repeating characters with a single count and character. Example: "AAABBBCC" becomes "3A3B2C". Huffman Coding: Assigns shorter codes to frequently occurring symbols and longer codes to less frequent ones. Example: In text, "e" gets a shorter code than "z". Lempel-Ziv (LZ77 & LZ78):  Identifies repeating patterns and replaces them with pointers to earlier occurrences. LZ77 uses a sliding window, LZ78 uses a dictionary. Arithmetic Coding: Represents data as a single fractional number, encoding probability. More efficient than Huffman for many cases. Lossy Compression Techniques JPEG (Joint Photographic Experts Group): Discards some image data, particularly high-frequency components, which are less noticeable to the human eye. MPEG (Moving Picture Experts Group): Uses techniques like motion compen...

what is type conversion in python? Explain with the suitable example.

Data Compression: Mastering Type Conversion in Python What is Type Conversion? Type conversion, also known as type casting, is the process of changing a variable's data type from one to another. Python supports both implicit (automatic) and explicit (manual) type conversion. Implicit Type Conversion Python automatically converts data types in certain situations to prevent errors. Example: Adding an integer to a float results in a float. Explicit Type Conversion We use built-in functions like `int()`, `float()`, `str()`, `bool()` etc. to explicitly change data types. Example: Converting a string "10" to an integer using `int("10")`. Example: Data Compression Context Imagine you're storing compressed file sizes (originally floats) in a database designed for integers. Explicit type conversion (using `int()`) would truncate the decimal part, losing precision but saving space. This is a type of lossy compression. Converting from a larger data t...
