Define Component Level Design In Software Engineering

In a context of object-oriented software engineering a component shown in a UML diagram. Software design is generally considered a two-step process.

However the meaning of component differs according to how software engineers use it.

Define component level design in software engineering. Understanding skill and knowledge type of user etc based on the users profile users are made into categories. The software needs the architectural design to represents the design of software. Information obtained from the class-based models flow models and behavioral models serve as the basis for component design.

From each category requirements are gathered. Component-based development CBD is a procedure that accentuates the design and development of computer-based systems with the help of reusable software components. Architectural design also referred to as high-level design and top-level design describes how software is organized into components.

Component level design establishes the algorithmic detail required to manipulate data structures effect communication between software components via their interfaces and implement the processing algorithms allocated to each component12. System design is the process of designing the elements of a system such as the architecture modules and components the different interfaces of those components and. IEEE defines architectural design as the process of defining a collection of hardware and software components and their interfaces to establish the.

In this section of Software Engineering Software DesignIt contain Software Component Level Designs MCQ Multiple Choice Questions AnswersAll the MCQs Multiple Choice Question Answers requires in depth reading of Software Engineering Subject as the hardness level of MCQs have been kept to advance levelThese Sets of Questions are very helpful in Preparing for various Competitive Exams. Background Component-level design occurs after the first iteration of the architectural design It strives to create a design model from the analysis and architectural models The translation can open the door to subtle errors that are difficult to find and correct later Effective programmers should not waste their time debugging they should not introduce bugs to start with. The component level design for the software completely describes the internal details of the each software component.

IEEE defines architectural design as the process of defining a collection of hardware and software components and their interfaces to establish the framework for the development of a computer system This framework is established by examining the software requirements document and designing a model for providing implementation details. The processing of data structure occurs in a component and an interface which allows all the component operations. The component-level design provides a way to determine whether the defined algorithms data structures and interfaces will work properly.

Initially the focus is based on the profile of users who will interact with the system ie. User task environmental analysis and modeling. Detailed design describes the desired behavior of these components.

The component-level design transforms structural elements of the software architecture into a procedural description of software components. Note that a component also known as module can be defined as a modular building block for the software. With CBD the focus shifts from software programming to software system composing.
