3.8.6) OMG/OMA/ORB/CORBA Implementation Descriptions: SUITESOFTWARE (SuiteDOME)

Overview
Variety may make life more interesting, but it only complicates the
task of connecting employees with the information they need. In a
world of heterogeneous, distributed computer systems, it's an ongoing
struggle to provide easy access to data while maintaining and
updating a collection of incompatible hardware platforms, operating
systems, applications, databases, network protocols, and the like.
To simplify the technical challenges, reduce the time and effort
required, and still be able to exploit all of an organization's
on-line data, information technology (IT) managers are turning to
middleware - run-time system software that is layered between an
application program and the operating system and that, in a
distributed, heterogeneous environment, supplies the functions that
would have been provided by the application's native operating
system.

To do this effectively, middleware must be able to interpret the
differences between operating systems, network protocols, databases,
and file systems; access and distribute data; guarantee system
security; and scale up to accommodate even the largest systems. When
middleware achieves this, it makes enterprise computing a reality.
As a result, middleware is quickly emerging as the best solution for
overcoming system incompatibilities, and middleware such as
SUITESOFTWARE's Distributed Object Management Environment (DOME)
Software System makes it possible for organizations to build large
scale, heterogeneous, distributed systems that can run virtually any
application in the enterprise, accessing virtually any data.
DOME - Covering the Enterprise
The DOME Software System is comprehensive middleware that provides
all of the essential services necessary to unify distributed
applications and data into a single system. With DOME, companies can
develop applications on any platform they choose and then easily
distribute them across heterogeneous environments throughout the
enterprise.

The DOME system can accomplish this complex task because it offers:
- an open system
- standards compliance
- object-oriented architecture
- support for heterogeneous environments
- and support for Remote Data Access (RDA), Remote Procedure
Calls (RPC), Message-Oriented Middleware (MOM), and Object Request
Broker (ORB).
o Open System
DOME is an open system that provides an interface between all of a
customer's applications, making it possible to share information
between new and legacy applications. DOME provides a solution today
and its open platform structure accommodates future technologies.
o Standards Compliant
DOME is compliant with the following standards:
- OMG/CORBA
- SAG
- MOMA
- ISO
- OLE Microsoft
- CCITT X.500
- Kerberos 5.4 (Security)
DOME allows message transfer from one object to another object,
provides the ability to find an object, register an object, register
the message interface to an object, and dynamically invoke an object.
DOME also provides object services beyond the Object Request Broker
(ORB) and contains a directory and name service that provides more
functionality than specified by the X.500 standard. Because DOME goes
beyond what many of the standards require, it makes the task of
creating distributed applications, especially in very large
distributed environments, even easier.
SUITESOFTWARE is a member of various standards groups and conforms
its products to industry standards as they are adopted.
o Object-Oriented Architecture
Because DOME's architecture is object-oriented, there are significant
benefits.
- True messaging for workflow management and EDI
- Queue- and bus-based (rather than send-based) design provides
store-and-forward, broadcasting, and subscribing functionality
- Full recovery capabilities
- Different levels of messaging service for positive/negative
acknowledgment and start-on-demand
- Hierarchical namespace with true domains for complete
scalability
- Concern registration and event notification
- Logical name translation for true aliasing
- Kerberos 5.4 compatible security/authentication and access
control
- Implementation of additional protocols through a
communications layer
- Co-existence of multiple development and/or production
environments on a single node
- Platform independent time services and exception handling
These beneficial functions have resulted in measurable time and labor
savings while freeing systems personnel to concentrate on critical
issues.
o Support for Heterogeneous Environments
DOME runs on the major UNIX platforms as well as in other interactive
computing environments, such as OS/2 and Windows.
DOME Software System Components
The DOME software system is composed of the core DOME product, DOME
SecurityTM, DOMEshellTM scripting and prototyping language, and the
DOME Data Manager (DDMTM) database access manager.

[...]

The DOME Data Manager is a complete relational DBMS engine that
provides access to distributed data.
Features
DDM provides autonomy for distributed data sites, but it also
supplies the means for consolidating data for specific applications.
It can read and write data across numerous DBMSs, and it makes
distributed data management transparent, so that the user never needs
to know the physical location of data, the server of access, or the
underlying vendor in order to process requests. From the user's
perspective, the enterprise is a single logical database located in
its entirety on the local machine. This is possible because DDM maps
the application's logical view of the environment into the
enterprise's physical environment of multiple nodes, disparate
operating systems, and multiple DBMSs.
DDM can manipulate data across a large number of databases and data
locations, and it is also interoperable. By conforming to the SQL
Access Group's Call Level Interface standard, DDM can interoperate
with any number of third-party GUI and CASE tools. Among the GUIs are
Powerbuilder,, Visual Basic,, and Uniface,. Among the CASE tools are
ERwin,, Popkin,, and Knowledgeware,.
