Hello Everyone,

You might be aware that in software engineering there are so many different models which are used to building the whole software and its process.

Here is the first and basic model which is followed by developers and engineers which is the traditional and simplest model.

Waterfall Model :

The name suggests and defines that we are gonna follow the waterfalling means downward approach in this model. It’s the first approach in the software development process.

It is also called the classical life cycle model or linear sequential model.

In this, any phase of the development process begins only if the previous phase is completed.

In this model, there are mainly five different components important which are :
— Requirement Analysis
— Design
— Implementation
— Verification/Testing
— Maintenance

Working of Digital Camera :

  • Based on CCD Mechanism
  • CCD consists of cells arranged in a fixed array on the surface/behind the lens.
  • CCD cells get charged by the intensity of light.
  • This charge generates a voltage which is then fed to the A-D Converter.
  • It converts charge voltage to a digital value.
  • These values are stored in camera memory.
  • This data can be moved from camera memory to computer memory, other memory devices, and so on.

Introduction to Data Mining

  • Data Mining is the process of collecting large amounts of data and transforming that data into useful information
  • Data mining, also popularly known as Knowledge Discovery in Databases (KDD), refers to the nontrivial extraction of implicit, previously unknown, and potentially useful information from the databases.
