Object Oriented Analysis, Object Oriented Design, and Software Design

 Object Oriented Analysis

Object Oriented Analysis is a software engineering approach that is used to model, analyze, and create software systems based on the ideas of "object-oriented programming". It is a process of identifying the objects, their relationships, attributes, and behaviors in a system. The typical systems lifecycle first considers the outputs the system needs, then builds the database to include the information required to generate those outputs. The documentation follows the "input-process-output" methodology, in which the inputs are determined in order to produce a particular outcome. The database and the programs that use the database are used in the process of converting the identified inputs into the required outputs. Object-oriented analysis is focused on units (classes) that mix data and procedures, as opposed to the traditional systems analysis life cycle, which views data and data manipulation as two separate elements of the system.


Object Oriented Design

Object-Oriented Design is a software engineering approach that is used to create software systems in accordance with object-oriented programming principles. It involves turning the needs determined by object-oriented analysis (OOA) into a software system design. The system is regarded as a group of items. The objects share the same state, and each object is in charge of maintaining its own state information. Tasks created with a single objective cannot update or refer to data from other objects. Every object contains internal data that reflects its current state. A class is made up of related items. To put it another way, every item falls under a class.

Software Design

Software design is the process of defining the architecture, components, interfaces, and other characteristics of a software system to meet specific requirements. It involves creating a detailed plan or blueprint for developing a software system that meets the needs of its users and stakeholders. The first step in the SDLC (Software Design Life Cycle) is the software design phase, which shifts the focus from the problem domain to the solution domain. In software design, the system is viewed as a collection of parts or modules with distinct behaviors and boundaries. The Following purpose of Software Design is Correctness, Completeness, Efficiency, Flexibility, Consistency, and Maintainbility.

  I.                 Details of the event/activity On May 28, 2024, at Room 508, Gordon College. I had to attend to the Seminar called “Principles and Fundamentals of Animation” by two resource speaker Linkel Rae L. Lee, and Prestian Mark L. Lee, both are animators from KAMBALLEE. With the topic that they present are the “Mastering the Principles and Fundamentals of 2D Animation”, Demonstration to create an Animation Using “Toon Boom”, and showcasing their work like their own upcoming show in an episode title “Nightmare Creep”.   II.              Reflections on the webinar/activity give rise to (learnings) The Seminar is very interesting, it uses all of the technique of animation, and how animation works, from the simple movement to advance details. It also understands the...

Event Title: “Company Visit at Wistron”

Image
 I. Details of the event/activity We got the chance to take part in an electronics company tour at Wistron during this event. During the visit, we took part in a guided tour where we were given valuable insights into the company's operations and procedures. The corporate representatives gave us a thorough overview of Wistron's operations by walking us through numerous elements. II. Reflections on the webinar/activity give rise to (learnings) We got really useful information about how to handle and repair electronics from the Wistron Company during our tour. We discovered throughout the tour how carefully they inspect and fix the things that are sent to them. The import and export of different electronic products, including laptops, cellphones, and monitors, is the area of expertise for Wistron Company. To meet the expectations of customers, they make sure that every product satisfies strict quality standards. I learned useful information on how to take care of electrica...
