DOK-Trader: a CORBA persistent trader with query routing facilities
G. Craske, Zahir Tari, K.R. Kumar · 1999
Existing traders support the required functions, such as the lookup and registry of services. They are limited because they are restricted to a small number of services. The paper proposes solutions to the issues of persistence and query routing in the context of CORBA Trader to improve the performance of the core trader functions. We propose appropriate wrappers that provide database-like interfaces for the traders. This enables transparency and efficient access to persistent services. We propose a design of a full CORBA trader implementation, called DOK-Trader. It has specific functionalities, since it includes a specific routing mechanism for the trader federated queries. We demonstrate that these functionalities have led to better performance for the core CORBA trader functions.
