The Archive Development Kit (ADK) is a tool for developing archiving solutions. It also prepares the runtime environment for archiving. From a technical viewpoint, it is an intermediate layer between the application program and the archive that provides all the functions required for archiving data.
The ADK functions are required for archiving and for subsequent access to archived data. The ADK automatically performs the hardware-dependent adjustments (such as code page and number format) and structural changes that are required when archive files are created. When the archive files are accessed later, the ADK temporarily converts data that was archived using earlier mySAP Business Suite Solution releases (in the case of SAP R/3, this applies to releases back to and including 2.1).
The following graphic illustrates how the ADK’s role in the archiving concept.
