Data distribution service and database management systems bridge |
摘要 |
A bridge to integrate representation of global data space in Data Distribution Service (DDS) and Data Management Systems (DBMS). The DDS concept of a keyed topic and a type is mapped to the DBMS notion of a keyed table and schema representing data-object instances. Rules are specified for translating between a DBMS table record and the DDS wire format representation. Four bridge components are possible: Bridge-DDS-DBMS-Publication to store outgoing published data; Bridge-DDSDBMS-Subscription to store incoming subscribed data; Bridge-DBMS-DDS-Publication to publish changes to a DBMS table; and Bridge-DBMS-DDS-Subscription to update a DBMS Table based on received data subscriptions from the network. Mechanisms are provided for preventing publication of data seen by DDS, and for preventing application of changes already made in a DBMS table. Use cases include: data caching in a database; automatic persistency of all (or selected) global data-objects; distributing database contents; and multi-vendor database content transfer.
