....[EK91] Changes can be detected by comparing data snapshots. Keys can be used to efficiently compute the changes, as described in [LGM96] ffl In client server systems, an interface between application and server can be used to analyze the client requests and announce detected changes [KLB96] ffl If the component DBS is an object oriented DBS, the stored objects can be modified by an overriding technique [SS95] Any critical method will have to be refined by adding operations that announce changes. This approach restricts the autonomy of local applications, since the local ....

....[WBT92] from Texas Instruments, Inc. provide a good starting point to understand how components should be designed for unbundling. The practical benefit of unbundling is illustrated for the active DBMSs REACH [BZBW95] and SAMOS [GFV96] and for a mediator which is developed on top of Persistence [KLB96], Pers94] The whole systems are becoming more modular and lean if the unbundled components are not required. Additionally, in the case of active DBMSs we show the limitations of unbundling when the state changes of objects should be detected as relevant events. The remainder of this paper gives ....
....precompiler [Deut94] However, if state changes should be detected as in the active DBMS NAOS [CCS94] a strict layered architecture is impossible and the OODBMS needs some major modifications. 3. 2 A Mediator Based on Persistence A mediator which uses Persistence [Pers94] is described in [KLB96] to enforce global consistency between relational legacy systems. Persistence itself provides the facilities to access RDBMSs like Oracle or Sybase in an object oriented application. Access Layer (ROM Library) Generated Classes Object Model Persistence Oracle Sybase Informix Ingres C Application ....
