Study Notes
Data Storage Challenges
- Main memory is not used to store databases because of its limited capacity and volatility, which makes it unreliable for long-term data storage.
Limitations of Secondary Storage
- Hard disks and SSDs are not sufficient for handling increased data volumes due to their limited capacity, slow access times, and high cost.
Big Data Solution
- The primary solution for handling enormous amounts of data is to use distributed storage systems, such as cloud storage, which provide scalability, high availability, and low cost.
Data Deletion
- When a user deletes a post from their social media account, the data is not immediately deleted but rather marked for deletion and may still be stored on the server for a period of time before being permanently deleted.
Example of Big Data Handling
- Facebook is an example of an organization that handles an enormous amount of data every day, with billions of users and a vast amount of user-generated content.
