Why Protocol Buffers?

• Protocol buffers are Google's language-independent, platform-independent, extensible mechanism for serializing structured data – think XML, but smaller, faster, and simpler.
• You define how you want your data to be structured once, then you can use special generated source code to easily write and read your structured data to and from a variety of data streams and using a variety of languages.
• Protocol Buffers are Schema Of Messages. They are language agnostic.
• They can be converted to binary and converted back to message formats using the code generated by the protoc compiler for various languages.
