Fusion Database Architecture
Distributed Com (DCOM) is fusions main application protocol. DCOM enables Fusion to treat each tier as a specific
component. Fusion communicates with other systems via XMAL and uses XML templates to apply client-specific business
rules prior to placement. Fusion works well with tasks assigned outside the realm of a defined procedure, is written
in Visual Basic 6.0/Visual C++ and includes multiple layers of hierarchy in the form of class, objects and complexity.
Fusion has a small footprint considering its rich functionality and requires minimal resources in a wide variety of
hardware environments. Transparent data representation is achieved via XML.
Each Fusion component has a number of attributes defining which services and policies are utilized (Com and Applications).
These components include object pooling, transactional components and built in component security, Just in Time Activation
(JIT), queried components and application recycling. Fusion COM+ architecture includes a COM+ event system service.
Components supported by the COM+ event system include subscriber events, COM+ event system score, event class subscription
in registration and the Fusion component of calls and method. Fusion COM+ events are useful for connecting independently
developed applications and allows for rapid application development. In addition to providing mission critical data
services and workflow, Fusion provides guaranteed priority based message delivery, utilizes highly efficient routing,
provides bulletproof security. It supports both synchronous and asynchronous scenarios that require high performance.
