• It can save time and money by finding important information quickly.

Challenges:

• Data Mining needs good data to work well.
• Understanding the results can sometimes be tricky.

Ethical Considerations:

• Data Mining needs to be done responsibly, respecting people’s privacy and following laws.
• It’s important to use data mining for good purposes and not to harm people.

What is Big Data?

Definition:

• Big Data means lots of data that’s too big and complicated to handle with normal methods.

Characteristics:

1. Lots of Data:
   • Big Data involves huge amounts of information from different places like social media and sensors.
2. Fast Data:
   • It comes in quickly and needs to be looked at fast to find useful stuff.
3. Different Types:
   • Big Data includes all kinds of data, like numbers, words, pictures, and more.
4. Making Sure it’s Good:
   • Big Data might have mistakes or be hard to trust, so it needs to be checked carefully.

Technologies:

1. Using Lots of Computers:
   • Big Data needs special computer systems that can work on lots of data at once.
2. Different Kinds of Databases:
   • There are special databases that can store and organize Big Data in ways that make it easier to use.
3. Putting Data Together:
   • Big Data systems help bring different types of data together so it can be analyzed.

Applications:

• Big Data is used in many areas like business and science to learn things from data that can help make better decisions.

Challenges:

1. Storing and Working with Data:
   • It’s hard to keep all the data and to work with it quickly.
2. Putting Data Together:
   • Making different kinds of data fit together can be tricky.
3. Keeping Data Safe:
