What are the characteristics of a system? Describe how structured systems differ from object oriented systems? ›

While the structured approach provides cleat-cut steps (planning-analysis-design- implementation) from the beginning to the end of the systems development life cycle, the object- oriented approach does not – there is no clear-cut step in moving from analysis to design.

The main difference between structured and object oriented programming is: The structured programming allows developing a program using a set of modules or functions. while the object oriented programming allows constructing a program using a set of objects and their interactions.

Structured Analysis: Structured Analysis is suitable for projects with straightforward requirements and relatively simple systems. Object-Oriented Analysis: Object-Oriented Analysis is more suitable for handling complex systems with evolving requirements, as it offers greater flexibility, modularity, and scalability.

The structure, or building blocks, of object-oriented programming include the following: Classes are user-defined data types that act as the blueprint for individual objects, attributes and methods. Objects are instances of a class created with specifically defined data.

Structured programming follows top-down approach. Object oriented programming follows bottom-up approach. Structured Programming is less secure as there is no way of data hiding. Object Oriented Programming is more secure as having data hiding feature.

Structured programming is a method of organizing and coding programs that can provide easy understanding and modification, whereas objectoriented programming (OOP) consists of a set of objects, which can vary dynamically, and which can execute by acting and reacting to each other, in much the same way that a real-world ...

In object-oriented programming, objects have identity, state and behaviors associated with them. Abstraction means that hiding implementation code that is not necessary for use by other objects. This helps make it easier for developers to change or add to objects over time.

What are the features and advantages of object-oriented programming? The features of object-oriented programming are polymorphism, encapsulation, inheritance, data abstraction, message passing, and dynamic binding. The advantages are that it makes code reusable, more efficient, and more flexible.

Object-oriented methodology relies on three characteristics that define object-oriented languages: encapsulation, polymorphism, and inheritance.

The main difference between structured and object oriented programming is that structured programming helps to develop a program using a set of modules or functions while object oriented programming helps to construct a program using a set of objects and their interactions.

Obviously you can blur the distinctions according to your programming style, but generally a struct is a structured piece of data. An object is a sovereign entity that can perform some sort of task. In most systems, objects have some state and as a result have some structured data behind them.

While structural analysis deals with the calculations and observations of load and stress, structural design decides the dimensions of the structural members by using those structural analysis findings. Once the above has been confirmed, projects can then move into the phase of structural design.

Structured programming is a programming paradigm aimed at improving the clarity, quality, and development time of a computer program by making extensive use of the structured control flow constructs of selection (if/then/else) and repetition (while and for), block structures, and subroutines.

The four pillars of OOPs (object-oriented programming) are data abstraction, encapsulation, inheritance, and polymorphism.

Structured vs Object Oriented Methodology. Structured design breaks a system down into functional modules. Each module can be described as having inputs, processing, and outputs. Structured de sign is a top-down decomposition of system functionality, while object oriented design focuses on system behavior.

It provides more flexibility and abstraction as compared to structured programming. It is more difficult to modify structured program and reuse code as compared to object-oriented programs. It is less difficult to modify object-oriented programs and reuse code as compared to structured programs.

In the object-oriented approach, we see the world as a set of objects, and every action is a function of one of those objects. The functional approach sees the world as a set of possible actions, and objects only hold information. OOP concentrates on modeling reality: the entities and the relationships between them.

System design is the designing the software/application as a whole [high level] that may include analysis, modelling, architecture, Components, Infrastructure etc. whereas the objected-oriented design is the set of defined rules/concepts to implement the functionalities within a software.

In an object-oriented system, all data is represented as discrete objects with which the user and other objects may interact. Each object contains data as well as information about the executable file needed to interpret that data.
