Definicja metadata (BC-ILM)

Co znaczy METADATA (BC-ILM):

The data that is saved to the archive file along with the application data.

This data enables the archive file to be read long after its creation and in subsequent releases. Metadata includes:

Database table schema Column data type Column length Codepage used (ASCII, EBCDIC) Number format (such as integers)

This information enables the ADK to recognize and convert changes that were made between the time when the archive file was created and when it was accessed. The data is only converted at runtime, that is, during the read job; the archive file itself is not changed.
