Agile Development:

• It is a methodology followed in software development, wherein a large project is broken down and performed as a collection of sub projects.
• And each sub project is assigned a team for its project development phase, analysis of the requirements, coding phase and testing phase, and so on...

Components Based Development:

• They are projects to enhance the speed of software development. Components based development, grouping of objects into software component suites is done.
• These components are then combined to create a large-scale application. In the new age information systems, components are kept available in cloud services for easy deployment.
• Examples of such systems include shopping carts, user authentications, search engines, online catalogues, where assembling and integration of software components is done...

Explanation of Solution

Features of Mobile Application Development:

• The growth of smartphone industry and the escalation of its users has made companies understand the importance of mobile application development for improving their business values.
• New generation are shifting from personal computer towards increased usage of mobile phones.
