Database Technology
The Data Access Layer uses Microsoft's
ADO library to interface with any ODBC compliant database,
including SQL Server, Oracle, Sybase and DB2. It applies standard
mechanisms for reporting and data management such as OLAP
and DTS.
Client Technology
The HTML client user interface is rendered using any standard
Internet browser. Clients are Intranet based, Internet based
or hybrid.
Server Technology
Vulcan runs on any network topology, and uses standard
distributed object technology (DCOM) for server-to-server
communication across domain boundaries, proxy servers and
fire-walls. In order to minimise network traffic, the system
implements data caching mechanisms, leveraging operating system
features such as shared property managers and standard data
compression algorithms.
Application Security
Vulcan provides a comprehensive, customisable role-based
security model that supports all user types from Intranet
to Internet. User and role-based access is managed with standard
COM+ mechanisms, which are administered via standard MMC plug-ins.
SiteMinder, LDAP, IBM Tivoli, Database, or proprietary systems
may also be used.
Scalability
The flexibility of the architecture
allows Vulcan to easily scale to any number of users.
As the number of users, sites or channels grows, application
servers are seamlessly added.
Communication Standards and Middleware
Communication within Vulcan:
- XML over HTTP(S) is used for Client-Server
communications
- Web components enable web servers to communicate
with remote application servers via the DCOM protocol
Communication with other systems:
- Web Services provide industry-standard
openness and security via SOAP
- Options for communication with third party
systems include MSMQ, IBM MQ series, XML/HTTP or raw TCP/IP.
For legacy systems, BCP and EDI protocols are used.
Integration with other systems
- Vulcan typically uses XML and Web
Services for integration with other systems.
- Integration with IBM CICS-type legacy systems is enabled
by Microsoft's COM Transaction Integrator (COMTI).
- Vulcan supports all popular Message-Oriented Middleware
(MOM) including MSMQ and IBM MQ series.
- Vulcan uses a DCOM Component Connector for integration
with SAP systems.
