Before we move onto the Weka tool, we need some ideas about data. In previous days peoples maintained their business details manually, handwritten data records were very important those days. That record helped them to analyse the data to make future decisions. But it needs lots of paperwork, it is time-consuming. Nowadays that data is maintained through the computer because our life is embedded with data, for example, our name is a kind of data and our living place, date of birth, in our government provides aadhar number that is also kind of data, in schools, students particulars, in supermarkets customer details, product details, customer purchase details, in bank account holder details, credit card holder details etc\u2026. We don't know about the importance of our information, but that data is important to some other people to develop their business. You can think about how it is possible, one product seller wants to sell their product in a place, but he doesn't know anything about that place and people, so they want to study that place and get a decision to sell their products. It all happens by their own thinking. <\/p>\n\n\n\n
If we collect our data properly, we can use that data to analyse our business understanding. Properly collected is without spelling mistakes, without missing values, or without duplicate values. Data handling is an important role of every organization. Without data, we can\u2019t do anything. In this blog, we are going to see one important data mining tool. <\/p>\n\n\n\n
