What is G2
G2®: Real-Time Business Rules Engine (BRE) for Mission-Critical Applications
The G2 platform uniquely combines real-time reasoning technologies,
including rules, workflows, procedures, object modeling, simulation, and graphics,
in a single development and deployment environment.
G2 transforms real-time operations data into automated decisions and
actions, all in real time. G2 applications work in concert with existing operational
systems, including enterprise systems, databases, automation systems, data
historians, network management systems, telemetry systems, and many more.
With G2, application builders can use Gensym's Xtreme Consulting methodology
to rapidly design using prototyping and simulation, develop iteratively, deploy,
and continuously adapt their reasoning-driven solutions.
G2 is the BRE platform of choice for a wide variety of real-time, mission-critical
solutions offered by Gensym's expanding network of OEM, VAR, SI, and
Guru partners.
From AI to Expert Systems to Business Rules Engines
Today's business rule engines evolved from artificial intelligence (AI) and
expert system technologies.
Business rule engines, which apply decision-making logic, enable
automation of activities that have historically required the direct attention
of human specialists.
Since 1988, Gensym has extended the AI and expert system roots of G2
into the world's leading business rules engine platform for real-time,
mission-critical operations.
G2 has been proven time and again for the most demanding applications
that emulate the real-time reasoning power of human experts as they
assess, diagnose, and respond to unusual operating situations or as they
seek to optimize operations.
G2 Gensym Programming
G2 Gensym Programming leverages the unique extreme programming
capabilities of the G2 real-time rule engine platform. G2 empowers
developers with the ability to define, validate, deploy, and continuously
improve applications within a single environment. With G2 Gensym
Programming, application developers tightly control project scope and results
by rapidly planning, continuously assessing progress, and adapting rule-based
logic on the fly without stopping to compile or relink. All phases of
development are extremely iterative, rapid, and agile - for instance first
prototypes are usually up and running within days.
Gensym's G2 Gensym Programming achieves results by:

G2 ReThink for Rule-Driven
Business Process Management
G2 DNA-Decision Now Architecture
DNA structures the logic of rule-driven, real-time decision
management applications.
With G2 DNA, application builders architect their G2 solutions to deliver the
following functionality:
 Detect - Detection of a real-time operational process event
 Diagnose - From an event, a diagnosis of the situation assesses the root
cause, severity, and impact of potential problems. s
 Respond - For problems with costly impacts, reaching a timely
decision for the appropriate response is critical.
 Model - Decision logic and decision making is all enabled by rich
object-oriented models that encompass both the operational
process and the underlying rule logic. G2GL
 Optimize - Through the combination of real-time rule logic and
optimization, G2 makes online, real-time optimization practical.
DECISION ARCHITECTURE
The G2 PLATFORM (BRE)
Why use it?
•
G2 delivers competitive advantage through smarter real-time operational
decisions and by cutting application project risks.
For real-time, mission-critical operations, G2 applications:
•
•
•
•
•
Maximize performance through smarter decisions that increase throughput,
quality, and efficiency
Improve availability of assets and services by proactively detecting and
resolving problems
Increase operational agility through better coordination and scheduling of
activities
Increase application agility through immediate, real-time updating of
application logic
Improve decision making through dynamic modeling and simulation of
alternative operational configurations and decision logic
Why use it?
For application builders, G2 cuts project risks by:
• Embracing an iterative, Xtreme Consulting methodology that yields rapid
prototypes and short times-to-completion of deployed applications
• Boosting developer productivity vs. traditional programming through its
comprehensive development and deployment environment and its non-stop
coding, which applies all logic changes immediately in real time
• Readily integrating and embedding with real-time operational systems
through high-performance APIs and off-the-shelf drivers that support the
most common IT standards
• Improving application quality by testing logic prior to deployment through
simulation
• Protecting application investments through support of Windows, UNIX, and
Linux operating systems and a tradition of forward compatibility
BOOST DEVELOPER PRODUCTIVITY
G2 is a powerful platform for
original equipment manufacturers (OEMs),
value-added resellers (VARs),
system integrators (SIs).
consultants, and end users. Using G2, organizations:
• Rapidly prototype solutions with end users
• Achieve faster time-to-completion of projects
• Work with smaller development teams
• Lower software-maintenance costs
• More easily integrate with enterprise systems, applications, and
databases
• Quickly port across Windows, UNIX, and Linux systems
Features
Powerful Real-Time Technology
G2's rules, procedures, and object models all work efficiently in real time to enable rapid
execution of operational decisions and actions.
Standards-based Integration and Embeddability
G2's rule-engine logic, objects, data structures and UI readily integrate with operational
systems and embed within third-party applications through support of standards including
ActiveX/COM, .NET, Java RMI, SQL, ODBC, JMS, OPC, XML, HTTP, and others.
Dynamic Modeling and Simulation
G2 dynamically models and simulates systems and processes for “what-if” analysis of
alternative operational designs and real-time rule logic. Simulations can be run online to
detect problems by comparing theoretical to actual conditions. And by testing applications in
simulation mode prior to deployment, developers ensure application quality by finding and
resolving problems before going online.
Flexible Deployment across Operating Systems
G2 runs on Microsoft Windows NT/2000/2003/XP, Red Hat Linux and Linux Enterprise, Sun
Solaris SPARC, IBM AIX, HP-UX, and Compaq Tru64 UNIX. G2 applications are immediately
