What is Data?
Data is a collection of information. It will be in any form such as geographical information which google uses for Google maps, messages, medical information, banking, insurance information, etc.., everything which we are collecting and storing is data.
In the earlier stage, we used to collect the data and write it on paper and notebooks.
After, when computers and mobile became popular we used to store the data in the drives using software such as Excel, Word, PowerPoint, and so on.
But there we have a limitation, for example, we can store up to 10,48,576 lakh rows and 16,384 thousand columns in Excel. After a certain period, data became evolving and we had a storing and reuse of data issue. To tackle this, we have developed Databases.
