Client-server architecture for fuzzy relational databases

General Arquitecture

Host RDBMS

For convert FSQL to SQL sentences

DataBase (DB)

to implement fuzzy data scheme

Fuzzy Meta-knowledge base

provides information about fuzzy structure and data contained in the DB

FSQL Server

is a module that extends SQL host capabilities

processor

Fuzzy Call Library

transforms FSQL in SQL senetnces for host RDBMS

contains functions and routines for carry out yje interface tasks

FSQL precompilers

Net Protocol and DB Drivers

Fuzzy application Programming Interface

Non Fuzzy Acces

FIRST IMPLEMENTATION

The most important elements are:

FSQL Server

FAPI

Comunication protocol

host RDBMS requirements

minimum

1.support sql syntax

2.client/server architecture

3. in some develop applications permit access to Db by SQL

4. communication protocol in diferent plataforms

Additional

1.have SQL extension for different languages

2.interface use native protocol for access data

3.packets written with procedural extension

Elements for the architecture

On-line processor of FSQL

Oracle object Server

Oracle Call Interface

SQL Net

FSQL Server

accepst client requet and transforms FSQL in PL/SQL

solves all requests of access to oracle

services are modificated into calls for programming interface

build net protocols and intercepts the request

solving request in FSQL and translate into SQL
