Common Source Data Base
 | This article provides insufficient context for those unfamiliar with the subject. |
The aim of a CSDB (Common Source Data Base, in accordance with specification S1000D) is to provide the user with automated processes to handle complete publications, to exchange data between the customer and the industry and to ensure data integrity and security during all processes, listed above.
Handle technical publication
These technical publications consisting of DataModules (DM), Illustrations (ICN) and its Info Object Instance (IO). The Info Object instance (XML file, using a special Document Type Definition) consists of DM- and ICN- references to lead the loading process into a retrieval system.
Connection between authoring and illustrating environment and data vault
Furthermore the CSDB is able to support technical authors or operators with a checking environment. The checks result in standardized files like CSV or plain text, to ensure an easy transfer to the originator of the checked data. The checks enclose tests against the business rules of the programme, against the guidance document, against the ASD/AIA Spec. 1000D and its versions or in the latest version of 1000D against the BREX datamodule (BREX DM).
ASD/AIA 1000D Data exchange
Data exchange routines and automatisms are the most important reason to develop a CSDB, to ensure a process reliability. The import and export routines can be fully automated or be performed via CSDB operator.
The components of a Data exchange package are for example:
– one data dispatch note (DDN)
– a certain ammount of datamodules (DMs) and
– all illustrations, referenced by the DMs above.
The identifier of a DDN is the (DDN-Id) found within the sgml/xml file and expressed in the filename plus related extension.
The identifier of the DM is the data module code (DMC) found within the sgml/xml file and expressed in the filename plus related extension.
The identifier of the Illustration is the illustration controll number (ICN) found within the cgm/tif/mil/cg4/etc. file and expressed in the filename plus related extension.
These packages contain all necessary informations to provide the reciever with the necessary informations.
Query and search
The CSDB must provide the complete Integrated Logistics Support (ILS) process with its information. Thus detailed query and search masks have to be delivered.
A good solution may be to use commercial off-the-shelf database products to implement business logic. The CSDB must be able to handle all file formats supported via the actual version of Spec. 1000D.
