Serialization and De-serialization

Data structures or object states can be transformed using the serialization and deserialization procedures into a format that can be transferred, saved, and rebuilt.

  • Serialization: The state of an object converting to a byte stream.
  • De-serialization: Reverse process in Serialization. Byte stream convert to actual java object in memory.

Benefits of Serialization and De-serialization:

  • Data persistence : To save an object in database
  • Communication : To exchange data between different part of system or between different network.(To travel Object across a network)
  • Performance : Improve data storage(Memory) efficiently.

Mechanism of the Serialization and De-serialization

Serialization :

  1. Create an object : An object is create using program.
  2. Serialization : Convert object to byte stream using created object (Can we use Json,XML or Binary).
  3. Storage : Converted byte stream store in a file , database or over network.

De-serialization :

  1. Byte stream retrieval : Get byte stream from storage(file,database or over network).
  2. De-serialization : Convert byte stream to back on that object using got byte from storage.
  3. Usage of Object : Use that object in program
