Data Deserialization

Deserialization is essentially the reverse process of serialization. See: 'Serialize'.

Definition of Deserialization:

In the context of data management, serialization and deserialization are key to storing data persistently (like writing data to disk) and communicating data between different systems (for example, through APIs). It allows the structured, complex data of one system to be understood by another, irrespective of the language or architecture they're built with.

Deserialization is essentially the reverse process of serialization. It is the process of converting the serialized format back into a usable object in the program. This process is used to extract the data or the state of the object from the stored or received serialized format.

Note: Deserialization can present potential security risks, especially when dealing with unknown sources. Deserializing data from an untrusted source can lead to what's known as deserialization attacks, where malicious data is loaded into an object, potentially leading to code execution or privilege escalation. Therefore, it's important to ensure that any serialized data is appropriately secured and validated.
