PRTOTYPING MODEL
A prototype is a toy implementation of the system. A prototype usually exhibits limited functional capabilities, low reliability, and inefficient performance compared to the actual software. A prototype is usually…
Explain Iterative waterfall model
In this model feedback paths for error correction as & when detected later in a phase. Though errors are inevitable, but it is desirable to detect them in the same…
What is feasibility study? What are the contents we should contain in the feasibility report?
Feasibility study – The main aim of feasibility study is to determine whether it would be financially and technically feasible to develop the product. A feasibility study is an initial look…
Limitations of waterfall model
The waterfall model, sometimes called the classic life cycle, suggests a systematic, sequential approach to software development that begins with customer specification of requirements and progresses through planning, modeling, construction,…
Explain the different phases involved in waterfall life cycle.
Modeling Phase/Feasibility studyIn this phase we view the software product as part of a larger system or organization where the product is required. This is basically a system view where…
Different software life cycle models
Many life cycle models have been proposed so far. Each of them has some advantages as well as some disadvantages. A few important and commonly used life cycle models are…
Explain Software Development Life Cycle
LIFE CYCLE MODELSystem Development Life Cycle (SDLC) is the overall process of developing information systems through a multi-step process from investigation of initial requirements through analysis, design, implementation and maintenance. A…
Need of software engineering
The need of software engineering arises due to higher rate of change in user requirements and environment on which the software is working.1. Large software -If the size of software become large…
What is data modeling? Give 5 examples for data modeling
Data modeling is the act of exploring data-oriented structures. Like other modeling artifacts data models can be used for a variety of purposes, from high-level conceptual models to physical data…
Explain Agility and Agile Process Model
Agile model is a combination of iterative and incremental process models with focus on process adaptability and customer satisfaction by rapid delivery of working softwareAgility:Agility is dynamic, content specific, aggressively…
