Data Distribution Service for Real-Time Systems (DDS) is the OMG publish/subscribe standard that aims to enable scalable, real-time, dependable, high performance and interoperable data exchanges. DDS introduces a virtual Global Data Space where applications can share information by simply reading and writing data-objects addressed by means of an application-defined name (Topic) and a key. Large numbers of publishers and subscribers on DDS can create huge amounts of Topic data. The commonly accepted approach to large-scale real-time data management is to use a database for persistence. This paper provides an integral solution for data distribution and database management in the real-time applications space. This paper outlines a mapping between DDS and DBMS meta-model and DDS-DB integration mechanism for supporting data persistence. The prototypes of mapping tools have been implemented. This paper also concludes with general remarks and a discussion of future works.
