Session data is stored in the database using a technique called serialization. Serialization is the process of converting a data structure into a stream of bytes that can be sent over a communications channel.
The following are some of the benefits of using serialization:
- Serialized data can be transmitted from one computer to another without any loss or corruption
- It also makes it possible for multiple computers to share and update the same database
- It's also easier to read and write sequential data, which means that it's easier to perform certain tasks like sorting, filtering, and grouping
