In current enterprises, data are distributed over a multitude of heterogeneous, autonomous database systems. These systems are often isolated and an exchange of data among them is not easy. On the other hand, decreasing time-to-market periods and raising techniques like concurrent engineering require good support in dynamic change of data location in various granularities. Data will not reside in one database system all the time but need to be moved or duplicated concurrently to others. To fulfil this industrial requirement, we develop functionality enabling different granularities of data (object) migration among multiple database systems. The underlying architecture and concepts are being derived from a requirement analysis and extend a federated DBS approach. > |
