	fuzzy variables with many values
	an inference engine capable of forward, backward, and mixed chaining
	control over the algebra used when combining fuzzy/uncertainty values
	"how-and-why" querying of the inference process
	many other advanced capabilities

GURU 4GL constructs

	screen/forms package
	menu/window functions
	report generator
	text processor
	spreadsheet
	real-time event handling
	"C" programming language interface
	natural language interface

Benefits of using GURU

Flexibility and Performance
GURU outpaces the competition by supporting direct representation of fuzzy reasoning, as well as 16 certainty factor Algebra choices.

Fuzzy Variables and Certainty Factors
GURU uses fuzzy variables with multiple simultaneous values and certainty factors to effectively handle the uncertainty inherent in human knowledge.

Object-Based Technology
GURU uses object-based technology and procedural language to give uncompromising control over the entire range of the development process.

Unified Environment
The GURU supertool designs expert systems that automatically access information stored in databases, change spreadsheet cell values, or generate reports.

KGL Programming Language
At the core of GURU is KGL, a knowledge and object-based fourth-generation programming language, including a full self-contained relational database. KGL far exceeds other 4GLs by blending compiled and interpreted code into a powerful tool that binds GURU's expert system and knowledge-processing capabilities into one unified environment.

New Application Solutions
GURU has the power to develop smart data-processing applications with embedded reasoning and a competitive edge. GURU applications take decision-support analysis into new realms, considering uncertain information, exploring alternatives, and making recommendations.

Data Storage and Manipulation
BLOBs, or Binary Large OBjects, store any kind of information (text, programs, graphics, digitized images, and sound) in variable-length records that can be accessed with standard SQL queries just like conventional database records.

Compatibility With Popular Windows Programs
With the GURU ODBC Driver, data may be easily imported into reports, spreadsheets, word processing functions, and more by way of programs supporting ODBC sources such as Crystal Reports, Microsoft Access, and Microsoft Word and Excel (through Microsoft Query).

Backwards Compatibility
GURU runs existing KnowledgeMan programs, with conversion requiring no substantive changes.

GURU is available for IBM PC compatibles running 32-bit Windows.
