Data Serialization and Deserialization#

oneDAL provides interfaces for serialization and deserialization of data objects, which are an essential technique for data exchange between devices and for implementing data recovery mechanisms on a device failure.

The InputDataArchive class provides interfaces for creation of a serialized object archive. The OutputDataArchive class provides interfaces for deserialization of an object from the archive.

A general structure of an archive is as follows:

The first segment contains the archive header, the last segment contains the archive footer, and all other segments contain a segment header and a segment footer.

Data Archive Structure#

Headers and footers contain information required to reconstruct the archived object.

All serializable objects, such as numeric tables, a data dictionary, and models, have serialization and deserialization methods. These methods take input archive and output archive, respectively, as method parameters.
