When data structures need to be stored or transmitted to another location, such as across a network, they are serialized.įor simple, linear data (number or string) there's nothing to do. Source: CIS 2019.Ĭomputer data is generally organized in data structures such as arrays, tables, trees, classes. Illustrating object serialized to flat textual ( XML) format. How does data serialization and deserialization work?. XML, JSON, BSON, YAML, MessagePack, and protobuf are some commonly used data serialization formats. Reconstructed objects are clones of the original object.Ĭhoice of data serialization format for an application depends on factors such as data complexity, need for human readability, speed and storage space constraints. Once the serialized data is transmitted from the source machine to the destination machine, the reverse process of creating objects from the byte sequence called deserialization is carried out. Storing and exchanging data between such varying environments requires a platform-and-language-neutral data format that all systems understand. Internal binary representations of data also vary accordingly in every environment. Source: Paul 2017.ĭata serialization is the process of converting data objects present in complex data structures into a byte stream for storage, transfer and distribution purposes on physical devices.Ĭomputer systems may vary in their hardware architecture, OS, addressing mechanisms.
