eInfotree Electronic Document Management System Architecture for Client Server Version

eInfotree features a distributed four-tier client/server architecture that provides flexibility, extensibility and reliability. This architecture facilitates integration with other products and systems. Integration with both higher level enterprise systems as well as lower level systems such as laboratory instruments, PLCs and cell controllers is achieved with minimal effort using an open architecture and a modular Application Program Interface (API).  A number of software tools are available based on this standard API that enable implementation of demanding user requirements without any programming effort.
 

Presentation Tier

 
The Presentation Tier is based on multi-dimensional visualization using a highly intuitive multiple pane concept where all information of interest is displayed to the user on a single screen.  The presentation tier is comprised of executables and Dynamic Link Libraries (DLLs) that can be installed on the client machine or on a shared network file server.
 

Application Tier

 
The Application Tier is based on component object technology that facilitates interfacing with other systems and addition of custom functionality using an open architecture and modular Application Program Interface (API).
 

Business Tier

 
The Business Tier uses COM technology that allows addition of new business rules without affecting the existing application. The various objects for this tier can also be installed locally on the client machine or centrally on a shared network file server.
 

Data Base Tier

 
The Data Base Tier consists of components that allow user interaction with the Oracle database server used by eInfotree.  These components communicate with the database using SQL*Net, a native driver provided by Oracle. Since these components are used extensively, it is recommended that they generally be installed on the local client machine. However, if desired, these can also be installed remotely on the central file server.
 

Database Server

 
The Database Server is the final repository of all the information that is stored in eInfotree.  The performance of the system is dependent on proper configuration and tuning of the database.  It is highly recommended that a dedicated database server be used.  eInfotree provides support  for database servers on all major operating systems.  A typical application may be running the database server on a Unix box with Microsoft Windows clients.
 

Notification Server

 
A number of notification messages can be configured in eInfotree to notify users of specific database events.  The notification server is responsible for all such events. The Notification Server can be installed on the same machine as the Database Server if required.
