Study Notes
Third-Generation Languages (3GL)
- Characterized by high-level abstraction and closer to human languages than machine code.
- Often associated with imperative and procedural programming paradigms.
Fourth-Generation Languages (4GL)
- Aimed at reducing development time and cost compared to 3GL, focusing on problem-solving rather than coding.
- Distinct from 3GL by offering higher-level abstractions that often include database interaction, report generation, and user interface design.
Autocoder
- An early example of an assembler language, which translates assembly code to machine language.
Development Speed of 4GL
- Emphasizes rapid application development, allowing for quicker iterations and shorter development cycles compared to 3GL.
High-Level vs. Low-Level Languages
- High-level languages offer more abstraction, leading to easier coding and maintenance, as they manage complex tasks without detailed hardware management.
Role of Compiler or Interpreter
- Translates high-level programming code into machine-readable code, bridging the gap between human understanding and machine execution.
Programming Paradigms
- Key paradigms include imperative, functional, object-oriented, and declarative; procedural and event-driven are also common. Certain types, like object-oriented programming, have distinct characteristics.
Unstructured Programming
- Characterized by a lack of rigorous structure, making it harder to manage and maintain code.
Top-Down Design Model
- In structured programming, this model promotes breaking down a program into smaller, manageable components or modules for easier understanding and debugging.
High-Level Programming Languages
- Examples include Python, Java, and C++, which prioritize readability and ease of use.
Difference Between 4GL and 5GL
- 4GL focuses on ease of use for data manipulation and management, while 5GL emphasizes artificial intelligence and uses knowledge-based systems to facilitate programming.
Low-Level Languages
- Known for close interaction with hardware, making them less portable and generally more complex than high-level languages.
Advantages of High-Level Languages
- Provide better readability and maintainability, thus reducing development time and improving collaboration among programmers.
Challenges of Low-Level Languages
- Require detailed knowledge of hardware, making them prone to errors and often cumbersome for complex tasks.
Role of Programmer in 5GL
- In 5GL, the programmer typically defines the desired outcomes or goals, and the language’s AI capabilities help achieve those through automated programming processes.
