General Replication
Key Terms
Batch Replication
This term describes a replication mode of the File Replication Module (DFM). In this mode, files are transferred in regular intervals at the times specified in the corresponding replication order.
Data Exchange Module (EER)
This module controls the organization of file transfers and data replication as
well as storage of the corresponding meta information at distributed sites. The
files are provided and checked in by the FileServer. However, the FileServer does
not control the actual data exchange. Document files are then stored in the local
vault.
DDM
Distributed Data Management is the basic concept of the General
Replication Module (DDM), the File Replication (DFM), and the Data Distribution
Module (EER). The General Replication Module (DDM) manages data that is distributed
over several locations and vaults and which can be accessed using the other two
modules.
DFM
Distributed File Management describes the function of the File Replication Module (DFM).
EER
EDB Extract and Replication describes the concept of the Data Distribution Module (EER).
Local vaults
Vaults of a specific distributed site in which replicated data is to be stored
locally.
Replication, data replication
Exchange of data (e.g. document files or files containing meta data) between several distributed locations. The files are later stored in the local vault.
File Replication Module (DFM)
This module controls the replication of document files for several distributed
sites. The transfer mode is selected as part of the check-out procedure: The transfer
may be initiated immediately or at a specific time (initiated using a batch process).
The FileSever module is used for the distribution of files. Document files are
then stored in the local vault.
