Built with multi tier architecture using secure CORBA and sophisticated WebFlow Java front end allowing task composition
-
tasks defined in XML and can be saved/re-executed/edited
|
|
Kerberos built on Secure CORBA today but PKI Security fine
|
|
All object interfaces defined in XML and so front end totally independent of middle tier implementation
|
|
Supports Dataflow and more general object based computing model (executing objects linked by events)
|
|
Middle Tier Components based on Javabean model
|
|
Custom Middle-tier event model consistent with security
|
|
Middle Tier is wrappers (proxies) and so insensitive to performance problems in CORBA or RMI
|
|
XML Interface between Middle Tier and backend -- object model for backend not required
