1. Difference between Structured Analysis and Object Oriented Analysis? Structured Analysis and Object Oriented Analysis are different techniques of developing a computer system.

2. Structured Analysis  In Structured Analysis, the focus is only on process and procedures. Modeling techniques used in it are DFD(Data Flow Diagram), Flowcharts etc. This approach is old and is not preferred

3. Object Oriented Analysis  Whereas in Object Oriented Analysis, the focus is more on capturing the real world objects in the current scenario that are of importance to the system. [2] It stresses more on data structure and less on procedural structure. Without actually identifying objects, what are you going to interact with, and whose state will you change. In this approach, objects are identified, their relationships among each other, possible states that each object can be in, and finally how all objects collaborate with each other to achieve a broader system goal are identified.

4. What is UML?  Unified Modeling Language (UML) is a standardized general-purpose modeling language in the field of software engineering. The standard is managed, and was created by, the Object Management Group.modeling languagesoftware engineeringObject Management Group  UML includes a set of graphic notation techniques to create visual models of software-intensive systems.

5. What is the Waterfall Model?  The waterfall model is a sequential design process, often used in software development processes, in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of Conception, Initiation, Analysis, Design, Construction, Testing and Maintenance.sequentialdesignsoftware development processeswaterfallAnalysisDesignTestingMaintenance

6. What is Software Lifecycle?  A software development process is a structure imposed on the development of a software product.developmentsoftware  Similar terms include software life cycle and software process. There are several models for such processes, each describing approaches to a variety of tasks or activities that take place during the process. Some people consider a lifecycle model a more general term and a software development process a more specific term. For example, there are many specific software development processes that 'fit' the spiral lifecycle model.software life cyclemodelstasks or activities

7. What is Software Prototype Model?  Software prototyping, refers to the activity of creating prototypes of software applications, i.e., incomplete versions of the software program being developed. It is an activity that occurs during certain software development and is comparable to prototyping as known from other fields, such as mechanical engineering or manufacturing.prototypes software programsoftware developmentprototypingmechanical engineering manufacturing  A prototype typically simulates only a few aspects of the features of the eventual program, and may be completely different from the eventual implementation.simulates aspectsfeaturesprogramimplementation

8. What is Software Spiral Model?  The spiral model is a software development process combining elements of both design and prototyping-in-stages, in an effort to combine advantages of top-down and bottom-up concepts. Also known as the spiral lifecycle model (or spiral development), it is a systems development method (SDM) used in information technology (IT). This model of development combines the features of the prototyping model and the waterfall model. The spiral model is intended for large, expensive and complicated projects.software development processdesign prototypingtop-down and bottom-upinformation technologywaterfall model

9. What is Software Object-Oriented Model?  Object-Oriented Modeling, or OOM, (Object Oriented Programming - OOP)is a modeling paradigm mainly used in computer programming. Prior to the rise of OOM, the dominant paradigm was procedural programming, which emphasized the use of discreet reusable code blocks that could stand on their own, take variables, perform a function on them, and return values.computer programmingprocedural programming

10. What is Software Assembly Model?  Assembly Modeling is technology and methods used by Computer-aided design and Product visualization computer software systems to handle multiple files that represent components within a product. The components within an assembly are represented as solid or surface models.Computer-aided designProduct visualizationsolidsurface

11. What is Software Mixed Model?  A mixed model is a statistical model containing both fixed effects and random effects, that is mixed effects. These models are useful in a wide variety of disciplines in the physical, biological and social sciences. They are particularly useful in settings where repeated measurements are made on the same statistical units, or where measurements are made on clusters of related statistical units.fixed effectsrandom effectsstatistical units
