what is the need of data base
Answers
Answer:
The various reasons for which we require databases are:
To manage large chunks of data: Yes, you can store data into a spreadsheet, but if you add large chunks of data into the sheet, it will simply not work. For instance: if your size of data increases into thousands of records, it will simply create a problem of speed.
Accuracy: When doing data entry files in a spreadsheet, it becomes difficult to manage the accuracy as there are no validations present in it.
Ease of updating data: With the database, you can flexibly update the data according to your convenience. Moreover, multiple people can also edit data at same time.
Security of data: There is no denying the fact that your data is less secure in spreadsheets. Anyone can easily get access to file and can make changes to it. With databases you have security groups and privileges you set to restrict access.
Data integrity: Data integrity also becomes a question when storing data in spreadsheets. In databases, you can be assured of accuracy and consistency of data due to the built in integrity checks and access controls.
